ADAS and Jacinto 6 Integration
Description
DRA72x ("Jacinto 6 Eco") infotainment applications processors are developed on the same architecture as
Jacinto 6 devices to meet the intense processing needs of the modern infotainment-enabled automobile
experiences.
DRA72x devices offer upward scalability to DRA74x devices, while being pin-compatible across the family,
allowing Original-Equipment Manufacturers (OEMs) and Original-Design Manufacturers (ODMs) to quickly
implement innovative connectivity technologies, speech recognition, audio streaming, and more. Jacinto 6
and Jacinto 6 Eco devices bring high processing performance through the maximum flexibility of a fully
integrated mixed processor solution.
Programmability is provided by a single-core ARM Cortex-A15 RISC CPU with Neon™ extensions and a
TI C66x VLIW floating-point DSP core. The ARM processor lets developers keep control functions
separate from other algorithms programmed on the DSP and coprocessors, thus reducing the complexity
of the system software.
Additionally, TI provides a complete set of development tools for the ARM, and DSP, including C
compilers and a debugging interface for visibility into source code execution.
The DRA72x Jacinto 6 Eco processor family is qualified according to the AEC-Q100 standard.

Ball Characteristics
Table 4-2 describes the terminal characteristics and the signals multiplexed on each ball. The following list
describes the table column headers:
1. BALL NUMBER:This column lists ball numbers on the bottom side associated with each signal on the
bottom.
2. BALL NAME: This column lists mechanical name from package device (name is taken from muxmode
0).
3. SIGNAL NAME:This column lists names of signals multiplexed on each ball (also notice that the name
of the ball is the signal name in muxmode 0).
NOTE
Table 4-2 does not take into account the subsystem multiplexing signals. Subsystem
multiplexing signals are described in Section 4.4, Signal Descriptions.
NOTE
In driver off mode, the buffer is configured in high-impedance.

NOTE
In some cases Table 4-2 may present more than one signal name per muxmode for the
same ball. First signal in the list is the dominant function as selected via
CTRL_CORE_PAD_* register.
All other signals are virtual functions that present alternate multiplexing options. This virtual
functions
are
controlled
via
CTRL_CORE_ALT_SELECT_MUX
or
CTRL_CORE_VIP_MUX_SELECT register. For more information on how to use this options,
please refer to Device TRM, Chapter Control Module, Section Pad Configuration Registers.
4. MUXMODE: Multiplexing mode number:
(a) MUXMODE 0 is the primary mode; this means that when MUXMODE=0 is set, the function
mapped on the pin corresponds to the name of the pin. The primary muxmode is not necessarily
the default muxmode.
NOTE
The default mode is the mode at the release of the reset; also see the RESET REL.
MUXMODE column.
(b) MUXMODE 1 through 15 are possible muxmodes for alternate functions. On each pin, some
muxmodes are effectively used for alternate functions, while some muxmodes are not used. Only
MUXMODE values which correspond to defined functions should be used.
5. TYPE: Signal type and direction:
– I = Input
– O = Output
– IO = Input or Output
– D = Open drain
– DS = Differential Signaling
– A = Analog
– PWR = Power
– GND = Ground
– CAP = LDO Capacitor
6. BALL RESET STATE: The state of the terminal at power-on reset:
– drive 0 (OFF): The buffer drives VOL (pulldown or pullup resistor not activated)
– drive 1 (OFF): The buffer drives VOH (pulldown or pullup resistor not activated)
– OFF: High-impedance
– PD: High-impedance with an active pulldown resistor
– PU: High-impedance with an active pullup resistor
7. BALL RESET REL. STATE: The state of the terminal at the deactivation of the rstoutn signal (also
mapped to the PRCM SYS_WARM_OUT_RST signal)
– drive 0 (OFF): The buffer drives VOL (pulldown or pullup resistor not activated)
– drive clk (OFF): The buffer drives a toggling clock (pulldown or pullup resistor not activated)
– drive 1 (OFF): The buffer drives VOH (pulldown or pullup resistor not activated)
– OFF: High-impedance
– PD: High-impedance with an active pulldown resistor
– PU: High-impedance with an active pullup resistor

rstoutn signal (also mapped to the PRCM SYS_WARM_OUT_RST signal).
9. IO VOLTAGE VALUE: This column describes the IO voltage value (VDDS supply).
10. POWER: The voltage supply that powers the terminal IO buffers.
11. HYS: Indicates if the input buffer is with hysteresis:
– Yes: With hysteresis
– No: Without hysteresis
An empty box means "Yes".
NOTE
For more information, see the hysteresis values in Section 5.7, Electrical Characteristics.
12. BUFFER TYPE: Drive strength of the associated output buffer.
NOTE
For programmable buffer strength:
– The default value is given in Table 4-2.
– A note describes all possible values according to the selected muxmode.
13. PULLUP / PULLDOWN TYPE: Denotes the presence of an internal pullup or pulldown resistor.
Pullup and pulldown resistors can be enabled or disabled via software.
14. DSIS: The deselected input state (DSIS) indicates the state driven on the peripheral input (logic "0" or
logic "1") when the peripheral pin function is not selected by any of the PINCNTLx registers.
– 0: Logic 0 driven on the peripheral's input signal port.
– 1: Logic 1 driven on the peripheral's input signal port.
– blank: Pin state driven on the peripheral's input signal port.
NOTE
Configuring two pins to the same input signal is not supported as it can yield unexpected
results. This can be easily prevented with the proper software configuration (Hi-Z mode is not
an input signal).
NOTE
When a pad is set into a multiplexing mode which is not defined by pin multiplexing, that
pad’s behavior is undefined. This should be avoided.
NOTE
Some of the EMIF1 signals have an additional state change at the release of porz. The state
that the signals change to at the release of porz is as follows:
drive 0 (OFF) for: ddr1_csn0, ddr1_ck, ddr1_nck, ddr1_casn, ddr1_rasn, ddr1_wen,
ddr1_ba[2:0], ddr1_a[15:0].
OFF for: ddr1_ecc_d[7:0], ddr1_dqm[3:0], ddr1_dqm_ecc, ddr1_dqs[3:0], ddr1_dqsn[3:0],
ddr1_dqs_ecc, ddr1_dqsn_ecc, ddr1_d[31:0].
NOTE
ECC is not available on this device, but signal names are retained for consistency with the
DRA7xx family of devices.

(1) NA in this table stands for Not Applicable.
(2) For more information on recommended operating conditions, see Table 5-4, Recommended Operating Conditions.
(3) The pullup or pulldown block strength is equal to: minimum = 50 μA, typical = 100 μA, maximum = 250 μA.
(4) The output impedance settings of this IO cell are programmable; by default, the value is DS[1:0] = 10, this means 40 Ω. For more information on DS[1:0] register configuration, see the
Device TRM.
(5) IO drive strength for usb1_dp, usb1_dm, usb2_dp and usb2_dm: minimum 18.3 mA, maximum 89 mA (for a power supply vdda33v_usb1 and vdda33v_usb2 = 3.46 V).
(6) Minimum PU = 900 Ω, maximum PU = 3.090 kΩ and minimum PD = 14.25 kΩ, maximum PD = 24.8 kΩ.
For more information, see chapter 7 of the USB2.0 specification, in particular section Signaling / Device Speed Identification.
(7) This function will not be supported on some pin-compatible roadmap devices. Pin compatibility can be maintained in the future by not using these GPIO signals.
(8) In PUx / PDy, x and y = 60 to 200 μA.
The output impedance settings (or drive strengths) of this IO are programmable (34 Ω, 40 Ω, 48 Ω, 60 Ω, 80 Ω) depending on the values of the I[2:0] registers.

Multiplexing Characteristics
Table 4-3 describes the device multiplexing (no characteristics are available in this table).
NOTE
This table doesn't take into account subsystem multiplexing signals. Subsystem multiplexing signals are described in Section 4.4, Signal
Descriptions.

NOTE
For more information, see the Control Module / Control Module Functional Description / PAD Functional Multiplexing and Configuration
section of the Device TRM.
NOTE
Configuring two pins to the same input signal is not supported as it can yield unexpected results. This can be easily prevented with the
proper software configuration (Hi-Z mode is not an input signal).
NOTE
When a pad is set into a multiplexing mode which is not defined by pin multiplexing, that pad’s behavior is undefined. This should be
avoided.
NOTE
In some cases Table 4-3 may present more than one signal per muxmode for the same ball. First signal in the list is the dominant function
as selected via CTRL_CORE_PAD_* register.
All other signals are virtual functions that present alternate multiplexing options. This virtual functions are controlled via
CTRL_CORE_ALT_SELECT_MUX or CTRL_CORE_VIP_MUX_SELECT register. For more information on how to use this options,
please refer to Device TRM, Chapter Control Module, Section Pad Configuration Registers.
NOTE
ECC is not available on this device, but signal names are retained for consistency with the DRA7xx family of devices.
CAUTION
The I/O timings provided in Section 7, Timing Requirements and Switching Characteristics are valid only if signals within
a single IOSET are used. The IOSETs are defined in the corresponding tables.
NOTE
Dual rank support is not available on this device, but signal names are retained for consistency with the DRA7xx family of devices.

clock input. Any nonmonotonicity in voltage that occurs at the pad loopback clock pin between VIH and VIL must be less than VHYS.
(2) The gpio6_16.clkout1 signal can be used as an “always-on” alternative to gpmc_clk provided that the external device can support the
associated timing. See Table 7-23 GPMC/NOR Flash Interface Switching Characteristics - Synchronous Mode - Default and Table 7-25
GPMC/NOR Flash Interface Switching Characteristics - Synchronous Mode - Alternate for timing information.

RMII_MHZ_50_CLK(1)
DESCRIPTION
(1) This clock signal is implemented as 'pad loopback' inside the device - the output signal is looped back through the input buffer to serve
as the internal reference signal. Series termination is recommended (as close to device pin as possible) to improve signal integrity of the
clock input. Any nonmonotonicity in voltage that occurs at the pad loopback clock pin between VIH and VIL must be less than VHYS.
(2) Note that rstoutn is only valid after vddshv3 is valid. If the rstoutn signal will be used as a reset into other devices attached to the SOC, it
must be AND'ed with porz. This will prevent glitches occurring during supply ramping being propagated.

(1) This signal must be kept 0 if device power supplies are not valid during RTC mode and 1 during normal operation. This can typically be
achieved by connecting rtc_iso to the same signal driving porz (not rtc_porz) with appropriate voltage level translation if necessary.

DESCRIPTION
Non maskable interrupt input, active-low. This pin can be optionally routed to the
DSP NMI input or as generic input to the ARM cores. Note that by default this pin
has an internal pulldown resistor enabled. This internal pulldown should be disabled
or countered by a stronger external pullup resistor before routing to the DSP or
ARM processors.

(1) Refer to Power on Hours table Table 5-3 for limitations.
(2) The voltage at the device ball should never be below the MIN voltage or above the MAX voltage for any amount of time. This
requirement includes dynamic voltage events such as AC ripple, voltage transients, voltage dips, etc.
(3) The DC voltage at the device ball should never be above the MAX DC voltage to avoid impact on device reliability and lifetime POH
(Power-On-Hours). The MAX DC voltage is defined as the highest allowed DC regulated voltage, without transients, seen at the ball.

(1) The voltage ranges in this table are preliminary, and final voltage ranges may be different than shown. Systems should be designed with
the ability to modify the voltage to comply with future recommendations.
(2) In a typical implementation, the power supply should target the NOM voltage.
(3) The voltage at the device ball should never be below the MIN voltage or above the MAX voltage for any amount of time. This
requirement includes dynamic voltage events such as AC ripple, voltage transients, voltage dips, etc.
(4) The DC voltage at the device ball should never be above the MAX DC voltage to avoid impact on device reliability and lifetime POH
(Power-On-Hours). The MAX DC voltage is defined as the highest allowed DC regulated voltage, without transients, seen at the ball.
(5) For all OPPs, AVS must be enabled to avoid impact on device reliability, lifetime POH (Power-On-Hours), and device power.
(6) The AVS voltages are device-dependent, voltage domain-dependent, and OPP-dependent. They must be read from the
STD_FUSE_OPP Registers. For information about STD_FUSE_OPP Registers address, please refer to Control Module Section of the
TRM. The power supply should be adjustable over the following ranges for each required OPP:
– OPP_NOM for MPU: 0.85 V – 1.15 V
– OPP_NOM for CORE and Others: 0.85 V - 1.15 V
– OPP_OD: 0.94 V - 1.15 V
– OPP_HIGH: 1.05 V - 1.25 V
The AVS voltages will be within the above specified ranges.
(7) VD_RTC can optionally be tied to VD_CORE and operate at the VD_CORE AVS voltages.
(8) The power supply must be programmed with the AVS voltages for the MPU and the CORE voltage domain, either just after the ROM
boot or at the earliest possible time in the secondary boot loader before there is significant activity seen on these domains.

Maximum Supported Frequency
Device modules either receive their clock directly from an external clock input, directly from a PLL, or from
a PRCM. Table 5-9 lists the clock source options for each module on this device, along with the maximum
frequency that module can accept. To ensure proper module functionality, the device PLLs and dividers
must be programmed not to exceed the maximum frequencies listed in this table.

(1) VITH is the voltage at which the receiver is required to detect a high state in the input signal.
(2) VITL is the voltage at which the receiver is required to detect a low state in the input signal. VITL is larger than the maximum single-ended
line high voltage during HS transmission. Therefore, both low-power (LP) receivers will detect low during HS signaling.
(3) To reduce noise sensitivity on the received signal, the LP receiver is required to incorporate a hysteresis, VHYST. VHYST is the difference
between the VITH threshold and the VITL threshold.
(4) VITL is the voltage at which the receiver is required to detect a low state in the input signal. Specification is relaxed for detecting 0 during
ultralow power (ULP) state. The LP receiver is not required to detect HS single-ended voltage as 0 in this state.
(5) Excluding possible additional RF interference of 200 mVPP beyond 450 MHz.
(6) This value includes a ground difference of 50 mV between the transmitter and the receiver, the static common-mode level tolerance and
variations below 450 MHz.
(7) This number corresponds to the VODMAX transmitter.
(8) Common mode is defined as the average voltage level of X and Y: VCMRX = (VX + VY) / 2.
(9) Common mode ripple may be due to tR or tF and transmission line impairments in the PCB.
(10) For more information regarding the pin name (or ball name) and corresponding signal name, see Table 4-7 CSI 2 Signal Descriptions.

vddshv[1-7,9-11] is allowed to ramp down at either of the two points shown in the timing diagram in either 1.8V mode or in 3.3V mode. If
vddshv[1-7,9-11] ramps down at the later time in the diagram then the board design must guarantee that the vddshv[1-7,9-11] rail is
never higher than 2.0 V above the vdds18v rail.
(8) vddshv8 is separated out to show support for dual voltage. If a dedicated LDO/supply source is used for vddshv8, then vddshv8 ramp
down should occur at one of the two earliest points in the timing diagram. If vddshv8 is powered by the same supply source as the other
vddshvn rails, then it is allowed to ramp down at either of the last two points in the timing diagram.

NOTE
For more information, see Power Reset and Clock Management / PRCM Environment /
External Clock Signal and Power Reset / PRCM Functional Description / PRCM Clock
Manager Functional Description section of the Device TRM.
NOTE
Audio Back End (ABE) module is not supported for this family of devices, but “ABE” name is
still present in some clock or DPLL names.
The device operation requires the following clocks:
• The 32 kHz frequency is used for low frequency operation. It supplies the wake-up domain for
operation in lowest power mode. This is an optional clock and will be supplied by on chip divider + mux
(FUNC_32K_CLK) incase it is not available on external pin.
• The system clocks, SYS_CLKIN1(Mandatory) and SYS_CLKIN2(Optional) are the main clock sources
of the device. They supply the reference clock to the DPLLs as well as functional clock to several
modules.
The Device also embeds an internal free-running 32-kHz oscillator that is always active as long as the the
wake-up (WKUP) domain is supplied.
Figure 6-1 shows the external input clock sources and the output clocks to peripherals.

(1) To switch from bypass mode to crystal or from crystal mode to bypass mode, there is a waiting time about 100 μs; however, if the chip
comes from bypass mode to crystal mode the crystal will start-up after time mentioned in Table 6-6, tsX parameter.
(2) Before the processor boots up and the oscillator is set to bypass mode, there is a waiting time when the internal oscillator is in
application mode and receives a wave. The switching time in this case is about 100 μs.

(1) Period jitter is meant here as follows:
– The maximum value is the difference between the longest measured clock period and the expected clock period
– The minimum value is the difference between the shortest measured clock period and the expected clock period
(2) Crystal characteristics should account for tolerance+stability+aging.
(3) The Period jitter requirement for osc1 can be relaxed to 0.02*tc(xiosc1) under the following constraints:
a.The osc1/SYS_CLK2 clock bypasses all device PLLs
b.The osc1/SYS_CLK2 clock is only used to source the DSS pixel clock outputs

NOTE
For more information, see:
• Power, Reset, and Clock Management / Clock Management Functional / Internal Clock
Sources / Generators / Generic DPLL Overview Section
and
• Display Subsystem / Display Subsystem Overview section of the Device TRM.
To generate high-frequency clocks, the device supports multiple on-chip DPLLs controlled directly by the
PRCM module. They are of two types: type A and type B DPLLs.
•
They have their own independent power domain (each one embeds its own switch and can be
controlled as an independent functional power domain)
• They are fed with ALWAYS ON system clock, with independent control per DPLL.
The different DPLLs managed by the PRCM are listed below:
• DPLL_MPU: It supplies the MPU subsystem clocking internally.
• DPLL_IVA: It feeds the IVA subsystem clocking.
• DPLL_CORE: It supplies all interface clocks and also few module functional clocks.
• DPLL_PER: It supplies several clock sources: a 192-MHz clock for the display functional clock, a
96-MHz functional clock to subsystems and peripherals.
• DPLL_ABE: It provides clocks to various modules within the device.
• DPLL_USB: It provides 960M clock for USB modules (USB1/2/3/4).
• DPLL_GMAC: It supplies several clocks for the Gigabit Ethernet Switch (GMAC_SW).
• DPLL_DSP: It feeds the DSP Subsystem clocking.
• DPLL_GPU: It supplies clock for the GPU Subsystem.
• DPLL_DDR: It generates clocks for the two External Memory Interface (EMIF) controllers and their
associated EMIF PHYs.
• DPLL_PCIE_REF: It provides reference clock for the APLL_PCIE in PCIE Subsystem.
• APLL_PCIE: It feeds clocks for the device Peripheral Component Interconnect Express (PCIe)
controllers.
NOTE
The following DPLLs are controlled by the clock manager located in the always-on Core
power domain (CM_CORE_AON):
• DPLL_MPU, DPLL_IVA, DPLL_CORE, DPLL_ABE, DPLL_DDR, DPLL_GMAC,
DPLL_PCIE_REF, DPLL_PER, DPLL_USB, DPLL_DSP, DPLL_GPU, APLL_PCIE_REF.
For more information on CM_CORE_AON and CM_CORE or PRCM DPLLs, see the Power, Reset, and
Clock Management (PRCM) chapter of the Device TRM.

6.2.1
SPRS956B – MARCH 2016 – REVISED JANUARY 2017
DPLL Characteristics
The DPLL has three relevant input clocks. One of them is the reference clock (CLKINP) used to generated
the synthesized clock but can also be used as the bypass clock whenever the DPLL enters a bypass
mode. It is therefore mandatory. The second one is a fast bypass clock (CLKINPULOW) used when
selected as the bypass clock and is optional. The third clock (CLKINPHIF) is explained in the next
paragraph.
The DPLL has three output clocks (namely CLKOUT, CLKOUTX2, and CLKOUTHIF). CLKOUT and
CLKOUTX2 run at the bypass frequency whenever the DPLL enters a bypass mode. Both of them are
generated from the lock frequency divided by a post-divider (namely M2 post-divider). The third clock,
CLKOUTHIF, has no automatic bypass capability. It is an output of a post-divider (M3 post-divider) with
the input clock selectable between the internal lock clock (Fdpll) and CLKINPHIF input of the PLL through
an asynchronous multplexing.
For more information, see the Power Reset Controller Management chapter of the Device TRM.

7.1
Timing Test Conditions
All timing requirements and switching characteristics are valid over the recommended operating conditions
unless otherwise specified.
7.2
7.2.1
Interface Clock Specifications
Interface Clock Terminology
The interface clock is used at the system level to sequence the data and/or to control transfers accordingly
with the interface protocol.
7.2.2
Interface Clock Frequency
The two interface clock characteristics are:
• The maximum clock frequency
• The maximum operating frequency
The interface clock frequency documented in this document is the maximum clock frequency, which
corresponds to the maximum frequency programmable on this output clock. This frequency defines the
maximum limit supported by the Device IC and does not take into account any system consideration
(PCB, peripherals).
The system designer will have to consider these system considerations and the Device IC timing
characteristics as well to define properly the maximum operating frequency that corresponds to the
maximum frequency supported to transfer the data on this interface.
7.3
Timing Parameters and Information
The timing parameter symbols used in the timing requirement and switching characteristic tables are
created in accordance with JEDEC Standard 100. To shorten the symbols, some of pin names and other
related terminologies have been abbreviated as follows:

NOTE: The data sheet provides timing at the device pin. For output timing analysis, the tester pin electronics and its transmission line effects must be
taken into account. A transmission line with a delay of 2 ns can be used to produce the desired transmission line effect. The transmission line is
intended as a load only. It is not necessary to add or subtract the transmission line delay (2 ns) from the data sheet timings.
Input requirements in this data sheet are tested with an input slew rate of < 4 Volts per nanosecond (4 V/ns) at the device pin.

1.8V and 3.3V Signal Transition Rates
The default SLEWCONTROL settings in each pad configuration register must be used to guaranteed
timings, unless specific instructions otherwise are given in the individual timing sub-sections of the
datasheet.
All timings are tested with an input edge rate of 4 volts per nanosecond (4 V/ns).
7.3.1.3
Timing Parameters and Board Routing Analysis
The timing parameter values specified in this data manual do not include delays by board routes. As a
good board design practice, such delays must always be taken into account. Timing values may be
adjusted by increasing/decreasing such delays. TI recommends using the available I/O buffer information
specification (IBIS) models to analyze the timing characteristics correctly. To properly use IBIS models to
attain accurate timing analysis for a given system, see the Using IBIS Models for timing Analysis
application report (literature number SPRA839). If needed, external logic hardware such as buffers may be
used to compensate any timing differences.
7.4
Recommended Clock and Control Signal Transition Behavior
All clocks and control signals must transition between VIH and VIL (or between VIL and VIH) in a monotonic
manner. Monotonic transitions are more easily guaranteed with faster switching signals. Slower input
transitions are more susceptible to glitches due to noise and special care should be taken for slow input
clocks.
7.5
Virtual and Manual I/O Timing Modes
Some of the timings described in the following sections require the use of Virtual or Manual I/O Timing
Modes. Table 7-2 provides a summary of the Virtual and Manual I/O Timing Modes across all device
interfaces. The individual interface timing sections found later in this document provide the full description
of each applicable Virtual and Manual I/O Timing Mode. Refer to the "Pad Configuration" section of the
TRM for the procedure on implementing the Virtual and Manual Timing Modes in a system.

Manual IO Timings Modes must be used to guaranteed some IO timings for VIP1. See Table 7-2 Modes Summary for a list of IO timings requiring
the use of Manual IO Timings Modes. See Table 7-9 Manual Functions Mapping for VIN1A (IOSET2/3) and VIN1B (IOSET4) and VIN2B (IOSET8)
for a definition of the Manual modes.
Table 7-9 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in the CFG_x registers.

(1) Some signals listed are virtual functions that present alternate multiplexing options. These virtual functions are controlled via CTRL_CORE_ALT_SELECT_MUX or
CTRL_CORE_VIP_MUX_SELECT registers. For more information on how to use these options, please refer to Device TRM, Chapter Control Module, Section Pad Configuration
Registers.
Manual IO Timings Modes must be used to guaranteed some IO timings for VIP1. See Table 7-2 Modes Summary for a list of IO timings requiring
the use of Manual IO Timings Modes. See Table 7-10 Manual Functions Mapping for VIN1A (IOSET4/5/6) and VIN2A (IOSET7/8/9) for a definition
of the Manual modes.
Table 7-10 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in the CFG_x registers.

SPRS956B – MARCH 2016 – REVISED JANUARY 2017
Display Subsystem - Video Output Ports
Three Display Parallel Interfaces (DPI) channels are available in DSS named DPI Video Output 1, DPI
Video Output 2 and DPI Video Output 3.
NOTE
The DPI Video Output i (i = 1 to 3) interface is also referred to as VOUTi.
Every VOUT interface consists of:
• 24-bit data bus (data[23:0])
• Horizontal synchronization signal (HSYNC)
• Vertical synchronization signal (VSYNC)
• Data enable (DE)
• Field ID (FID)
• Pixel clock (CLK)
NOTE
For more information, see the Display Subsystem chapter of the Device TRM.
CAUTION
The I/O timings provided in this section are valid only if signals within a single
IOSET are used. The IOSETs are defined in Table 7-16.
CAUTION
The I/O Timings provided in this section are valid only for some DSS usage
modes when the corresponding Virtual I/O Timings or Manual I/O Timings are
configured as described in the tables found in this section.
CAUTION
All pads/balls configured as vouti_* signals must be programmed to use slow
slew rate by setting the corresponding CTRL_CORE_PAD_*[SLEWCONTROL]
register field to SLOW (0b1).
Table 7-14, Table 7-15 and Figure 7-6 assume testing over the recommended operating conditions and
electrical characteristic conditions.

The device has 16 general-purpose (GP) timers (TIMER1 - TIMER16), two watchdog timers, and a 32-kHz
synchronized timer (COUNTER_32K) that have the following features:
• Dedicated input trigger for capture mode and dedicated output trigger/pulse width modulation (PWM)
signal
• Interrupts generated on overflow, compare, and capture
• Free-running 32-bit upward counter
• Supported modes:
– Compare and capture modes
– Auto-reload mode
– Start-stop mode
• On-the-fly read/write register (while counting)
The device has two system watchdog timer (WD_TIMER1 and WD_TIMER2) that have the following
features:
• Free-running 32-bit upward counter
• On-the-fly read/write register (while counting)
• Reset upon occurrence of a timer overflow condition
The device includes one instance of the 32-bit watchdog timer: WD_TIMER2, also called the MPU
watchdog timer.
The watchdog timer is used to provide a recovery mechanism for the device in the event of a fault
condition, such as a non-exiting code loop.
NOTE
For additional information on the Timer Module, see the Device TRM.
7.13 Inter-Integrated Circuit Interface (I2C)
The device includes 6 inter-integrated circuit (I2C) modules which provide an interface to other devices
compliant with Philips Semiconductors Inter-IC bus (I2C-bus™) specification version 2.1. External
components attached to this 2-wire serial bus can transmit/receive 8-bit data to/from the device through
the I2C module.
NOTE
Note that, on I2C1 and I2C2, due to characteristics of the open drain IO cells, HS mode is
not supported.
NOTE
Inter-integrated circuit i (i=1 to 6) module is also referred to as I2Ci.
NOTE
For more information, see the Multimaster High-Speed I2C Controller section of the Device
TRM.

(1) The I2C pins SDA and SCL do not feature fail-safe I/O buffers. These pins could potentially draw current when the device is powered
down.
(2) A Fast-mode I2C-bus™ device can be used in a Standard-mode I2C-bus system, but the requirement tsu(SDA-SCLH)≥ 250 ns must then be
met. This will automatically be the case if the device does not stretch the LOW period of the SCL signal. If such a device does stretch
the LOW period of the SCL signal, it must output the next data bit to the SDA line tr max + tsu(SDA-SCLH)= 1000 + 250 = 1250 ns
(according to the Standard-mode I2C-Bus Specification) before the SCL line is released.
(3) A device must internally provide a hold time of at least 300 ns for the SDA signal (referred to the VIHmin of the SCL signal) to bridge the
undefined region of the falling edge of SCL.
(4) The maximum th(SDA-SCLL) has only to be met if the device does not stretch the low period [tw(SCLL)] of the SCL signal.
(5) Cb = total capacitance of one bus line in pF. If mixed with HS-mode devices, faster fall-times are allowed.

(1) I2C HS-Mode is only supported on I2C3/4/5/6. I2C HS-Mode is not supported on I2C1/2.
(2) For bus line loads Cb between 100 and 400 pF the timing parameters must be linearly interpolated.
(3) A device must internally provide a Data hold time to bridge the undefined part between VIH and VIL of the falling edge of the SCLH
signal. An input circuit with a threshold as low as possible for the falling edge of the SCLH signal minimizes this hold time.

(2) Software must properly configure the I2C module registers to achieve the timings shown in this table. See the Device TRM for details.
(3) These timings apply only to I2C1 and I2C2. I2C3, I2C4, I2C5 and I2C6 use standard LVCMOS buffers to emulate open-drain buffers
and their rise/fall times should be referenced in the device IBIS model.
NOTE
I2C emulation is achieved by configuring the LVCMOS buffers to output Hi-Z instead of
driving high when transmitting logic-1.

7.15 Universal Asynchronous Receiver Transmitter (UART)
The UART performs serial-to-parallel conversions on data received from a peripheral device and parallelto-serial conversion on data received from the CPU. There are 10 UART modules in the device. Only one
UART supports IrDA features. Each UART can be used for configuration and data exchange with a
number of external peripheral devices or interprocessor communication between devices
The UARTi (where i = 1 to 10) include the following features:
• 16C750 compatibility
• 64-byte FIFO buffer for receiver and 64-byte FIFO for transmitter
• Baud generation based on programmable divisors N (where N = 1…16 384) operating from a fixed
functional clock of 48 MHz or 192 MHz
• Break character detection and generation
• Configurable data format:
– Data bit: 5, 6, 7, or 8 bits
– Parity bit: Even, odd, none
– Stop-bit: 1, 1.5, 2 bit(s)
• Flow control: Hardware (RTS/CTS) or software (XON/XOFF)
• Only UART1 module has extended modem control signals (CD, RI, DTR, DSR)
• Only UART3 supports IrDA
NOTE
For more information, see the UART section of the Device TRM.

7.16 Multichannel Serial Peripheral Interface (McSPI)
The McSPI is a master/slave synchronous serial bus. There are four separate McSPI modules (SPI1,
SPI2, SPI3, and SPI4) in the device. All these four modules support up to four external devices (four chip
selects) and are able to work as both master and slave.
The McSPI modules include the following main features:
• Serial clock with programmable frequency, polarity, and phase for each channel
• Wide selection of SPI word lengths, ranging from 4 to 32 bits
• Up to four master channels, or single channel in slave mode
• Master multichannel mode:
– Full duplex/half duplex
– Transmit-only/receive-only/transmit-and-receive modes
– Flexible input/output (I/O) port controls per channel
– Programmable clock granularity
– SPI configuration per channel. This means, clock definition, polarity enabling and word width
• Power management through wake-up capabilities
• Programmable timing control between chip select and external clock generation
• Built-in FIFO available for a single channel.
• Each SPI module supports multiple chip select pins spim_cs[i], where i = 1 to 4.
NOTE
For more information, see the Serial Communication Interface section of the device TRM.
NOTE
The McSPIm module (m = 1 to 4) is also referred to as SPIm.

7.17 Quad Serial Peripheral Interface (QSPI)
The Quad SPI (QSPI) module is a type of SPI module that allows single, dual or quad read access to
external SPI devices. This module has a memory mapped register interface, which provides a direct
interface for accessing data from external SPI devices and thus simplifying software requirements. It
works as a master only. There is one QSPI module in the device and it is primary intended for fast
booting from quad-SPI flash memories.
General SPI features:
• Programmable clock divider
• Six pin interface (DCLK, CS_N, DOUT, DIN, QDIN1, QDIN2)
• 4 external chip select signals
• Support for 3-, 4- or 6-pin SPI interface
• Programmable CS_N to DOUT delay from 0 to 3 DCLKs
• Programmable signal polarities
• Programmable active clock edge
• Software controllable interface allowing for any type of SPI transfer
NOTE
For more information, see the Quad Serial Peripheral Interface section of the Device TRM.
CAUTION
The I/O Timings provided in this section are only valid when all QSPI Chip
Selects used in a system are configured to use the same Clock Mode (either
Clock Mode 0 or Clock Mode 3).
CAUTION
The I/O Timings provided in this section are valid only for some QSPI usage
modes when the corresponding Virtual I/O Timings or Manual I/O Timings are
configured as described in the tables found in this section.

(1) The Y parameter is defined as follows:
If DCLK_DIV is 0 or ODD then, Y equals 0.5.
If DCLK_DIV is EVEN then, Y equals (DCLK_DIV/2) / (DCLK_DIV+1).
For best performance, it is recommended to use a DCLK_DIV of 0 or ODD to minimize the duty cycle distortion. The HSDIVIDER on
CLKOUTX2_H13 output of DPLL_PER can be used to achieve the desired clock divider ratio. All required details about clock division
factor DCLK_DIV can be found in the device-specific Technical Reference Manual.

(1) P = SCLK period.
(2) Clock Modes 1 and 2 are not supported.
(3) The Device captures data on the falling clock edge in Clock Mode 0 and 3, as opposed to the traditional rising clock edge. Although
non-standard, the falling-edge-based setup and hold time timings have been designed to be compatible with standard SPI devices that
launch data on the falling edge in Clock Modes 0 and 3.

NOTE
To configure the desired Manual IO Timing Mode the user must follow the steps described in
section Manual IO Timing Modes of the Device TRM.
The associated registers to configure are listed in the CFG REGISTER column. For more
information see the Control Module chapter in the Device TRM.
Manual IO Timings Modes must be used to guaranteed some IO timings for QSPI. See Table 7-2 Modes
Summary for a list of IO timings requiring the use of Manual IO Timings Modes. See Table 7-45 Manual
Functions Mapping for QSPI for a definition of the Manual modes.
Table 7-45 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in
the CFG_x registers.

7.18 Multichannel Audio Serial Port (McASP)
The multichannel audio serial port (McASP) functions as a general-purpose audio serial port optimized for
the needs of multichannel audio applications. The McASP is useful for time-division multiplexed (TDM)
stream, Inter-Integrated Sound (I2S) protocols, and intercomponent digital audio interface transmission
(DIT).
The device have integrated 8 McASP modules (McASP1-McASP8) with:
• McASP1 and McASP2 modules supporting 16 channels with independent TX/RX clock/sync domain
• McASP3 through McASP8 modules supporting 4 channels with independent TX/RX clock/sync domain
NOTE
For more information, see the Serial Communication Interface section of the Device TRM.
CAUTION
The I/O Timings provided in this section are valid only for some McASP usage
modes when the corresponding Virtual I/O Timings or Manual I/O Timings are
configured as described in the tables found in this section.
Table 7-46, Table 7-47, Table 7-48 and Figure 7-41 present Timing Requirements for McASP1 to

7.23.3 GMAC RMII Timings
The main reference clock REF_CLK (RMII_50MHZ_CLK) of RMII interface is internally supplied from
PRCM. The source of this clock could be either externally sourced from the RMII_MHZ_50_CLK pin of the
device or internally generated from DPLL_GMAC output clock GMAC_RMII_HS_CLK. Please see the
PRCM chapter of the device TRM for full details about RMII reference clock.

Module Chapter.
7.26 General-Purpose Interface (GPIO)
The general-purpose interface combines eight general-purpose input/output (GPIO) banks. Each GPIO
module provides up to 32 dedicated general-purpose pins with input and output capabilities; thus, the
general-purpose interface supports up to 215 pins.
These pins can be configured for the following applications:
• Data input (capture)/output (drive)
• Keyboard interface with a debounce cell
• Interrupt generation in active mode upon the detection of external events. Detected events are
processed by two parallel independent interrupt-generation submodules to support biprocessor
operations
• Wake-up request generation in idle mode upon the detection of external events
NOTE
For more information, see the General-Purpose Interface chapter of the Device TRM.

7.29.1 IEEE 1149.1 Standard-Test-Access Port (JTAG)
The JTAG (IEEE Standard 1149.1-1990 Standard-Test-Access Port and Boundary Scan Architecture)
interface is used for BSDL testing and emulation of the device. The trstn pin only needs to be released
when it is necessary to use a JTAG controller to debug the device or exercise the device's boundary scan
functionality. For maximum reliability, the device includes an internal Pulldown (IPD) on the trstn pin to
ensure that trstn is always asserted upon power up and the device's internal emulation logic is always
properly initialized. JTAG controllers from Texas Instruments actively drive trstn high. However, some
third-party JTAG controllers may not drive trstn high but expect the use of a Pullup resistor on trstn. When
using this type of JTAG controller, assert trstn to initialize the device after powerup and externally drive
trstn high before attempting any emulation or boundary-scan operations.
The main JTAG features include:
• 32KB embedded trace buffer (ETB)
• 5-pin system trace interface for debug
• Supports Advanced Event Triggering (AET)
• All processors can be emulated via JTAG ports
• All functions on EMU pins of the device:
– EMU[1:0] - cross-triggering, boot mode (WIR), STM trace
– EMU[4:2] - STM trace only (single direction)

8 Applications, Implementation, and Layout
NOTE
Information in the following Applications section is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. TI's customers are responsible for
determining suitability of components for their purposes. Customers should validate and test
their design implementation to confirm system functionality.
8.1
Introduction
This chapter is intended to communicate, guide and illustrate a PCB design strategy resulting in a PCB
that can support TI’s latest Application Processor. This Processor is a high-performance processor
designed for automotive Infotainment based on enhanced OMAP™ architecture integrated on a 28-nm
CMOS process technology.
These guidelines first focus on designing a robust Power Delivery Network (PDN) which is essential to
achieve the desirable high performance processing available on Device. The general principles and stepby-step approach for implementing good power integrity (PI) with specific requirements will be described
for the key Device power domains.
TI strongly believes that simulating a PCB’s proposed PDN is required for first pass PCB design success.
Key Device processor high-current power domains need to be evaluated for Power Rail IR Drop,
Decoupling Capacitor Loop-Inductance and Power Rail Target Impedance. Only then can a PCB’s PDN
performance be truly accessed by comparing these model PI parameters vs. TI’s recommended values.
Ultimately for any high-volume product, TI recommends conducting a “Processor PDN Validation” test on
prototype PCBs across processor “split lots” to verify PDN robustness meets desired performance goals
for each customer’s worst-case scenario. Please contact your TI representative to receive guidance on
PDN PI modeling and validation testing.
Likewise, the methodology and requirements needed to route Device high-speed, differential interfaces
(i.e. USB2.0, USB3.0, HDMI, PCI, SATA), single-ended interfaces (i.e. DDR3, QSPI) and general purpose
interfaces using LVCMOS drivers that meet timing requirements while minimizing signal integrity (SI)
distortions on the PCB’s signaling traces. Signal trace lengths and flight times are aligned with FR-4
standard specification for PCBs.
Several different PCB layout stack-up examples have been presented to illustrate a typical number of
layers, signal assignments and controlled impedance requirements. Different Device interface signals
demand more or less complexity for routing and controlled impedance stack-ups. Optimizing the PCB’s
PDN stack-up needs with all of these different types of signal interfaces will ultimately determine the final
layer count and layer assignments in each customer’s PCB design.
This guideline must be used as a supplement in complement to TI’s Application Processor, Power
Management IC (PMIC) and Audio Companion components along with other TI component technical
documentation (i.e. Technical Reference Manual, Data Manual, Data Sheets, Silicon Errata, Pin-Out
Spreadsheet, Application Notes, etc.).
NOTE
Notwithstanding any provision to the contrary, TI makes no warranty expressed, implied, or
statutory, including any implied warranty of merchantability of fitness for a specific purpose,
for customer boards. The data described in this appendix are intended as guidelines only.
NOTE
These PCB guidelines are in a draft maturity and consequently, are subject to change
depending on design verification testing conducted during IC development and validation.

8.1.1
SPRS956B – MARCH 2016 – REVISED JANUARY 2017
Initial Requirements and Guidelines
Unless otherwise specified, the characteristic impedance for single-ended interfaces is recommended to
be between 35 Ω and 65 Ω to minimize the overshoot or undershoot on far-end loads.
Characteristic impedance for differential interfaces must be routed as differential traces on the same layer.
The trace width and spacing must be chosen to yield the recommended differential impedance. For more
information see Section 8.5.1.
The PDN must be optimized for low trace resistance and low trace inductance for all high-current power
nets from PMIC to the device.
An external interface using a connector must be protected following the IEC61000-4-2 level 4 system
ESD.
8.2
Power Optimizations
This section describes the necessary steps for designing a robust Power Distribution Network (PDN):
• Section 8.2.1, Step 1: PCB Stack-up
• Section 8.2.2, Step 2: Physical Placement
• Section 8.2.3, Step 3: Static Analysis
• Section 8.2.4, Step 4: Frequency Analysis
8.2.1
Step 1: PCB Stack-up
The PCB stack-up (layer assignment) is an important factor in determining the optimal performance of the
power distribution system. An optimized PCB stack-up for higher power integrity performance can be
achieved by following these recommendations:
• Power and ground plane pairs must be closely coupled together. The capacitance formed between the
planes can decouple the power supply at high frequencies. Whenever possible, the power and ground
planes must be solid to provide continuous return path for return current.
• Use a thin dielectric between the power and ground plane pair. Capacitance is inversely proportional to
the separation of the plane pair. Minimizing the separation distance (the dielectric thickness)
maximizes the capacitance.
• Optimize the power and ground plane pair carrying high current supplies to key component power
domains as close as possible to the same surface where these components are placed (see Figure 81). This will help to minimize “loop inductance” encountered between supply decoupling capacitors and
component supply inputs and between power and ground plane pairs.
NOTE
1-2oz Cu weight for power / ground plane is preferred to enable better PCB heat spreading,
helping to reduce Processor junction temperatures. In addition, it is preferable to have the
power / ground planes be adjacent to the PCB surface on which the Processor is mounted.

Figure 8-1. Minimize Loop Inductance With Proper Layer Assignment
The placement of power and ground planes in the PCB stackup (determined by layer assignment) has a
significant impact on the parasitic inductances of power current path as shown in Figure 8-1. For this
reason, it is recommended to consider layer order in the early stages of the PCB PDN design cycle,
putting high-priority supplies in the top half of the stackup (assuming high load and priority components
are mounted on the top-side of PCB) and low-priority supplies in the bottom half of the stackup as shown
in the examples below (vias have parasitic inductances which impact the bottom layers more, so it is
advised to put the sensitive and high-priority power supplies on the top/same layers).
8.2.2
Step 2: Physical Placement
A critical step in designing an optimized PDN is that proper care must be taken to making sure that the
initial floor planning of the PCB layout is done with good power integrity design guidelines in mind. The
following points are important for optimizing a PCB’s PDN:
• Minimizing the physical distance between power sources and key high load components is the first
step toward optimization. Placing source and load components on the same side of the PCB is
desirable. This will minimize via inductance impact for high current loads and steps
• External trace routing between components must be as wide as possible. The wider the traces, the
lower the DC resistance and consequently the lower the static IR drop.
• Whenever possible for the internal layers (routing and plane), wide traces and copper area fills are
preferred for PDN layout. The routing of power nets in plane provide for more interplane capacitance
and improved high frequency performance of the PDN.
• Whenever possible, use a via to component pin/pad ratio of 1:1 or better (i.e. especially decoupling
capacitors, power inductors and current sensing resistors). Do not share vias among multiple
capacitors for connecting power supply and ground planes.
• Placement of vias must be as close as possible or even within a component’s solder pad if the PCB
technology you are using provides this capability.
• To avoid any “ampacity” issue – maximum current-carrying capacity of each transitional via should be
evaluated to determine the appropriate number of vias required to connect components.
Adding vias to bring the “via-to-pad” ratio to 1:1 will improve PDN performance.
• For noise sensitive power supplies (i.e. Phase Lock-Loops, analog signals like audio and video), a Gnd
shield can be used to isolate coplanar supplies that may have high step currents or high frequency
switching transitions from coupling into low-noise supplies.

Step 3: Static Analysis
Delivering reliable power to circuits is always of critical importance because voltage drops (also known as
IR drops) can happen at every level within an electronic system, on-chip, within a package, and across the
board. Robust system performance can only be ensured by understanding how the system elements will
perform under typical stressful Use Cases. Therefore, it is a good practice to perform a Static or DC
Analysis.
Static or DC analysis and design methodology results in a PDN design that minimizes voltage or IR drops
across power and ground planes, traces and vias. This ensures the application processor’s internal
transistors will be operating within their specified voltage ranges for proper functionality. The amount of IR
drop that will be encounter is based upon amount power drawn for a desired Use Case and PCB trace
(widths, geometry and number of parallel traces) and via (size, type and number) characteristics.
Components that are distant from their power source are particularly susceptible to IR drop. Designs that
rely on battery power must minimize voltage drops to avoid unacceptable power loss that can negatively
impact system performance. Early assessments a PDN’s static (DC) performance helps to determine
basic power distribution parameters such as best system input power point, optimal PCB layer stackup,
and copper area needed for load currents.

Ohm’s Law (V = I × R) relates conduction current to voltage drop. At DC, the relation coefficient is a
constant and represents the resistance of the conductor. Even current carrying conductors will dissipate
power at high currents even though their resistance may be very small. Both voltage drop and power
dissipation are proportional to the resistance of the conductor.
Figure 8-4 shows a PCB-level static IR drop budget defined between the power management device
(PMIC) pins and the application processor’s balls when the PMIC is supplying power.
• It is highly recommended to physically place the PMIC as close as possible to the processor and on
the same side. The orientation of the PMIC vs. processor should be aligned to minimize distance for
the highest current rail.

Figure 8-4. Static IR Drop Budget for PCB Only
The system-level IR drop budget is made up of three portions: on-chip, package, and PCB board. Static IR
or DC analysis/design methodology consists of designing the PDN such that the voltage drop (under DC
operating conditions) across power and ground pads of the transistors of the application processor device
is within a specified value of the nominal voltage for proper functionality of the device.
A PCB system-level voltage drop budget for proper device functionality is typically 1.5% of nominal
voltage. For a 1.35-V supply, this would be ≤20 mV.
To accurately analyze PCB static IR drop, the actual geometry of the PDN must be modeled properly and
simulated to accurately characterize long distribution paths, copper weight impacts, electro-migration
violations of current-carrying vias, and “Swiss-cheese” effects via placement has on power rails. It is
recommended to perform the following analyses:
• Lumped resistance/IR drop analysis
• Distributed resistance/IR drop analysis
NOTE
The PMIC companion device supporting this processor has been designed with voltage
sensing feedback loop capabilities that enable a remote sense of the SMPS output voltage at
the point of use.
The NOTE above means the SMPS feedback signals and returns must be routed across PCB and
connected to the Device input power ball for which a particular SMPS is supplying power. This feedback
loop provides compensation for some of the voltage drop encountered across the PDN within limits. As
such, the effective resistance of the PDN within this loop should be determined in order to optimize
voltage compensation loop performance. The resistance of two PDN segments are of interest: one from
the power inductor/bulk power filtering capacitor node to the Processor’s input power and second is the
entire PDN route from SMPS output pin/ball to the Processor input power.
In the following sections each methodology is described in detail and an example has been provided of
analysis flow that can be used by the PCB designer to validate compliance to the requirements on their
PCB PDN design.
8.2.3.1
PDN Resistance and IR Drop
Lumped methodology consists of grouping all of the power pins on both the PMIC (voltage source) and
processor (current sink) devices. Then the PMIC source is set to an expected Use Case voltage level and
the processor load has its Use Case current sink value set as well. Now the lumped/effective resistance
for the power rail trace/plane routes can be determine based upon the actual layout’s power rail etch wide,
shape, length, via count and placement Figure 8-5 illustrates the pin-grouping/lumped concept.
The lumped methodology consists of importing the PCB layout database (from Cadence Allegro tool or
any other layout design tool) into the static IR drop modeling and simulation tool of preference for the PCB
designer. This is followed by applying the correct PCB stack-up information (thickness, material
properties) of the PCB dielectric and metallization layers. The material properties of dielectric consist of
permittivity (Dk) and loss tangent (Df).

Step 4: Frequency Analysis
Delivering low noise voltage sources are very important to allowing a system to operate at the lowest
possible Operational Performance Point (OPP) for any one Use Case. An OPP is a combination of the
supply voltage level and clocking rate for key internal processor domains. A SCH and PCB designed to
provide low noise voltage supplies will then enable the processor to enter optimal OPPs for each Use
Case that in turn will minimize power dissipation and junction temperatures on-die. Therefore, it is a good
engineering practice to perform a Frequency Analysis over the key power domains.
Frequency analysis and design methodology results in a PDN design that minimizes transient noise
voltages at the processor’s input power balls. This allows the processor’s internal transistors to operate
near the minimum specified operating supply voltage levels. To accomplish this one must evaluate how a
voltage supply will change due to impedance variations over frequency. This analysis will focus on the
decoupling capacitor network (VDD_xxx and VSS/Gnd rails) at the load. Sufficient capacitance with a
distribution of self-resonant points will provide for an overall lower impedance vs frequency response for
each power domain.
Decoupling components that are distant from their load’s input power are susceptible to encountering
spreading loop inductance from the PCB design. Early analysis of each key power domain’s frequency
response helps to determine basic decoupling capacitor placement, optimal footprint, layer assignment,
and types needed for minimizing supply voltage noise/fluctuations due to switching and load current
transients.
NOTE
Evaluation of loop inductance values for decoupling capacitors placed ~300mils closer to the
load’s input power balls has shown an 18% reduction in loop inductance due to reduced
distance.
•
Decoupling capacitors must be carefully placed in order to minimize loop inductance impact on supply
voltage transients. A real capacitor has characteristics not only of capacitance but also inductance and
resistance.
Figure 8-6 shows the parasitic model of a real capacitor. A real capacitor must be treated as an RLC
circuit with effective series resistance (ESR) and effective series inductance (ESL).

Figure 8-8. Typical Impedance Profile of a Capacitor
Because a capacitor has series inductance and resistance that impacts its effectiveness, it is important
that the following recommendations are adopted in placing capacitors on the PDN.
Wherever possible, mount the capacitor with the geometry that minimizes the mounting inductance and
resistance. This was shown earlier in Figure 8-1. The capacitor mounting inductance and resistance
values include the inductance and resistance of the pads, trace, and vias. Whenever possible, use
footprints that have the lowest inductance configuration as shown in Figure 8-9
The length of a trace used to connect a capacitor has a big impact on parasitic inductance and resistance
of the mounting. This trace must be as short and as wide as possible. wherever possible, minimize
distance to supply and Gnd vias by locating vias nearby or within the capacitor’s solder pad landing.
Further improvements can be made to the mounting by placing vias to the side of capacitor lands or
doubling the number of vias as shown in Figure 8-9. If the PCB manufacturing processes allow it and if
cost-effective, via-in-pad (VIP) geometries are strongly recommended.

SPRS956B – MARCH 2016 – REVISED JANUARY 2017
In addition to mounting inductance and resistance associated with placing a capacitor on the PCB, the
effectiveness of a decoupling capacitor also depends on the spreading inductance and resistance that the
capacitor sees with respect to the load. The spreading inductance and resistance is strongly dependent on
the layer assignment in the PCB stack-up. Therefore, try to minimize X, Y and Z dimensions where the Z
is due to PCB thickness (as shown in Figure 8-9).
From left (highest inductance) to right (lowest inductance) the capacitor footprint types shown in Figure 89 are known as:
• 2-via, Skinny End Exit (2vSEE)
• 2-via, Wide End Exit (2vWEE)
• 2-via, Wide Side Exit (2vWSE)

Evaluation of loop inductance values for decoupling capacitor footprints 2vSEE (worst case)
vs 4vWSE (2nd best) has shown a 30% reduction in inductance when 4vWSE footprint was
used in place of 2vSEE.
Decoupling Capacitor (Dcap) Strategy:
1. Use lowest inductance footprint and trace connection scheme possible for given PCB technology and
layout area in order to minimize Dcap loop inductance to power pin as much as possible (see Figure 89).
2. Place Dcaps on “same-side” as component within their power plane outline to minimize “decoupling
loop inductance”. Target distance to power pin should be less than ~500mils depending upon PCB
layout characteristics (plane's layer assignment and solid nature). Use PI modeling CAD tool to verify
minimum inductance for top vs bottom-side placement.
3. Place Dcaps on “opposite-side” as component within their power plane outline if “same-side” is not
feasible or if distance to power pin is greater than ~500mils for top-side location. Use PI modeling CAD
tool to verify minimum inductance for top vs bottom-side placement.
4. Use minimum 10mil trace width for all voltage and gnd planes connections (i.e. Dcap pads, component
power pins, etc.).

System ESD Generic Guidelines
8.2.5.1
System ESD Generic PCB Guideline
Protection devices must be placed close to the ESD source which means close to the connector. This
allows the device to subtract the energy associated with an ESD strike before it reaches the internal
circuitry of the application board.
To help minimize the residual voltage pulse that will be built-up at the protection device due to its nonzero
turn-on impedance, it is mandatory to route the ESD device with minimum stub length so that the lowresistive, low-inductive path from the signal to the ground is granted and not increasing the impedance
between signal and ground.
For ESD protection array being railed to a power supply when no decoupling capacitor is available in close
vicinity, consider using a decoupling capacitor (≥ 0.1 µF) tight to the VCC pin of the ESD protection. A
positive strike will be partially diverted to this capacitance resulting in a lower residual voltage pulse.
Ensure that there is sufficient metallization for the supply of signals at the interconnect side (VCC and
GND in Figure 8-10) from connector to external protection because the interconnect may see between 15A to 30-A current in a short period of time during the ESD event.

Miscellaneous EMC Guidelines to Mitigate ESD Immunity
Avoid running critical signal traces (clocks, resets, interrupts, control signals, and so forth) near PCB
edges.
Add high frequency filtering: Decoupling capacitors close to the receivers rather than close to the
drivers to minimize ESD coupling.
Put a ground (guard) ring around the entire periphery of the PCB to act as a lightning rod.
Connect the guard ring to the PCB ground plane to provide a low impedance path for ESD-coupled
current on the ring.
Fill unused portions of the PCB with ground plane.
Minimize circuit loops between power and ground by using multilayer PCB with dedicated power and
ground planes.
Shield long line length (strip lines) to minimize radiated ESD.
Avoid running traces over split ground planes. It is better to use a bridge connecting the two planes in
one area.

Always route signal traces and their associated ground returns as close to one another as possible to
minimize the loop area enclosed by current flow:
– At high frequencies current follows the path of least inductance.
– At low frequencies current flows through the path of least resistance.
ESD Protection System Design Consideration
ESD protection system design consideration is covered in Section 8.5.2.2 of this document. The following
are additional considerations for ESD protection in a system.
• Metallic shielding for both ESD and EMI
• Chassis GND isolation from the board GND
• Air gap designed on board to absorb ESD energy
• Clamping diodes to absorb ESD energy
• Capacitors to divert ESD energy
• The use of external ESD components on the DP/DM lines may affect signal quality and are not
recommended.

EMI / EMC Issues Prevention
All high-speed digital integrated circuits can be sources of unwanted radiation, which can affect nearby
sensitive circuitry and cause the final product to have radiated emissions levels above the limits allowed
by the EMC regulations if some preventative steps are not taken.
Likewise, analog and digital circuits can be susceptible to interference from the outside world and picked
up by the circuitry interconnections.
To minimize the potential for EMI/EMC issues, the following guidelines are recommended to be followed.
8.2.6.1
Signal Bandwidth
To evaluate the frequency of a digital signal, an estimated rule of thumb is to consider its bandwidth fBW
with respect to its rise time, tR:
fBW ≈ 0.35 / tR
This frequency actually corresponds to the break point in the signal spectrum, where the harmonics start
to decay at 40 dB per decade instead of 20 dB per decade.
8.2.6.2
Signal Routing
8.2.6.2.1 Signal Routing—Sensitive Signals and Shielding
Keep radio frequency (RF) sensitive circuitry (like GPS receivers, GSM/WCDMA, Bluetooth/WLAN
transceivers, frequency modulation (FM) radio) away from high-speed ICs (the device, power and audio
manager, chargers, memories, and so forth) and ideally on the opposite side of the PCB. For improved
protection it is recommended to place these emission sources in a shield can. If the shield can have a
removable lid (two-piece shield), ensure there is low contact impedance between the fence and the lid.
Leave some space between the lid and the components under it to limit the high-frequency currents
induced in the lid. Limit the shield size to put any potential shield resonances above the frequencies of
interest; see Figure 8-8, Typical Impedance Profile of a Capacitor.
8.2.6.2.2 Signal Routing—Outer Layer Routing
In case there is a need to use the outer layers for routing outside of shielded areas, it is recommended to
route only static signals and ensure that these static signals do not carry any high-frequency components
(due to parasitic coupling with other signals). In case of long traces, make provision for a bypass capacitor
near the signal source.
Routing of high-frequency clock signals on outer layers, even for a short distance, is discouraged,
because their emissions energy is concentrated at the discrete harmonics and can become significant
even with poor radiators.
Coplanar shielding of traces on outer layers (placing ground near the sides of a track along its length) is
effective only if the distance between the trace sides and the ground is smaller that the trace height above
the ground reference plane. For modern multilayer PCBs this is often not possible, so coplanar shielding
will not be effective. Do not route high-frequency traces near the periphery of the PCB, as the lack of a
ground reference near the trace edges can increase EMI: see Section 8.2.6.3, Ground Guidelines.
8.2.6.3
Ground Guidelines
8.2.6.3.1 PCB Outer Layers
Ideally the areas on the top and bottom layers of the PCB that are not enclosed by a shield should be
filled with ground after the routing is completed and connected with an adequate number of vias to the
ground on the inner ground planes.

8.2.6.3.2 Metallic Frames
Ensure that all metallic parts are well connected to the PCB ground (like LCD screens metallic frames,
antennas reference planes, connector cages, flex cables grounds, and so forth). If using flex PCB ribbon
cables to bring high-frequency signals off the PCB, ensure they are adequately shielded (coaxial cables or
flex ribbons with a solid reference ground).
8.2.6.3.3 Connectors
For high-frequency signals going to connectors choose a fully shielded connector, if possible (for example,
SD card connectors). For signals going to external connectors or which are routed over long distances, it
is recommended to reduce their bandwidth by using low-pass filters (resistor, capacitor (RC) combinations
or lossy ferrite inductors). These filters will help to prevent emissions from the board and can also improve
the immunity from external disturbances.
8.2.6.3.4 Guard Ring on PCB Edges
The major advantage of a multilayer PCB with ground-plane is the ground return path below each and
every signal or power trace.
As shown in Figure 8-12 the field lines of the signal return to PCB ground as long as an infinite ground is
available.
Traces near the PCB-edges do not have this infinite ground and therefore may radiate more than the
others. Thus, signals (clocks) or power traces (core power) identified to be critical must not be routed in
the vicinity of PCB edges, or, if not avoidable, must be accompanied by a guard ring on the PCB edge.

The intention of the guard ring is that HF-energy, that otherwise would have been emitted from the PCB
edge, is reflected back into the board where it partially will be absorbed. For this purpose ground traces on
the borders of all layers (including power layer) must be applied as shown in Figure 8-13.
As these traces must have the same (HF–) potential as the ground plane they must be connected to the
ground plane at least every 10 mm.

For the optimum solution, the AGND and the DGND planes must be connected together at the power

– 1st area is from DC (0Hz) up to Fpmic (typ a few 100 kHz) where a PMIC’s transient response
characteristic (i.e. Switching Freq, Compensation Loop BW) dominate. A PDN’s Z is typically very
low due to power filtering & bulk capacitor values when PDN has very low trace resistance (i.e.
good Reff performance). The goal is to maintain a smoothly increasing Z that is less than Zt1 over
this low frequency range. This will ensure that a max transient current event will not cause a
voltage drop more than the PMIC’s current step response can support (typ 3%).
– 2nd area is from Fpmic up to Fpcb (typ 20-100MHz) where a PCB’s inherent characteristics (i.e.
parasitic capacitance, planar spreading inductances) dominate. A PDN’s Z will naturally increase
with frequency. At frequencies between Fpmic up to Fpcb, the goal is to maintain a smoothly
increasing Z to be less than Zt2. This will ensue that the high frequency content of a max transient
current event will not cause a voltage drop to be more than 5% of the min supply voltage.

(1) Minimum value for each PCB capacitor: 100 nF.
(2) Among the different capacitors, 470 nF is recommended (not required) to filter at 5-MHz to 10-MHz frequency range.
(3) In comparison with the EIA Class 1 dielectrics, Class 2 dielectric capacitors tend to have severe temperature drift, high dependence of
capacitance on applied voltage, high voltage coefficient of dissipation factor, high frequency coefficient of dissipation, and problems with
aging due to gradual change of crystal structure. Aging causes gradual exponential loss of capacitance and decrease of dissipation
factor.

Static PDN Analysis
One power net parameter derived from a PCB’s PDN static analysis is the Effective Resistance (Reff).
This is the total PCB power net routing resistance that is the sum of all the individual power net segments
used to deliver a supply voltage to the point of load and includes any series resistive elements (i.e. current
sensing resistor) that may be installed between the PMIC outputs and Processor inputs.
8.3.4
Dynamic PDN Analysis
Three power net parameters derived from a PCB’s PDN dynamic analysis are the Loop Inductance (LL),
Impedance (Z) and PCB Frequency of Interest (Fpcb).

LL values shown are the recommended max PCB trace inductance between a decoupling capacitor’s
power supply and ground reference terminals when viewed from the decoupling capacitor with a
“theoretical shorted” applied across the Processor’s supply inputs to ground reference.
Z values shown are the recommended max PCB trace impedances allowed between Fpmic up to Fpcb
frequency range that limits transient noise drops to no more than 5% of min supply voltage during max
transient current events.
Fpcb (Frequency of Interest) is defined to be a power rail’s max frequency after which adding a
reasonable number of decoupling capacitors no longer significantly reduces the power rail impedance
below the desired impedance target (Zt2). This is due to the dominance of the PCB’s parasitic planar
spreading and internal package inductances.

Power Supply Mapping
TPS65917 or TPS659039 are the Power Management ICs (PMICs) that should be used for the Device
designs. TI requires use of these PMICs for the following reasons:
• TI has validated their use with the Device
• Board level margins including transient response and output accuracy are analyzed and optimized for
the entire system

Support for power sequencing requirements (refer to Section 5.9 Power Supply Sequences)
Support for Adaptive Voltage Scaling (AVS) Class 0 requirements, including TI provided software
Whenever we allow for combining of rails mapped on any of the SMPSes, the PDN guidelines that are the
most stringent of the rails combined should be implemented for the particular supply rail.
It is possible that some voltage domains on the device are unused in some systems. In such cases, to
ensure device reliability, it is still required that the supply pins for the specific voltage domains are
connected to some core power supply output.
These unused supplies though can be combined with any of the core supplies that are used (active) in the
system. e.g. if IVA and GPU domains are not used, they can be combined with the CORE domain,
thereby having a single power supply driving the combined CORE, IVA and GPU domains.
For the combined rail, the following relaxations do apply:
• The AVS voltage of active rail in the combined rail needs to be used to set the power supply
• The decoupling capacitance should be set according to the active rail in the combined rail

(1) Power consumption is highly application-specific. Separate analysis must be performed to ensure output current ratings (average and
peak) is within the limits of the PMIC for all rails of the device.
(2) Dual phase (SMPS1/2) can be used as long as the peak power consumption is maintained below the SMPS1/2 capacity
(a) For the latest rated output current specifications for the TPS659039 device, please refer to the PMIC data manual.
(b) MPU power consumption is highly system dependent. A detailed power consumption estimate must be performed to confirm
compatibility. Example: Single vs Dual MPU, OPP_NOM vs OPP_OD vs OPP_HIGH, TPS659039 configured with VI≥3V vs VI<3V,
etc. Contact your TI representative for details.
(3) Refer to the PMIC data manual for the latest TPS659039 specifications.
(4) A product’s maximum ambient temperature, thermal system design & heat spreading performance could limit the maximum power
dissipation below the full PMIC capacity in order to not exceed recommended SoC max Tj.

DPLL Voltage Requirement
The voltage input to the DPLLs has a low noise requirement. Board designs should supply these voltage
inputs with a low noise LDO to ensure they are isolated from any potential digital switching noise. The
TPS65917 PMIC LDOLN output is specifically designed to meet this low noise requirement.

Dynamic analysis of this PCB design for the CORE power domain determined the vdd decoupling
capacitor loop inductance and impedance vs frequency analysis shown below. As you can see, the loop
inductance values ranged from 0.97 –1.75nH and were less than maximum 2.0nH recommended.
NOTE
Comparing loop inductances for capacitors at different distances from the SoC’s input power
balls shows an 18% reduction for caps placed closer. This was derived by averaging the
inductances for the 3 caps with distances over 800mils (Avg LL = 1.33nH) vs the 3 caps with
distances less than 600mils (Avg LL = 1.096nH).

Line spacing:
– For a line width equal to W, the spacing between two lines must be 2W, at least. This minimizes the
crosstalk between switching signals between the different lines. On the PCB, this is not achievable
everywhere (for example, when breaking signals out from the device package), but it is
recommended to follow this rule as much as possible. When violating this guideline, minimize the
length of the traces running parallel to each other (see Figure 8-19).

Length matching (unless otherwise specified):
– For bus or traces at frequencies less than 10 MHz, the trace length matching (maximum length
difference between the longest and the shortest lines) must be less than 25 mm.
– For bus or traces at frequencies greater than 10 MHz, the trace length matching (maximum length
difference between the longest and the shortest lines) must be less than 2.5 mm.
Characteristic impedance
– Unless otherwise specified, the characteristic impedance for single-ended interfaces is
recommended to be between 35-Ω and 65-Ω.
Multiple peripheral support
– For interfaces where multiple peripherals have to be supported in the star topology, the length of
each branch has to be balanced. Before closing the PCB design, it is highly recommended to verify
signal integrity based on simulations including actual PCB extraction.
QSPI Board Design and Layout Guidelines
The following section details the routing guidelines that must be observed when routing the QSPI
interfaces.
• The qspi1_sclk output signal must be looped back into the qspi1_rtclk input.
• The signal propagation delay from the qspi1_sclk ball to the QSPI device CLK input pin (A to C) must
be approximately equal to the signal propagation delay from the QSPI device CLK pin to the
qspi1_rtclk ball (C to D).
• The signal propagation delay from the QSPI device CLK pin to the qspi1_rtclk ball (C to D) must be
approximately equal to the signal propagation delay of the control and data signals between the QSPI
device and the SoC device (E to F, or F to E).
• The signal propagation delay from the qspi1_sclk signal to the series terminators (R2 = 10 Ω) near the
QSPI device must be < 450pS (~7cm as stripline or ~8cm as microstrip)
• 50 Ω PCB routing is recommended along with series terminations, as shown in Figure 8-20.

Differential Interfaces
General Routing Guidelines
To maximize signal integrity, proper routing techniques for differential signals are important for high-speed
designs. The following general routing guidelines describe the routing guidelines for differential lanes and
differential signals.
• As much as possible, no other high-frequency signals must be routed in close proximity to the
differential pair.
• Must be routed as differential traces on the same layer. The trace width and spacing must be chosen
to yield the differential impedance value recommended.
• Minimize external components on differential lanes (like external ESD, probe points).
• Through-hole pins are not recommended.
• Differential lanes mustn’t cross image planes (ground planes).
• No sharp bend on differential lanes.

8.5.2
SPRS956B – MARCH 2016 – REVISED JANUARY 2017
Number of vias on the differential pairs must be minimized, and identical on each line of the differential
pair. In case of multiple differential lanes in the same interface, all lines should have the same number
of vias.
Shielded routing is to be promoted as much as possible (for instance, signals must be routed on
internal layers that are inside power and/or ground planes).
USB 2.0 Board Design and Layout Guidelines
This section discusses schematic guidelines when designing a universal serial bus (USB) system.
8.5.2.1
Background
Clock frequencies generate the main source of energy in a USB design. The USB differential DP/DM pairs
operate in high-speed mode at 480 Mbps. System clocks can operate at 12 MHz, 48 MHz, and 60 MHz.
The USB cable can behave as a monopole antenna; take care to prevent RF currents from coupling onto
the cable.
When designing a USB board, the signals of most interest are:
• Device interface signals: Clocks and other signal/data lines that run between devices on the PCB.
• Power going into and out of the cable: The USB connector socket pin 1 (VBUS ) may be heavily
filtered and need only pass low frequency signals of less than ~100 KHz. The USB socket pin 4
(analog ground) must be able to return the current during data transmission, and must be filtered
sparingly.
• Differential twisted pair signals going out on cable, DP and DM: Depending upon the data transfer rate,
these device terminals can have signals with fundamental frequencies of 240 MHz (high speed), 6
MHz (full speed), and 750 kHz (low speed).
• External crystal circuit (device terminals XI and X0): 12 MHz, 19.2 MHz, 24 MHz, and 48 MHz
fundamental. When using an external crystal as a reference clock, a 24 MHz and higher crystal is
highly recommended.
8.5.2.2
USB PHY Layout Guide
The following sections describe in detail the specific guidelines for USB PHY Layout.
8.5.2.2.1 General Routing and Placement
Use the following routing and placement guidelines when laying out a new design for the USB physical
layer (PHY). These guidelines help minimize signal quality and electromagnetic interference (EMI)
problems on a four-or-more layer evaluation module (EVM).
• Place the USB PHY and major components on the un-routed board first. For more details, see
Section 8.5.2.2.2.3.
• Route the high-speed clock and high-speed USB differential signals with minimum trace lengths.
• Route the high-speed USB signals on the plane closest to the ground plane, whenever possible.
• Route the high-speed USB signals using a minimum of vias and corners. This reduces signal
reflections and impedance changes.
• When it becomes necessary to turn 90°, use two 45° turns or an arc instead of making a single 90°
turn. This reduces reflections on the signal traces by minimizing impedance discontinuities.
• Do not route USB traces under or near crystals, oscillators, clock signal generators, switching
regulators, mounting holes, magnetic devices or IC’s that use or duplicate clock signals.
• Avoid stubs on the high-speed USB signals because they cause signal reflections. If a stub is
unavoidable, then the stub should be less than 200 mils.
• Route all high-speed USB signal traces over continuous planes (VCC or GND), with no interruptions.
Avoid crossing over anti-etch, commonly found with plane splits.

8.5.2.2.2 Specific Guidelines for USB PHY Layout
The following sections describe in detail the specific guidelines for USB PHY Layout.
8.5.2.2.2.1 Analog, PLL, and Digital Power Supply Filtering
To minimize EMI emissions, add decoupling capacitors with a ferrite bead at power supply terminals for
the analog, phase-locked loop (PLL), and digital portions of the chip. Place this array as close to the chip
as possible to minimize the inductance of the line and noise contributions to the system. An analog and
digital supply example is shown in Figure 8-21. In case of multiple power supply pins with the same
function, tie them up to a single low-impedance point in the board and then add the decoupling capacitors,
in addition to the ferrite bead. This array of caps and ferrite bead improve EMI and jitter performance.
Take both EMI and jitter into account before altering the configuration.

Figure 8-21. Suggested Array Capacitors and a Ferrite Bead to Minimize EMI
Consider the recommendations listed below to achieve proper ESD/EMI performance:
• Use a 0.01 μF cap on each cable power VBUS line to chassis GND close to the USB connector pin.
• Use a 0.01 μF cap on each cable ground line to chassis GND next to the USB connector pin.
• If voltage regulators are used, place a 0.01 μF cap on both input and output. This is to increase the
immunity to ESD and reduce EMI. For other requirements, see the device-specific datasheet.
8.5.2.2.2.2 Analog, Digital, and PLL Partitioning
If separate power planes are used, they must be tied together at one point through a low-impedance
bridge or preferably through a ferrite bead. Care must be taken to capacitively decouple each power rail
close to the device. The analog ground, digital ground, and PLL ground must be tied together to the lowimpedance circuit board ground plane.
8.5.2.2.2.3 Board Stackup
Because of the high frequencies associated with the USB, a printed circuit board with at least four layers
is recommended; two signal layers separated by a ground and power layer as shown in Figure 8-22.

SPRS906_PCB_USB20_02
Figure 8-22. Four-Layer Board Stack-Up
The majority of signal traces should run on a single layer, preferably SIGNAL1. Immediately next to this
layer should be the GND plane, which is solid with no cuts. Avoid running signal traces across a split in
the ground or power plane. When running across split planes is unavoidable, sufficient decoupling must
be used. Minimizing the number of signal vias reduces EMI by reducing inductance at high frequencies.
8.5.2.2.2.4 Cable Connector Socket
Short the cable connector sockets directly to a small chassis ground plane (GND strap) that exists
immediately underneath the connector sockets. This shorts EMI (and ESD) directly to the chassis ground
before it gets onto the USB cable. This etch plane should be as large as possible, but all the conductors
coming off connector pins 1 through 6 must have the board signal GND plane run under. If needed, scoop
out the chassis GND strap etch to allow for the signal ground to extend under the connector pins. Note
that the etches coming from pins 1 and 4 (VBUS power and GND) should be wide and via-ed to their
respective planes as soon as possible, respecting the filtering that may be in place between the connector
pin and the plane. See Figure 8-23 for a schematic example.
Place a ferrite in series with the cable shield pins near the USB connector socket to keep EMI from getting
onto the cable shield. The ferrite bead between the cable shield and ground may be valued between 10 Ω
and 50 Ω at 100 MHz; it should be resistive to approximately 1 GHz. To keep EMI from getting onto the
cable bus power wire (a very large antenna) a ferrite may be placed in series with cable bus power,
VBUS, near the USB connector pin 1. The ferrite bead between connector pin 1 and bus power may be
valued between 47 Ω and approximately 1000 Ω at 100 MHz. It should continue being resistive out to
approximately 1 GHz, as shown in Figure 8-23.

8.5.2.2.2.5 Clock Routings
To address the system clock emissions between devices, place a ~10 to 130 Ω resistor in series with the
clock signal. Use a trial and error method of looking at the shape of the clock waveform on a high-speed
oscilloscope and of tuning the value of the resistance to minimize waveform distortion. The value on this
resistor should be as small as possible to get the desired effect. Place the resistor close to the device
generating the clock signal. If an external crystal is used, follow the guidelines detailed in the Selection
and Specification of Crystals for Texas Instruments USB 2.0 Devices (SLLA122).
When routing the clock traces from one device to another, try to use the 3W spacing rule. The distance
from the center of the clock trace to the center of any adjacent signal trace should be at least three times
the width of the clock trace. Many clocks, including slow frequency clocks, can have fast rise and fall
times. Using the 3W rule cuts down on crosstalk between traces. In general, leave space between each of
the traces running parallel between the devices. Avoid using right angles when routing traces to minimize
the routing distance and impedance discontinuities. For further protection from crosstalk, run guard traces
beside the clock signals (GND pin to GND pin), if possible. This lessens clock signal coupling, as shown in
Figure 8-24.

8.5.2.2.2.6 Crystals/Oscillator
Keep the crystal and its load capacitors close to the USB PHY pins, XI and XO (see Figure 8-25). Note
that frequencies from power sources or large capacitors can cause modulations within the clock and
should not be placed near the crystal. In these instances, errors such as dropped packets occur. A
placeholder for a resistor, in parallel with the crystal, can be incorporated in the design to assist oscillator
startup.
Power is proportional to the current squared. The current is I = C*dv/dt, because dv/dt is a function of the
PHY, current is proportional to the capacitive load. Cutting the load to 1/2 decreases the current by 1/2
and the power to 1/4 of the original value. For more details on crystal selection, see the Selection and
Specification of Crystals for Texas Instruments USB 2.0 Devices (SLLA122).

8.5.2.2.2.7 DP/DM Trace
Place the USB PHY as close as possible to the USB 2.0 connector. The signal swing during high-speed
operation on the DP/DM lines is relatively small (400 mV ± 10%), so any differential noise picked up on
the twisted pair can affect the received signal. When the DP/DM traces do not have any shielding, the
traces tend to behave like an antenna and picks up noise generated by the surrounding components in
the environment. To minimize the effect of this behavior:
• DP/DM traces should always be matched lengths and must be no more than 4 inches in length;
otherwise, the eye opening may be degraded (see Figure 8-26).
• Route DP/DM traces close together for noise rejection on differential signals, parallel to each other and
within two mils in length of each other. The measurement for trace length must be started from
device's balls.
• A high-speed USB connection is made through a shielded, twisted pair cable with a differential
characteristic impedance of 90 Ω ±15%. In layout, the impedance of DP and DM should each be 45 Ω
± 10%.
• DP/DM traces should not have any extra components to maintain signal integrity. For example, traces
cannot be routed to two USB connectors.

8.5.2.2.2.8 DP/DM Vias
When a via must be used, increase the clearance size around it to minimize its capacitance. Each via
introduces discontinuities in the signal’s transmission line and increases the chance of picking up
interference from the other layers of the board. Be careful when designing test points on twisted pair lines;
through-hole pins are not recommended.
8.5.2.2.2.9 Image Planes
An image plane is a layer of copper (voltage plane or ground plane), physically adjacent to a signal routing
plane. Use of image planes provides a low impedance, shortest possible return path for RF currents. For a
USB board, the best image plane is the ground plane because it can be used for both analog and digital
circuits.
• Do not route traces so they cross from one plane to the other. This can cause a broken RF return path
resulting in an EMI radiating loop as shown in Figure 8-27. This is important for higher frequency or
repetitive signals. Therefore, on a multi-layer board, it is best to run all clock signals on the signal
plane above a solid ground plane.
• Avoid crossing the image power or ground plane boundaries with high-speed clock signal traces
immediately above or below the separated planes. This also holds true for the twisted pair signals (DP,
DM). Any unused area of the top and bottom signal layers of the PCB can be filled with copper that is
connected to the ground plane through vias.

areas on a circuit board. Therefore, the switching power regulator should be kept away from the DP/DM

USB 3.0 Board Design and Layout Guidelines
This section provides the timing specification for the USB3.0 (USB1 in the device) interface as a PCB
design and manufacturing specification. The design rules constrain PCB trace length, PCB trace skew,
signal integrity, cross-talk, and signal timing. TI has performed the simulation and system design work to
ensure the USB3.0 interface requirements are met. The design rules stated within this document are
targeted at DEVICE mode electrical compliance. HOST mode and/or systems that do not include the 3m
USB cable and far-end 11-inch PCB trace required by DEVICE mode compliance testing may not need
the complete list of optimizations shown in this document; however, applying these optimizations to HOST
mode systems will lead to optimal DEVICE mode performance.

USB 3.0 General routing rules
Some general routing guidelines regarding USB 3.0:
• Avoid crossing splits reference plane(s).
• Shorter trace length is preferred.
• Minimize the via usage and layer transition
• Keep large spacing between TX and RX pairs.
• Intra-lane delay mismatch between DP and DM less than 1ps. Same for RXp and RXn.
• Distance between common mode filter (CMF) and ESD protection device should be as short as
possible
• Distance between ESD protection device and USB connector should be as short as possible.
• Distance between AC capacitors (TX only) and CMF should be as short as possible.
• USB 3.0 signals should always be routed over an adjacent ground plane.

specification. The design rules constrain PCB trace length, PCB trace skew, signal integrity, cross-talk,
and signal timing. TI has performed the simulation and system design work to ensure the HDMI interface
requirements are met. The design rules stated within this document are targeted at resolutions less than
or equal to 1080p60 with 8-bit color; deep color (10-bit) requires further signal integrity optimization.

3. Consumer Electronics Control (optional) for remote control of connected devices.
The DDC and CEC are low speed interfaces, so nothing special is required for PCB layout of these
signals.
The TMDS channels are high speed differential pairs and therefore require the most care in layout.
Specifications for TMDS layout are below.

SPRS956B – MARCH 2016 – REVISED JANUARY 2017
TMDS General Routing Guidelines
The TMDS signals are high speed differential pairs. Care must be taken in the PCB layout of these signals
to ensure good signal integrity.
The TMDS differential signal traces must be routed to achieve 100 Ohms (+/- 10%) differential impedance
and 60 ohms (+/-10%) single ended impedance. Single ended impedance control is required because
differential signals can’t be closely coupled on PCBs and therefore single ended impedance becomes
important.
These impedances are impacted by trace width, trace spacing, distance to reference planes, and dielectric
material. Verify with a PCB design tool that the trace geometry for both data signal pairs results in as
close to 60 ohms impedance traces as possible. For best accuracy, work with your PCB fabricator to
ensure this impedance is met.
In general, closely coupled differential signal traces are not an advantage on PCBs. When differential
signals are closely coupled, tight spacing and width control is necessary. Very small width and spacing
variations affect impedance dramatically, so tight impedance control can be more problematic to maintain
in production.
Loosely coupled PCB differential signals make impedance control much easier. Wider traces and spacing
make obstacle avoidance easier, and trace width variations don’t affect impedance as much, therefore it’s
easier to maintain accurate impedance over the length of the signal. The wider traces also show reduced
skin effect and therefore often result in better signal integrity.
Some general routing guidelines regarding TMDS:
• Avoid crossing splits reference plane(s).
• Shorter trace length is preferred.
• Distance between common mode filter (CMF) and ESD protection device should be as short as
possible
• Distance between ESD protection device and HDMI connector should be as short as possible.
Table 8-13 shows the routing specifications for the TMDS signals.

TPD5S115
The TPD5S115 is an integrated HDMI companion chip solution. The device provides a regulated 5 V
output (5VOUT) for sourcing the HDMI power line. The TPD5S115 exceeds the IEC61000-4-2 (Level 4)
ESD protection level.
8.5.4.4
HDMI ESD Protection Device (Required)
Interfaces that connect to a cable such as HDMI generally require more ESD protection than can be built
into the processor’s outputs. Therefore this HDMI interface requires the use of an ESD protection chip to
provide adequate ESD.
When selecting an ESD protection chip, choose the lowest capacitance ESD protection available to
minimize signal degradation. In no case should be ESD protection circuit capacitance be more than 5pF.
TI manufactures these devices that provide ESD protection for HDMI signals such as the TPDxE05U06.

PCIe Board Design and Layout Guidelines
The PCIe interface on the device provides support for a 5.0 Gbps lane with polarity inversion.

PCIe Connections and Interface Compliance
The PCIe interface on the device is compliant with the PCIe revision 2.0 specification. Please refer to the
PCIe specifications for all connections that are described in it. Those recommendations are more
descriptive and exhaustive than what is possible here.
The use of PCIe compatible bridges and switches is allowed for interfacing with more than one other
processor or PCIe device.

AC coupling capacitors are required on the transmit data pair. Table 8-21 shows the requirements for
these capacitors.

8.5.6.2.2 Routing Specifications
8.5.6.2.2.1 Impedance
The PCIe data signal traces must be routed to achieve 100-Ω (±10%) differential impedance and 60-Ω
(±10%) single-ended impedance. The single-ended impedance is required because differential signals are
extremely difficult to closely couple on PCBs and, therefore, single-ended impedance becomes important.
These requirements are the same as those recommended in the PCIe Motherboard Checklist 1.0
document, available from PCI-SIG (www.pcisig.com).
These impedances are impacted by trace width, trace spacing, distance between signals and referencing
planes, and dielectric material. Verify with a PCB design tool that the trace geometry for both data signal
pairs result in as close to 100-Ω differential impedance and 60-Ω single-ended impedance as possible. For
best accuracy, work with your PCB fabricator to ensure this impedance is met. See Table 8-23 below.
8.5.6.2.2.2 Differential Coupling
In general, closely coupled differential signal traces are not an advantage on PCBs. When differential
signals are closely coupled, tight spacing and width control is necessary. Very small width and spacing
variations affect impedance dramatically, so tight impedance control can be more problematic to maintain
in production. For PCBs with very tight space limitations (which are usually small) this can work, but for
most PCBs, the loosely coupled option is probably best.
Loosely coupled PCB differential signals make impedance control much easier. Wider traces and spacing
make obstacle avoidance easier (because each trace is not so fixed in position relative to the other), and
trace width variations don’t affect impedance as much, therefore it’s easier to maintain an accurate
impedance over the length of the signal. For longer routes, the wider traces also show reduced skin effect
and therefore often result in better signal integrity with a larger eye diagram opening.

Length matching should be done as close to the mismatch as possible.
8.5.6.3
LJCB_REFN/P Connections
A Common Refclk Rx Architecture is required to be used for the device PCIe interface. Specifically, two
modes of Common Refclk Rx Architecture are supported:
• External REFCLK Mode: An common external 100MHz clock source is distributed to both the Device
and the link partner
• Output REFCLK Mode: A 100MHz HCSL clock source is output by the device and used by the link
partner
In External REFCLK Mode, a high-quality, low-jitter, differential HCSL 100MHz clock source compliant to
the PCIe REFCLK AC Specifications should be provided on the Device’s ljcb_clkn / ljcb_clkp inputs.
Alternatively, an LVDS clock source can be used with the following additional requirements:
• External AC coupling capacitors described in Table 8-25 should be populated at the ljcb_clkn /
ljcb_clkp inputs.
• All termination requirements (ex. parallel 100ohm termination) from the clock source manufacturer
should be followed.
In Output REFCLK Mode, the 100MHz clock from the Device’s DPLL_PCIE_REF should be output on
the Device’s ljcb_clkn / ljcb_clkp pins and used as the HCSL REFCLK by the link partner. External nearside termination to ground described in Table 8-26 is required on both of the ljcb_clkn / ljcb_clkp outputs
in this mode.

8.5.7.1.1 General Guidelines
The general guidelines for the PCB differential lines are:
• Differential trace impedance Z0 = 100 Ω (minimum = 85 Ω, maximum = 115 Ω)
• Total conductor length from the Device package pins to the peripheral device package pins is 25 to 30
cm with common FR4 PCB and flex materials.
NOTE
Longer interconnect length can be supported at the expense of detailed simulations of the
complete link including driver and receiver models.
The general rule of thumb for the space S = 2 × W is not designated (see Figure 8-19, Guard Illustration).
It is because although the S = 2 × W rule is a good rule of thumb, it is not always the best solution. The
electrical performance will be checked with the frequency-domain specification. Even though the designer
does not follow the S = 2 × W rule, the differential lines are ok if the lines satisfy the frequency-domain
specification.
Because the MIPI signals are used for low-power, single-ended signaling in addition to their high-speed
differential implementation, the pairs must be loosely coupled.
8.5.7.1.2 Length Mismatch Guidelines
8.5.7.1.2.1 CSI2_0 and CSI2_1 MIPI CSI-2 (1.5 Gbps)

8.5.7.1.3 Frequency-domain Specification Guidelines
After the PCB design is finished, the S-parameters of the PCB differential lines will be extracted with a 3D
Maxwell Equation Solver such as the high-frequency structure simulator (HFSS) or equivalent, and
compared to the frequency-domain specification as defined in the section 7 of the MIPI Alliance
Specification for D-PHY Version v1-01-00_r0-03.
If the PCB lines satisfy the frequency-domain specification, the design is finished. Otherwise, the design
needs to be improved.

Clock Routing Guidelines
32-kHz Oscillator Routing
When designing the printed-circuit board:
• Keep the crystal as close as possible to the crystal pins X1 and X2.
• Keep the trace lengths short and small to reduce capacitor loading and prevent unwanted noise
pickup.
• Place a guard ring around the crystal and tie the ring to ground to help isolate the crystal from
unwanted noise pickup.
• Keep all signals out from beneath the crystal and the X1 and X2 pins to prevent noise coupling.
• Finally, an additional local ground plane on an adjacent PCB layer can be added under the crystal to
shield it from unwanted pickup from traces on other layers of the board. This plane must be isolated
from the regular PCB ground plane and tied to the GND pin of the RTC. The plane must not be any
larger than the perimeter of the guard ring. Make sure that this ground plane does not contribute to
significant capacitance (a few pF) between the signal line and ground on the connections that run from
X1 and X2 to the crystal.

Although the impedance of a ground plane is low it is, of course, not zero. Therefore, any noise current in
the ground plane causes a voltage drop in the ground. Figure 8-38 shows the grounding scheme for slow

help ensure good signaling performance, consider the following board design guidelines:
Avoid crossing splits in the power plane.
Minimize Vref noise.
Use the widest trace that is practical between decoupling capacitors and memory module.
Maintain a single reference.
Minimize ISI by keeping impedances matched.
Minimize crosstalk by isolating sensitive bits, such as strobes, and avoiding return path discontinuities.
Use proper low-pass filtering on the Vref pins.
Keep the stub length as short as possible.
Add additional spacing for on-clock and strobe nets to eliminate crosstalk.
Maintain a common ground reference for all bypass and decoupling capacitors.

DDR3 Interface Schematic
8.7.2.4.1 32-Bit DDR3 Interface
The DDR3 interface schematic varies, depending upon the width of the DDR3 devices used and the width
of the bus used (16 or 32 bits). General connectivity is straightforward and very similar. 16-bit DDR
devices look like two 8-bit devices. Figure 8-41 and Figure 8-42 show the schematic connections for 32-bit
interfaces using x16 devices.
8.7.2.4.2 16-Bit DDR3 Interface
Note that the 16-bit wide interface schematic is practically identical to the 32-bit interface (see Figure 8-41
and Figure 8-42); only the high-word DDR memories are removed and the unused DQS inputs are tied off.
When not using all or part of a DDR interface, the proper method of handling the unused pins is to tie off
the ddrx_dqsi pins to ground via a 1k-Ω resistor and to tie off the ddrx_dqsni pins to the corresponding
vdds_ddrx supply via a 1k-Ω resistor. This needs to be done for each byte not used. Although these
signals have internal pullups and pulldowns, external pullups and pulldowns provide additional protection
against external electrical noise causing activity on the signals.
The vdds_ddrx and ddrx_vref0 power supply pins need to be connected to their respective power supplies
even if ddrx is not being used. All other DDR interface pins can be left unconnected. Note that the
supported modes for use of the DDR EMIF are 32-bits wide, 16-bits wide, or not used.

(1) Ground reference layers are preferred over power reference layers. Be sure to include bypass caps to accommodate reference layer
return current as the trace routes switch routing layers.
(2) No traces should cross reference plane cuts within the DDR routing region. High-speed signal traces crossing reference plane cuts
create large return current paths which can lead to excessive crosstalk and EMI radiation.
(3) Reference planes are to be directly adjacent to the signal plane to minimize the size of the return current loop.
(4) An 18-mil pad assumes Via Channel is the most economical BGA escape. A 20-mil pad may be used if additional layers are available
for power routing. An 18-mil pad is required for minimum layer count escape.
(5) Z is the nominal singled-ended impedance selected for the PCB specified by PS9.

Placement
Figure 8-43 shows the required placement for the processor as well as the DDR3 devices. The
dimensions for this figure are defined in Table 8-34. The placement does not restrict the side of the PCB
on which the devices are mounted. The ultimate purpose of the placement is to limit the maximum trace
lengths and allow for proper routing space. For a 16-bit DDR memory system, the high-word DDR3
devices are omitted from the placement.

8.7.2.8
DDR3 Keepout Region
The region of the PCB used for DDR3 circuitry must be isolated from other signals. The DDR3 keepout
region is defined for this purpose and is shown in Figure 8-44. The size of this region varies with the
placement and DDR routing. Additional clearances required for the keepout region are shown in Table 834. Non-DDR3 signals should not be routed on the DDR signal layers within the DDR3 keepout region.
Non-DDR3 signals may be routed in the region, provided they are routed on layers separated from the
DDR signal layers by a ground layer. No breaks should be allowed in the reference ground layers in this
region. In addition, the 1.5-V DDR3 power plane should cover the entire keepout region. Also note that the
two signals from the DDR3 controller should be separated from each other by the specification in Table 834 (see KOD37).

Bulk bypass capacitors are required for moderate speed bypassing of the DDR3 and other circuitry.
Table 8-35 contains the minimum numbers and capacitance required for the bulk bypass capacitors. Note

(1) These devices should be placed near the devices they are bypassing, but preference should be given to the placement of the highspeed (HS) bypass capacitors and DDR3 signal routing.
8.7.2.10 High-Speed Bypass Capacitors
High-speed (HS) bypass capacitors are critcal for proper DDR3 interface operation. It is particularly
important to minimize the parasitic series inductance of the HS bypass capacitors, processor/DDR power,
and processor/DDR ground connections. Table 8-36 contains the specification for the HS bypass
capacitors as well as for the power connections on the PCB. Generally speaking, it is good to:
1. Fit as many HS bypass capacitors as possible.
2. Minimize the distance from the bypass cap to the pins/balls being bypassed.
3. Use the smallest physical sized capacitors possible with the highest capacitance readily available.
4. Connect the bypass capacitor pads to their vias using the widest traces possible and using the largest
hole size via possible.
5. Minimize via sharing. Note the limites on via sharing shown in Table 8-36.

(9) An HS bypass capacitor may share a via with a DDR device mounted on the same side of the PCB. A wide trace should be used for the
connection and the length from the capacitor pad to the DDR device pad should be less than 150 mils.
(10) Up to a total of two pairs of DDR power/ground balls may share a via.
(11) The capacitor recommendations in this data manual reflect only the needs of this processor. Please see the memory vendor’s
guidelines for determining the appropriate decoupling capacitor arrangement for the memory device itself.
(12) For more information, see Section 8.3, Core Power Domains.
8.7.2.10.1 Return Current Bypass Capacitors
Use additional bypass capacitors if the return current reference plane changes due to DDR3 signals
hopping from one signal layer to another. The bypass capacitor here provides a path for the return current
to hop planes along with the signal. As many of these return current bypass capacitors should be used as
possible. Because these are returns for signal current, the signal via size may be used for these
capacitors.

8.7.2.12 DDR3 Signal Termination
Signal terminators are required for the CK and ADDR_CTRL net classes. The data lines are terminated by
ODT and, thus, the PCB traces should be unterminated. Detailed termination specifications are covered in
the routing rules in the following sections.
8.7.2.13 VREF_DDR Routing
ddrx_vref0 (VREF) is used as a reference by the input buffers of the DDR3 memories as well as the
processor. VREF is intended to be half the DDR3 power supply voltage and is typically generated with the
DDR3 VDDS and VTT power supply. It should be routed as a nominal 20-mil wide trace with 0.1 µF
bypass capacitors near each device connection. Narrowing of VREF is allowed to accommodate routing
congestion.

8.7.2.14 VTT
Like VREF, the nominal value of the VTT supply is half the DDR3 supply voltage. Unlike VREF, VTT is
expected to source and sink current, specifically the termination current for the ADDR_CTRL net class
Thevinen terminators. VTT is needed at the end of the address bus and it should be routed as a power
sub-plane. VTT should be bypassed near the terminator resistors.
8.7.2.15 CK and ADDR_CTRL Topologies and Routing Definition
The CK and ADDR_CTRL net classes are routed similarly and are length matched to minimize skew
between them. CK is a bit more complicated because it runs at a higher transition rate and is differential.
The following subsections show the topology and routing for various DDR3 configurations for CK and
ADDR_CTRL. The figures in the following subsections define the terms for the routing specification
detailed in Table 8-39.
8.7.2.15.1 Four DDR3 Devices
Four DDR3 devices are supported on the DDR EMIF consisting of four x8 DDR3 devices arranged as one
bank (CS). These four devices may be mounted on a single side of the PCB, or may be mirrored in two
pairs to save board space at a cost of increased routing complexity and parts on the backside of the PCB.

8.7.2.16 Data Topologies and Routing Definition
No matter the number of DDR3 devices used, the data line topology is always point to point, so its
definition is simple.
Care should be taken to minimize layer transitions during routing. If a layer transition is necessary, it is
better to transition to a layer using the same reference plane. If this cannot be accommodated, ensure
there are nearby ground vias to allow the return currents to transition between reference planes if both
reference planes are ground or vdds_ddr. Ensure there are nearby bypass capacitors to allow the return
currents to transition between reference planes if one of the reference planes is ground. The goal is to
minimize the size of the return current loops.
8.7.2.16.1 DQS and DQ/DM Topologies, Any Number of Allowed DDR3 Devices
DQS lines are point-to-point differential, and DQ/DM lines are point-to-point singled ended. Figure 8-61

8.7.2.17 Routing Specification
8.7.2.17.1 CK and ADDR_CTRL Routing Specification
Skew within the CK and ADDR_CTRL net classes directly reduces setup and hold margin and, thus, this
skew must be controlled. The only way to practically match lengths on a PCB is to lengthen the shorter
traces up to the length of the longest net in the net class and its associated clock. A metric to establish
this maximum length is Manhattan distance. The Manhattan distance between two points on a PCB is the
length between the points when connecting them only with horizontal or vertical segments. A reasonable
trace route length is to within a percentage of its Manhattan distance. CACLM is defined as Clock Address
Control Longest Manhattan distance.

Given the clock and address pin locations on the processor and the DDR3 memories, the maximum
possible Manhattan distance can be determined given the placement. Figure 8-65 and Figure 8-66 show
this distance for four loads and two loads, respectively. It is from this distance that the specifications on
the lengths of the transmission lines for the address bus are determined. CACLM is determined similarly
for other address bus configurations; that is, it is based on the longest net of the CK/ADDR_CTRL net
class. For CK and ADDR_CTRL routing, these specifications are contained in Table 8-39.

It is very likely that the longest CK/ADDR_CTRL Manhattan distance will be for Address Input 8 (A8) on the DDR3
memories. CACLM is based on the longest Manhattan distance due to the device placement. Verify the net class that
satisfies this criteria and use as the baseline for CK/ADDR_CTRL skew matching and length control.
The length of shorter CK/ADDR_CTRL stubs as well as the length of the terminator stub are not included in this
length calculation. Non-included lengths are grayed out in the figure.
Assuming A8 is the longest, CALM = CACLMY + CACLMX + 300 mils.
The extra 300 mils allows for routing down lower than the DDR3 memories and returning up to reach A8.

(1) Max value is based upon conservative signal integrity approach. This value could be extended only if detailed signal integrity analysis of
rice time and fall time confirms desired operation.
(2) The use of vias should be minimized.
(3) Additional bypass capacitors are required when using the DDR_1V5 plane as the reference plane to allow the return current to jump
between the DDR_1V5 plane and the ground plane when the net class switches layers at a via.
(4) Non-mirrored configuration (all DDR3 memories on same side of PCB).
(5) Mirrored configuration (one DDR3 device on top of the board and one DDR3 device on the bottom).
(6) While this length can be increased for convenience, its length should be minimized.
(7) ADDR_CTRL net class only (not CK net class). Minimizing this skew is recommended, but not required.
(8) CK net class only.
(9) Center-to-center spacing is allowed to fall to minimum 2w for up to 1250 mils of routed length.
(10) The ADDR_CTRL net class of the other DDR EMIF is considered other DDR3 trace spacing.
(11) CK spacing set to ensure proper differential impedance.
(12) The most important thing to do is control the impedance so inadvertent impedance mismatches are not created. Generally speaking,
center-to-center spacing should be either 2w or slightly larger than 2w to achieve a differential impedance equal to twice the singleended
impedance, Zo.
(13) Source termination (series resistor at driver) is specifically not allowed.
(14) Termination values should be uniform across the net class.
(15) Via count difference may increase by 1 only if accurate 3-D modeling of the signal flight times – including accurately modeled signal
propagation through vias – has been applied to ensure all segment skew maximums are not exceeded.
8.7.2.17.2 DQS and DQ Routing Specification
Skew within the DQS and DQ/DM net classes directly reduces setup and hold margin and thus this skew
must be controlled. The only way to practically match lengths on a PCB is to lengthen the shorter traces
up to the length of the longest net in the net class and its associated clock. As with CK and ADDR_CTRL,
a reasonable trace route length is to within a percentage of its Manhattan distance. DQLMn is defined as
DQ Longest Manhattan distance n, where n is the byte number. For a 32-bit interface, there are four
DQLMs, DQLM0-DQLM3. Likewise, for a 16-bit interface, there are two DQLMs, DQLM0-DQLM1.
NOTE
It is not required, nor is it recommended, to match the lengths across all bytes. Length
matching is only required within each byte.
Given the DQS and DQ/DM pin locations on the processor and the DDR3 memories, the maximum
possible Manhattan distance can be determined given the placement. Figure 8-67 shows this distance for
four loads. It is from this distance that the specifications on the lengths of the transmission lines for the
data bus are determined. For DQS and DQ/DM routing, these specifications are contained in Table 8-40.

9 Device and Documentation Support
TI offers an extensive line of development tools, including methods to evaluate the performance of the
processors, generate code, develop algorithm implementations, and fully integrate and debug software
and hardware modules as listed below.
9.1
Device Nomenclature
To designate the stages in the product development cycle, TI assigns prefixes to the part numbers of all
microprocessors (MPUs) and support tools. Each device has one of three prefixes: X, P, or null (no prefix)
(for example, DRA72x). Texas Instruments recommends two of three possible prefix designators for its
support tools: TMDX and TMDS. These prefixes represent evolutionary stages of product development
from engineering prototypes (TMDX) through fully qualified production devices and tools (TMDS).
Device development evolutionary flow:
X
Experimental device that is not necessarily representative of the final device's electrical
specifications and may not use production assembly flow.
P
Prototype device that is not necessarily the final silicon die and may not necessarily meet
final electrical specifications.
null
Production version of the silicon die that is fully qualified.
Support tool development evolutionary flow:
TMDX
Development-support product that has not yet completed Texas Instruments internal
qualification testing.
TMDS
Fully-qualified development-support product.
X and P devices and TMDX development-support tools are shipped against the following disclaimer:
"Developmental product is intended for internal evaluation purposes."
Production devices and TMDS development-support tools have been characterized fully, and the quality
and reliability of the device have been demonstrated fully. TI's standard warranty applies.
Predictions show that prototype devices (X or P) have a greater failure rate than the standard production
devices. Texas Instruments recommends that these devices not be used in any production system
because their expected end-use failure rate still is undefined. Only qualified production devices are to be
used.
For orderable part numbers of DRA72x devices in the ABC package type, see the Package Option
Addendum of this document, the TI website (www.ti.com), or contact your TI sales representative.
For additional description of the device nomenclature markings on the die, see the Silicon Errata (literature
number SPRZ426 ).

Electrostatic Discharge Caution
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
