does not fully comply with the maximum AC ratings and device protection
guideline outlined in the PCI rev. 2.2 standard (section 4.2.2.3).
Figure 2. Overshoot/Undershoot Voltage for GVDD/OVDD/LVDD/BVDD/TVDD
The core voltage must always be provided at nominal 1.1 V. Voltage to the processor interface I/Os are
provided through separate sets of supply pins and must be provided at the voltages shown in Table 2. The
input voltage threshold scales with respect to the associated I/O supply voltage. OVDD and LVDD based
receivers are simple CMOS I/O circuits and satisfy appropriate LVCMOS type specifications. The DDR
SDRAM interface uses a single-ended differential receiver referenced the externally supplied MVREF
signal (nominally set to GVDD/2) as is appropriate for the SSTL2 electrical signaling standard.

Notes:

2. The drive strength of the PCI interface is determined by the setting of the PCI_GNT1 signal at reset.
3. The drive strength of the DDR interface in half-strength mode is at Tj = 105°C and at GVDD (min).
2.2
Power Sequencing
The device requires its power rails to be applied in a specific sequence in order to ensure proper device
operation. These requirements are as follows for power-up:
1. VDD, AVDD_n, BVDD, LVDD, OVDD, SVDD, TVDD, XVDD
2. GVDD
All supplies must be at their stable values within 50 ms.
NOTE
Items on the same line have no ordering requirement with respect to one
another. Items on separate lines must be ordered sequentially such that
voltage rails on a previous step must reach 90% of their value before the
voltage rails on the current step reach 10% of theirs.
NOTE
In order to guarantee MCKE low during power-up, the above sequencing for
GVDD is required. If there is no concern about any of the DDR signals being
in an indeterminate state during power-up, then the sequencing for GVDD is
not required.

Power Characteristics
NOTE
From a system standpoint, if any of the I/O power supplies ramp prior to the
VDD core supply, the I/Os associated with that I/O supply may drive a logic
one or zero during power-up, and extra current may be drawn by the device.

SYSCLK jitter
Notes:
1. Caution: The CCB clock to SYSCLK ratio and e500 core to CCB clock ratio settings must be chosen such that the resulting
SYSCLK frequency, e500 (core) frequency, and CCB clock frequency do not exceed their respective maximum or minimum
operating frequencies.Refer to Section 20.2, “CCB/SYSCLK PLL Ratio,” and Section 20.3, “e500 Core PLL Ratio,” for ratio
settings.
2. Rise and fall times for SYSCLK are measured at 0.6 and 2.7 V.
3. Timing is guaranteed by design and characterization.
4. This represents the total input jitter—short term and long term—and is guaranteed by design.
5. The SYSCLK driver’s closed loop jitter bandwidth should be <500 kHz at –20 dB. The bandwidth must be set low to allow
cascade-connected PLL-based devices to track SYSCLK drivers with the specified jitter.
6. This parameter has been adjusted slower according to the workaround for device erratum GEN 13.
7. For spread spectrum clocking. Guidelines are + 0% to –1% down spread at modulation rate between 20 and 60 kHz on
SYSCLK.
8. System with operating core frequency less than 1200 MHz must limit SYSCLK frequency to 100 MHz maximum.
4.2
Real Time Clock Timing
The RTC input is sampled by the platform clock (CCB clock). The output of the sampling latch is then
used as an input to the counters of the PIC and the TimeBase unit of the e500. There is no jitter
specification. The minimum pulse width of the RTC signal should be greater than 2x the period of the CCB
clock. That is, minimum clock high time is 2 × tCCB, and minimum clock low time is 2 × tCCB. There is
no minimum RTC frequency; RTC may be grounded if not needed.

2. Timing is guaranteed by design and characterization.
3. EC_GTX_CLK125 is used to generate the GTX clock TSECn_GTX_CLK for the eTSEC transmitter with 2% degradation.
EC_GTX_CLK125 duty cycle can be loosened from 47/53% as long as the PHY device can tolerate the duty cycle generated
by the TSECn_ GTX_CLK. See Section 8.2.6, “RGMII and RTBI AC Timing Specifications,” for duty cycle for 10Base-T and
100Base-T reference clock.

PCI/PCI-X Reference Clock Timing
When the PCI/PCI-X controller is configured for asynchronous operation, the reference clock for the

Platform to FIFO Restrictions
Note the following FIFO maximum speed restrictions based on platform speed.
For FIFO GMII mode:
FIFO TX/RX clock frequency ≤ platform clock frequency/4.2
For example, if the platform frequency is 533 MHz, the FIFO TX/RX clock frequency should be no more
than 127 MHz.
For FIFO encoded mode:
FIFO TX/RX clock frequency ≤ platform clock frequency/4.2
For example, if the platform frequency is 533 MHz, the FIFO TX/RX clock frequency should be no more
than 167 MHz.

Platform Frequency Requirements for PCI-Express and Serial
RapidIO
The CCB clock frequency must be considered for proper operation of the high-speed PCI-Express and
Serial RapidIO interfaces as described below.
For proper PCI Express operation, the CCB clock frequency must be greater than:
527 MHz × (PCI-Express link width)
8
See MPC8548ERM, Rev. 2, PowerQUICC III Integrated Processor Family Reference Manual,
Section 18.1.3.2, “Link Width,” for PCI Express interface width details.
For proper serial RapidIO operation, the CCB clock frequency must be greater than:
2 × (0.80) × (Serial RapidIO interface frequency) × (Serial RapidIO link width)

Notes:
1. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for
inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. Output hold time can be read as DDR timing
(DD) from the rising or falling edge of the reference clock (KH or KL) until the output went invalid (AX or DX). For example,
tDDKHAS symbolizes DDR timing (DD) for the time tMCK memory clock reference (K) goes from the high (H) state until outputs
(A) are setup (S) or output valid time. Also, tDDKLDX symbolizes DDR timing (DD) for the time tMCK memory clock reference
(K) goes low (L) until data outputs (D) are invalid (X) or data output hold time.
2. All MCK/MCK referenced measurements are made from the crossing of the two signals ±0.1 V.
3. ADDR/CMD includes all DDR SDRAM output signals except MCK/MCK, MCS, and MDQ/MECC/MDM/MDQS.
4. Note that tDDKHMH follows the symbol conventions described in note 1. For example, tDDKHMH describes the DDR timing (DD)
from the rising edge of the MCK[n] clock (KH) until the MDQS signal is valid (MH). tDDKHMH can be modified through control
of the MDQS override bits (called WR_DATA_DELAY) in the TIMING_CFG_2 register. This is typically set to the same delay
as in DDR_SDRAM_CLK_CNTL[CLK_ADJUST]. The timing parameters listed in the table assume that these 2 parameters
have been set to the same adjustment value. See the MPC8548E PowerQUICC™ III Integrated Processor Reference Manual
for a description and understanding of the timing modifications enabled by use of these bits.

FIFO, GMII, MII, TBI, RGMII, RMII, and RTBI AC Timing
Specifications
The AC timing specifications for FIFO, GMII, MII, TBI, RGMII, RMII, and RTBI are presented in this
section.
8.2.1
FIFO AC Specifications
The basis for the AC specifications for the eTSEC’s FIFO modes is the double data rate RGMII and RTBI
specifications, since they have similar performances and are described in a source-synchronous fashion
like FIFO modes. However, the FIFO interface provides deliberate skew between the transmitted data and
source clock in GMII fashion.
When the eTSEC is configured for FIFO modes, all clocks are supplied from external sources to the
relevant eTSEC interface. That is, the transmit clock must be applied to the eTSECn’s TSECn_TX_CLK,
while the receive clock must be applied to pin TSECn_RX_CLK. The eTSEC internally uses the transmit
clock to synchronously generate transmit data and outputs an echoed copy of the transmit clock back out
onto the TSECn_GTX_CLK pin (while transmit data appears on TSECn_TXD[7:0], for example). It is
intended that external receivers capture eTSEC transmit data using the clock on TSECn_GTX_CLK as a
source- synchronous timing reference. Typically, the clock edge that launched the data can be used, since
the clock is delayed by the eTSEC to allow acceptable set-up margin at the receiver. Note that there is
relationship between the maximum FIFO speed and the platform speed. For more information see
Section 4.5, “Platform to FIFO Restrictions.”

Notes:
1. The symbols used for timing specifications follow the pattern t(first two letters of functional block)(signal)(state)(reference)(state) for inputs
and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tGTKHDV symbolizes GMII transmit timing
(GT) with respect to the tGTX clock reference (K) going to the high state (H) relative to the time date input signals (D) reaching
the valid state (V) to state or setup time. Also, tGTKHDX symbolizes GMII transmit timing (GT) with respect to the tGTX clock
reference (K) going to the high state (H) relative to the time date input signals (D) going invalid (X) or hold time. Note that, in
general, the clock reference symbol representation is based on three letters representing the clock of a particular functional.
For example, the subscript of tGTX represents the GMII(G) transmit (TX) clock. For rise and fall times, the latter convention is
used with the appropriate letter: R (rise) or F (fall).

When the eTSEC is configured for TBI modes, all clocks are supplied from external sources to the relevant
eTSEC interface. In single-clock TBI mode, when TBICON[CLKSEL] = 1, a 125-MHz TBI receive clock
is supplied on the TSECn_RX_CLK pin (no receive clock is used on TSECn_TX_CLK in this mode,
whereas for the dual-clock mode this is the PMA1 receive clock). The 125-MHz transmit clock is applied

Notes:
1. In general, the clock reference symbol representation for this section is based on the symbols RGT to represent RGMII and
RTBI timing. For example, the subscript of tRGT represents the TBI (T) receive (RX) clock. Note also that the notation for rise
(R) and fall (F) times follows the clock symbol that is being represented. For symbols representing skews, the subscript is
skew (SK) followed by the clock that is being skewed (RGT).
2. This implies that PC board design requires clocks to be routed such that an additional trace delay of greater than 1.5 ns is
added to the associated clock signal.
3. For 10 and 100 Mbps, tRGT scales to 400 ns ± 40 ns and 40 ns ± 4 ns, respectively.
4. Duty cycle may be stretched/shrunk during speed changes or while transitioning to a received packet's clock domains as long
as the minimum duty cycle is not violated and stretching occurs for no more than three tRGT of the lowest speed transitioned
between.
5. Guaranteed by characterization.
6. In rev 1.0 silicon, due to errata, tSKRGT is -650 ps (min) and 650 ps (max). Refer to “eTSEC 10” in the device errata document.

Notes:
1. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for
inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tMDKHDX symbolizes management
data timing (MD) for the time tMDC from clock reference (K) high (H) until data outputs (D) are invalid (X) or data hold time.
Also, tMDDVKH symbolizes management data timing (MD) with respect to the time data input signals (D) reach the valid state
(V) relative to the tMDC clock reference (K) going to the high (H) state or setup time. For rise and fall times, the latter convention
is used with the appropriate letter: R (rise) or F (fall).
2. This parameter is dependent on the eTSEC system clock speed, which is half of the Platform Frequency (fCCB). The actual
ECn_MDC output clock frequency for a specific eTSEC port can be programmed by configuring the MgmtClk bit field of
MPC8548E’s MIIMCFG register, based on the platform (CCB) clock running for the device. The formula is: Platform Frequency
(CCB) ÷ (2 × Frequency Divider determined by MIICFG[MgmtClk] encoding selection). For example, if
MIICFG[MgmtClk] = 000 and the platform (CCB) is currently running at 533 MHz, fMDC = 533) ÷ (2 × 4 × 8) = 533) ÷ 64 =
8.3 MHz. That is, for a system running at a particular platform frequency (fCCB), the ECn_MDC output clock frequency can be
programmed between maximum fMDC = fCCB ÷ 64 and minimum fMDC = fCCB ÷ 448. Refer to MPC8572E reference manual’s
MIIMCFG register section for more detail.3.The maximum ECn_MDC output clock frequency is defined based on the
maximum platform frequency for MPC8548E (533 MHz) divided by 64, while the minimum ECn_MDC output clock frequency
is defined based on the minimum platform frequency for MPC8548E (333 MHz) divided by 448, following the formula
described in Note 2 above.
4. Guaranteed by design.
5. tCCB is the platform (CCB) clock period.

Notes:
1. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for
inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tLBIXKH1 symbolizes local bus
timing (LB) for the input (I) to go invalid (X) with respect to the time the tLBK clock reference (K) goes high (H), in this case for
clock one (1). Also, tLBKHOX symbolizes local bus timing (LB) for the tLBK clock reference (K) to go high (H), with respect to
the output (O) going invalid (X) or output hold time.
2. All timings are in reference to LSYNC_IN for PLL enabled and internal local bus clock for PLL bypass mode.
3. All signals are measured from BVDD/2 of the rising edge of LSYNC_IN for PLL enabled or internal local bus clock for PLL
bypass mode to 0.4 × BVDD of the signal in question for 3.3-V signaling levels.
4. Input timings are measured at the pin.
5. For purposes of active/float timing measurements, the Hi-Z or off state is defined to be when the total current delivered
through the component pin is less than or equal to the leakage current specification.
6. tLBOTOT is a measurement of the minimum time between the negation of LALE and any change in LAD. tLBOTOT is
programmed with the LBCR[AHD] parameter.
7. Maximum possible clock skew between a clock LCLK[m] and a relative clock LCLK[n]. Skew measured between
complementary signals at BV DD/2.

Notes:
1. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for
inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tLBIXKH1 symbolizes local bus
timing (LB) for the input (I) to go invalid (X) with respect to the time the tLBK clock reference (K) goes high (H), in this case for
clock one (1). Also, tLBKHOX symbolizes local bus timing (LB) for the tLBK clock reference (K) to go high (H), with respect to
the output (O) going invalid (X) or output hold time.
2. All timings are in reference to local bus clock for PLL bypass mode. Timings may be negative with respect to the local bus
clock because the actual launch and capture of signals is done with the internal launch/capture clock, which precedes LCLK
by tLBKHKT.
3. Maximum possible clock skew between a clock LCLK[m] and a relative clock LCLK[n]. Skew measured between
complementary signals at BV DD/2.
4. All signals are measured from BVDD/2 of the rising edge of local bus clock for PLL bypass mode to 0.4 × BV DD of the signal
in question for 3.3-V signaling levels.
5. Input timings are measured at the pin.
6. The value of tLBOTOT is the measurement of the minimum time between the negation of LALE and any change in LAD.
7. For purposes of active/float timing measurements, the Hi-Z or off state is defined to be when the total current delivered
through the component pin is less than or equal to the leakage current specification.
8. Guaranteed by characterization.
9. Guaranteed by design.

NOTE
In PLL bypass mode, LCLK[n] is the inverted version of the internal clock
with the delay of tLBKHKT. In this mode, signals are launched at the rising edge
of the internal clock and are captured at falling edge of the internal clock
with the exception of LGTA/LUPWAIT (which is captured on the rising
edge of the internal clock).

Notes:
1. All outputs are measured from the midpoint voltage of the falling/rising edge of tTCLK to the midpoint of the signal in question.
The output timings are measured at the pins. All output timings assume a purely resistive 50-Ω load (see Figure 29).
Time-of-flight delays must be added for trace lengths, vias, and connectors in the system.
2. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for
inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tJTDVKH symbolizes JTAG device
timing (JT) with respect to the time data input signals (D) reaching the valid state (V) relative to the tJTG clock reference (K)
going to the high (H) state or setup time. Also, tJTDXKH symbolizes JTAG timing (JT) with respect to the time data input signals
(D) went invalid (X) relative to the tJTG clock reference (K) going to the high (H) state. Note that, in general, the clock reference
symbol representation is based on three letters representing the clock of a particular functional. For rise and fall times, the
latter convention is used with the appropriate letter: R (rise) or F (fall).
3. TRST is an asynchronous level sensitive signal. The setup time is for test purposes only.
4. Non-JTAG signal input timing with respect to tTCLK.
5. Non-JTAG signal output timing with respect to tTCLK.

Notes:
1. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state)(reference)(state) for
inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tI2DVKH symbolizes I2C timing (I2)
with respect to the time data input signals (D) reach the valid state (V) relative to the tI2C clock reference (K) going to the high
(H) state or setup time. Also, tI2SXKL symbolizes I2C timing (I2) for the time that the data with respect to the start condition
(S) went invalid (X) relative to the tI2C clock reference (K) going to the low (L) state or hold time. Also, tI2PVKH symbolizes I2C
timing (I2) for the time that the data with respect to the stop condition (P) reaching the valid state (V) relative to the tI2C clock
reference (K) going to the high (H) state or setup time. For rise and fall times, the latter convention is used with the appropriate
letter: R (rise) or F (fall).
2. As a transmitter, the MPC8548E provides a delay time of at least 300 ns for the SDA signal (refer to the VIH(min) of the SCL
signal) to bridge the undefined region of the falling edge of SCL to avoid unintended generation of Start or Stop condition.
When MPC8548E acts as the I2C bus master while transmitting, MPC8548E drives both SCL and SDA. As long as the load
on SCL and SDA are balanced, MPC8548E would not cause unintended generation of Start or Stop condition. Therefore,
the 300 ns SDA output delay time is not a concern. If, under some rare condition, the 300 ns SDA output delay time is required
for MPC8548E as transmitter, the following setting is recommended for the FDR bit field of the I2CFDR register to ensure
both the desired I2C SCL clock frequency and SDA output delay time are achieved, assuming that the desired I2C SCL clock
frequency is 400 kHz and the Digital Filter Sampling Rate Register (I2CDFSRR) is programmed with its default setting of
0x10 (decimal 16):
I2C source clock frequency

For the detail of I2C frequency calculation, refer to Freescale Application Note AN2919, Determining the I2C Frequency
Divider Ratio for SCL. Note that the I2C source clock frequency is half of the CCB clock frequency for MPC8548E.
3. The maximum tI2DXKL has only to be met if the device does not stretch the LOW period (tI2CL) of the SCL signal.

inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tPCIVKH symbolizes PCI/PCI-X
timing (PC) with respect to the time the input signals (I) reach the valid state (V) relative to the SYSCLK clock, tSYS, reference
(K) going to the high (H) state or setup time. Also, tPCRHFV symbolizes PCI/PCI-X timing (PC) with respect to the time hard
reset (R) went high (H) relative to the frame signal (F) going to the valid (V) state.
2. See the timing measurement conditions in the PCI 2.2 Local Bus Specifications.
3. All PCI signals are measured from OVDD/2 of the rising edge of SYSCLK or PCI_CLKn to 0.4 × OVDD of the signal in question
for 3.3-V PCI signaling levels.
4. For purposes of active/float timing measurements, the Hi-Z or off state is defined to be when the total current delivered
through the component pin is less than or equal to the leakage current specification.
5. Input timings are measured at the pin.
6. The timing parameter tSYS indicates the minimum and maximum CLK cycle times for the various specified frequencies. The
system clock period must be kept within the minimum and maximum defined ranges. For values see Section 20, “Clocking.”
7. The setup and hold time is with respect to the rising edge of HRESET.
8. The timing parameter tPCRHFV is a minimum of 10 clocks rather than the minimum of 5 clocks in the PCI 2.2 Local Bus
Specifications.
9. The reset assertion timing requirement for HRESET is 100 μs.
10.Guaranteed by characterization.

16 High-Speed Serial Interfaces (HSSI)
The MPC8548E features one Serializer/Deserializer (SerDes) interface to be used for high-speed serial
interconnect applications. The SerDes interface can be used for PCI Express and/or serial RapidIO data
transfers.
This section describes the common portion of SerDes DC electrical specifications, which is the DC
requirement for SerDes reference clocks. The SerDes data lane’s transmitter and receiver reference circuits
are also shown.
16.1
Signal Terms Definition
The SerDes utilizes differential signaling to transfer data across the serial link. This section defines terms
used in the description and specification of differential signals.
Figure 38 shows how the signals are defined. For illustration purpose, only one SerDes lane is used for the
description. The figure shows a waveform for either a transmitter output (SD_TX and SD_TX) or a
receiver input (SD_RX and SD_RX). Each signal swings between A volts and B volts where A > B.
Using this waveform, the definitions are as follows. To simplify the illustration, the following definitions
assume that the SerDes transmitter and receiver operate in a fully symmetrical differential signaling
environment.
• Single-ended swing
The transmitter output signals and the receiver input signals SD_TX, SD_TX, SD_RX and SD_RX

each have a peak-to-peak swing of A – B volts. This is also referred as each signal wire’s
single-ended swing.
Differential output voltage, VOD (or differential output swing):
The differential output voltage (or swing) of the transmitter, VOD, is defined as the difference of
the two complimentary output voltages: VSD_TX – VSD_TX. The VOD value can be either positive
or negative.
Differential input voltage, VID (or differential input swing):
The differential input voltage (or swing) of the receiver, VID, is defined as the difference of the two
complimentary input voltages: VSD_RX – VSD_RX. The VID value can be either positive or
negative.
Differential peak voltage, VDIFFp
The peak value of the differential transmitter output signal or the differential receiver input signal
is defined as differential peak voltage, VDIFFp = |A – B| volts.
Differential peak-to-peak, VDIFFp-p
Because the differential output signal of the transmitter and the differential input signal of the
receiver each range from A – B to –(A – B) volts, the peak-to-peak value of the differential
transmitter output signal or the differential receiver input signal is defined as differential
peak-to-peak voltage, VDIFFp-p = 2 × VDIFFp = 2 × |(A – B)| volts, which is twice of differential
swing in amplitude, or twice of the differential peak. For example, the output differential
peak-to-peak voltage can also be calculated as VTX-DIFFp-p = 2 × |VOD|.
Common mode voltage, Vcm
The common mode voltage is equal to one half of the sum of the voltages between each conductor
of a balanced interchange circuit and ground. In this example, for SerDes output, Vcm_out =
VSD_TX + VSD_TX = (A + B)/2, which is the arithmetic mean of the two complimentary output
voltages within a differential pair. In a system, the common mode voltage may often differ from
one component’s output to the other’s input. Sometimes, it may be even different between the
receiver input and driver output circuits within the same component. It is also referred to as the DC
offset.

To illustrate these definitions using real values, consider the case of a CML (current mode logic)
transmitter that has a common mode voltage of 2.25 V and each of its outputs, TD and TD, has a swing

High-Speed Serial Interfaces (HSSI)
that goes between 2.5 and 2.0 V. Using these values, the peak-to-peak voltage swing of each signal (TD or
TD) is 500 mVp-p, which is referred as the single-ended swing for each signal. In this example, since the
differential signaling environment is fully symmetrical, the transmitter output’s differential swing (VOD)
has the same amplitude as each signal’s single-ended swing. The differential output signal ranges between
500 and –500 mV, in other words, VOD is 500 mV in one phase and –500 mV in the other phase. The peak
differential voltage (VDIFFp) is 500 mV. The peak-to-peak differential voltage (VDIFFp-p) is 1000 mVp-p.
16.2
SerDes Reference Clocks
The SerDes reference clock inputs are applied to an internal PLL whose output creates the clock used by
the corresponding SerDes lanes. The SerDes reference clocks inputs are SD_REF_CLK and
SD_REF_CLK for PCI Express and serial RapidIO.
The following sections describe the SerDes reference clock requirements and some application
information.
16.2.1
SerDes Reference Clock Receiver Characteristics
Figure 39 shows a receiver reference diagram of the SerDes reference clocks.
• The supply voltage requirements for XVDD_SRDS2 are specified in Table 1 and Table 2.
• SerDes Reference clock receiver reference circuit structure:
— The SD_REF_CLK and SD_REF_CLK are internally AC-coupled differential inputs as shown
in Figure 39. Each differential clock input (SD_REF_CLK or SD_REF_CLK) has a 50-Ω
termination to SGND_SRDSn (xcorevss) followed by on-chip AC-coupling.
— The external reference clock driver must be able to drive this termination.
— The SerDes reference clock input can be either differential or single-ended. Refer to the
differential mode and single-ended mode description below for further detailed requirements.
• The maximum average current requirement that also determines the common mode voltage range:
— When the SerDes reference clock differential inputs are DC coupled externally with the clock
driver chip, the maximum average current allowed for each input pin is 8 mA. In this case, the
exact common mode input voltage is not critical as long as it is within the range allowed by the
maximum average current of 8 mA (refer to the following bullet for more detail), since the
input is AC-coupled on-chip.
— This current limitation sets the maximum common mode input voltage to be less than 0.4 V
(0.4 V/50 = 8 mA) while the minimum common mode input level is 0.1 V above
SGND_SRDSn (xcorevss). For example, a clock with a 50/50 duty cycle can be produced by
a clock driver with output driven by its current source from 0 to 16 mA (0–0.8 V), such that
each phase of the differential input has a single-ended swing from 0 V to 800 mV with the
common mode voltage at 400 mV.
— If the device driving the SD_REF_CLK and SD_REF_CLK inputs cannot drive 50 Ω to
SGND_SRDSn (xcorevss) DC, or it exceeds the maximum input current limitations, then it
must be AC-coupled off-chip.
• The input amplitude requirement:
— This requirement is described in detail in the following sections.

16.2.2
DC Level Requirement for SerDes Reference Clocks
The DC level requirement for the MPC8548E SerDes reference clock inputs is different depending on the
signaling mode used to connect the clock driver chip and SerDes reference clock inputs as described
below:
• Differential mode
— The input amplitude of the differential clock must be between 400 and 1600 mV differential
peak-peak (or between 200 and 800 mV differential peak). In other words, each signal wire of
the differential pair must have a single-ended swing less than 800 mV and greater than 200 mV.
This requirement is the same for both external DC- or AC-coupled connection.
— For external DC-coupled connection, as described in Section 16.2.1, “SerDes Reference Clock
Receiver Characteristics,” the maximum average current requirements sets the requirement for
average voltage (common mode voltage) to be between 100 and 400 mV. Figure 40 shows the
SerDes reference clock input requirement for DC-coupled connection scheme.
— For external AC-coupled connection, there is no common mode voltage requirement for the
clock driver. Since the external AC-coupling capacitor blocks the DC level, the clock driver
and the SerDes reference clock receiver operate in different command mode voltages. The
SerDes reference clock receiver in this connection scheme has its common mode voltage set to
SGND_SRDSn. Each signal wire of the differential inputs is allowed to swing below and above
the command mode voltage (SGND_SRDSn). Figure 41 shows the SerDes reference clock
input requirement for AC-coupled connection scheme.
• Single-ended mode
— The reference clock can also be single-ended. The SD_REF_CLK input amplitude
(single-ended swing) must be between 400 and 800 mV peak-to-peak (from Vmin to Vmax) with
SD_REF_CLK either left unconnected or tied to ground.
— The SD_REF_CLK input average voltage must be between 200 and 400 mV. Figure 42 shows
the SerDes reference clock input requirement for single-ended signaling mode.
— To meet the input amplitude requirement, the reference clock inputs might need to be DC- or
AC-coupled externally. For the best noise performance, the reference of the clock could be DC-

Interfacing with Other Differential Signaling Levels
With on-chip termination to SGND_SRDSn (xcorevss), the differential reference clocks inputs are
HCSL (high-speed current steering logic) compatible DC-coupled.
Many other low voltage differential type outputs like LVDS (low voltage differential signaling) can
be used but may need to be AC-coupled due to the limited common mode input range allowed (100
to 400 mV) for DC-coupled connection.
LVPECL outputs can produce signal with too large amplitude and may need to be DC-biased at
clock driver output first, then followed with series attenuation resistor to reduce the amplitude, in
addition to AC-coupling.

NOTE
Figure 43 through Figure 46 below are for conceptual reference only. Due
to the fact that clock driver chip's internal structure, output impedance, and
termination requirements are different between various clock driver chip
manufacturers, it is very possible that the clock circuit reference designs
provided by clock driver chip vendor are different from what is shown
below. They might also vary from one vendor to the other. Therefore,
Freescale Semiconductor can neither provide the optimal clock driver
reference circuits, nor guarantee the correctness of the following clock
driver connection reference circuits. The system designer is recommended
to contact the selected clock driver chip vendor for the optimal reference
circuits with the MPC8548E SerDes reference clock receiver requirement
provided in this document.
Figure 43 shows the SerDes reference clock connection reference circuits for HCSL type clock driver. It
assumes that the DC levels of the clock driver chip is compatible with MPC8548E SerDes reference clock
input’s DC requirement.

Figure 45 shows the SerDes reference clock connection reference circuits for LVPECL type clock driver.
Since LVPECL driver’s DC levels (both common mode voltages and output swing) are incompatible with
the MPC8548E SerDes reference clock input’s DC requirement, AC-coupling has to be used. Figure 45
assumes that the LVPECL clock driver’s output impedance is 50 Ω. R1 is used to DC-bias the LVPECL
outputs prior to AC-coupling. Its value could be ranged from 140 to 240 Ω depending on the clock driver
vendor’s requirement. R2 is used together with the SerDes reference clock receiver’s 50-Ω termination
resistor to attenuate the LVPECL output’s differential peak level such that it meets the MPC8548E SerDes
reference clock’s differential input amplitude requirement (between 200 and 800 mV differential peak).
For example, if the LVPECL output’s differential peak is 900 mV and the desired SerDes reference clock
input amplitude is selected as 600 mV, the attenuation factor is 0.67, which requires R2 = 25 Ω. Consult a
clock driver chip manufacturer to verify whether this connection scheme is compatible with a particular
clock driver chip.

AC Requirements for SerDes Reference Clocks
The clock driver selected should provide a high quality reference clock with low phase noise and
cycle-to-cycle jitter. Phase noise less than 100 kHz can be tracked by the PLL and data recovery loops and
is less of a problem. Phase noise above 15 MHz is filtered by the PLL. The most problematic phase noise
occurs in the 1–15 MHz range. The source impedance of the clock driver should be 50 Ω to match the
transmission line and reduce reflections which are a source of noise to the system.
The detailed AC requirements of the SerDes reference clocks is defined by each interface protocol based
on application usage. Refer to the following sections for detailed information:
• Section 17.2, “AC Requirements for PCI Express SerDes Clocks”
• Section 18.2, “AC Requirements for Serial RapidIO SD_REF_CLK and SD_REF_CLK”
16.2.4.1
Spread Spectrum Clock
SD_REF_CLK/SD_REF_CLK are designed to work with a spread spectrum clock (+0% to –0.5%
spreading at 30–33 kHz rate is allowed), assuming both ends have same reference clock. For better results,
a source without significant unintended modulation should be used.

Transmitter Compliance Eye Diagrams
The TX eye diagram in Figure 48 is specified using the passive compliance/test measurement load (see
Figure 50) in place of any real PCI Express interconnect +RX component.
There are two eye diagrams that must be met for the transmitter. Both eye diagrams must be aligned in
time using the jitter median to locate the center of the eye diagram. The different eye diagrams differ in
voltage depending whether it is a transition bit or a de-emphasized bit. The exact reduced voltage level of
the de-emphasized bit is always relative to the transition bit.
The eye diagram must be valid for any 250 consecutive UIs.

Skew across all lanes on a Link. This includes

as well as any delay differences arising from the
interconnect itself.
Notes:
1. No test load is necessarily associated with this value.
2. Specified at the measurement point and measured over any 250 consecutive UIs. The test load in Figure 50 should be used
as the RX device when taking measurements (also refer to the receiver compliance eye diagram shown in Figure 49). If the
clocks to the RX and TX are not derived from the same reference clock, the TX UI recovered from 3500 consecutive UI must
be used as a reference for the eye diagram.
3. A TRX-EYE = 0.40 UI provides for a total sum of 0.60 UI deterministic and random jitter budget for the transmitter and
interconnect collected any 250 consecutive UIs. The TRX-EYE-MEDIAN-to-MAX-JITTER specification ensures a jitter distribution
in which the median and the maximum deviation from the median is less than half of the total. UI jitter budget collected over
any 250 consecutive TX UIs. It should be noted that the median is not the same as the mean. The jitter median describes
the point in time where the number of jitter points on either side is approximately equal as opposed to the averaged time
value. If the clocks to the RX and TX are not derived from the same reference clock, the TX UI recovered from 3500
consecutive UI must be used as the reference for the eye diagram.
4. The receiver input impedance shall result in a differential return loss greater than or equal to 15 dB with the D+ line biased
to 300 mV and the D– line biased to –{300 mV and a common mode return loss greater than or equal to 6 dB (no bias
required) over a frequency range of 50 MHz to 1.25 GHz. This input impedance requirement applies to all valid input levels.
The reference impedance for return loss measurements for is 50 Ω to ground for both the D+ and D– line (that is, as measured
by a vector network analyzer with 50-Ω probes—see Figure 50). Note: that the series capacitors CTX is optional for the return
loss measurement.
5. Impedance during all LTSSM states. When transitioning from a fundamental reset to detect (the initial state of the LTSSM)
there is a 5 ms transition time before receiver termination values must be met on all unconfigured lanes of a port.
6. The RX DC common mode Impedance that exists when no power is present or fundamental reset is asserted. This helps
ensure that the receiver detect circuit does not falsely assume a receiver is powered on when it is not. This term must be
measured at 300 mV above the RX ground.
7. It is recommended that the recovered TX UI is calculated using all edges in the 3500 consecutive UI interval with a fit
algorithm using a minimization merit function. Least squares and median deviation fits have worked well with experimental
and simulated data.
17.5
Receiver Compliance Eye Diagrams
The RX eye diagram in Figure 49 is specified using the passive compliance/test measurement load (see
Figure 50) in place of any real PCI Express RX component.
Note: In general, the minimum receiver eye diagram measured with the compliance/test measurement load
(see Figure 50) is larger than the minimum receiver eye diagram measured over a range of systems at the
input receiver of any real PCI Express component. The degraded eye diagram at the input receiver is due
to traces internal to the package as well as silicon parasitic characteristics which cause the real PCI Express
component to vary in impedance from the compliance/test measurement load. The input receiver eye
diagram is implementation specific and is not specified. RX component designer should provide additional
margin to adequately compensate for the degraded minimum receiver eye diagram (shown in Figure 49)
expected at the input receiver based on some adequate combination of system simulations and the return
loss measured looking into the RX package and silicon. The RX eye diagram must be aligned in time using
the jitter median to locate the center of the eye diagram.

18 Serial RapidIO
This section describes the DC and AC electrical specifications for the RapidIO interface of the
MPC8548E, for the LP-Serial physical layer. The electrical specifications cover both single- and
multiple-lane links. Two transmitters (short and long run) and a single receiver are specified for each of
three baud rates, 1.25, 2.50, and 3.125 GBaud.
Two transmitter specifications allow for solutions ranging from simple board-to-board interconnect to
driving two connectors across a backplane. A single receiver specification is given that accepts signals
from both the short- and long-run transmitter specifications.
The short-run transmitter should be used mainly for chip-to-chip connections on either the same
printed-circuit board or across a single connector. This covers the case where connections are made to a
mezzanine (daughter) card. The minimum swings of the short-run specification reduce the overall power
used by the transceivers.
The long-run transmitter specifications use larger voltage swings that are capable of driving signals across
backplanes. This allows a user to drive signals across two connectors and a backplane. The specifications
allow a distance of at least 50 cm at all baud rates.
All unit intervals are specified with a tolerance of ±100 ppm. The worst case frequency difference between
any transmit and receive clock is 200 ppm.
To ensure interoperability between drivers and receivers of different vendors and technologies, AC
coupling at the receiver input must be used.

Signal Definitions
LP-serial links use differential signaling. This section defines terms used in the description and
specification of differential signals. Figure 51 shows how the signals are defined. The figures show
waveforms for either a transmitter output (TD and TD) or a receiver input (RD and RD). Each signal
swings between A volts and B volts where A > B. Using these waveforms, the definitions are as follows:
1. The transmitter output signals and the receiver input signals TD, TD, RD, and RD each have a
peak-to-peak swing of A – B volts.
2. The differential output signal of the transmitter, VOD, is defined as VTD – VTD.
3. The differential input signal of the receiver, VID, is defined as VRD – VRD.
4. The differential output signal of the transmitter and the differential input signal of the receiver
each range from A – B to –(A – B) volts.
5. The peak value of the differential transmitter output signal and the differential receiver input
signal is A – B volts.
6. The peak-to-peak value of the differential transmitter output signal and the differential receiver
input signal is 2 × (A – B) volts.

Differential Peak-to-Peak = 2 × (A – B)
Figure 51. Differential Peak–Peak Voltage of Transmitter or Receiver
To illustrate these definitions using real values, consider the case of a CML (current mode logic)
transmitter that has a common mode voltage of 2.25 V and each of its outputs, TD and TD, has a swing
that goes between 2.5 and 2.0 V. Using these values, the peak-to-peak voltage swing of the signals TD and
TD is 500 mVp-p. The differential output signal ranges between 500 and –500 mV. The peak differential
voltage is 500 mV. The peak-to-peak differential voltage is 1000 mVp-p.
18.4
Equalization
With the use of high-speed serial links, the interconnect media causes degradation of the signal at the
receiver. Effects such as inter-symbol interference (ISI) or data dependent jitter are produced. This loss can
be large enough to degrade the eye opening at the receiver beyond what is allowed in the specification. To
negate a portion of these effects, equalization can be used. The most common equalization techniques that
can be used are:
• A passive high pass filter network placed at the receiver. This is often referred to as passive
equalization.
• The use of active circuits in the receiver. This is often referred to as adaptive equalization.

Explanatory Note on Transmitter and Receiver Specifications
AC electrical specifications are given for transmitter and receiver. Long- and short-run interfaces at three
baud rates (a total of six cases) are described.
The parameters for the AC electrical specifications are guided by the XAUI electrical interface specified
in Clause 47 of IEEE 802.3ae-2002.
XAUI has similar application goals to Serial RapidIO, as described in Section 8.1. The goal of this
standard is that electrical designs for Serial RapidIO can reuse electrical designs for XAUI, suitably
modified for applications at the baud intervals and reaches described herein.
18.6
Transmitter Specifications
LP-serial transmitter electrical and timing specifications are stated in the text and tables of this section.
The differential return loss, S11, of the transmitter in each case shall be better than:
• –10 dB for (baud frequency)/10 < Freq(f) < 625 MHz, and
• –10 dB + 10log(f/625 MHz) dB for 625 MHz ≤ Freq(f) ≤ baud frequency
The reference impedance for the differential return loss measurements is 100-Ω resistive. Differential
return loss includes contributions from on-chip circuitry, chip packaging, and any off-chip components
related to the driver. The output impedance requirement applies to all valid output levels.
It is recommended that the 20%–80% rise/fall time of the transmitter, as measured at the transmitter output,
in each case have a minimum value 60 ps.
It is recommended that the timing skew at the output of an LP-serial transmitter between the two signals
that comprise a differential pair not exceed 25 ps at 1.25 GB, 20 ps at 2.50 GB, and 15 ps at 3.125 GB.

Receiver Eye Diagrams
For each baud rate at which an LP-serial receiver is specified to operate, the receiver shall meet the
corresponding bit error rate specification (Table 66, Table 67, and Table 68) when the eye pattern of the
receiver test signal (exclusive of sinusoidal jitter) falls entirely within the unshaded portion of the receiver
input compliance mask shown in Figure 54 with the parameters specified in Table 69. The eye pattern of
the receiver test signal is measured at the input pins of the receiving device with the device replaced with
a 100-Ω ± 5% differential resistive load.

Measurement and Test Requirements
Since the LP-serial electrical specification are guided by the XAUI electrical interface specified in
Clause 47 of IEEE Std. 802.3ae-2002, the measurement and test requirements defined here are similarly
guided by Clause 47. In addition, the CJPAT test pattern defined in Annex 48A of IEEE Std. 802.3ae-2002
MPC8548E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 8
Freescale Semiconductor
85
Serial RapidIO
is specified as the test pattern for use in eye pattern and jitter measurements. Annex 48B of IEEE Std.
802.3ae-2002 is recommended as a reference for additional information on jitter test methods.
18.9.1
Eye Template Measurements
For the purpose of eye template measurements, the effects of a single-pole high pass filter with a 3 dB point
at (baud frequency)/1667 is applied to the jitter. The data pattern for template measurements is the
continuous jitter test pattern (CJPAT) defined in Annex 48A of IEEE 802.3ae. All lanes of the LP-serial
link shall be active in both the transmit and receive directions, and opposite ends of the links shall use
asynchronous clocks. Four lane implementations shall use CJPAT as defined in Annex 48A. Single lane
implementations shall use the CJPAT sequence specified in Annex 48A for transmission on lane 0. The
amount of data represented in the eye shall be adequate to ensure that the bit error ratio is less than 10–12.
The eye pattern shall be measured with AC coupling and the compliance template centered at 0 V
differential. The left and right edges of the template shall be aligned with the mean zero crossing points of
the measured data eye. The load for this test shall be 100-Ω resistive ± 5% differential to 2.5 GHz.
18.9.2
Jitter Test Measurements
For the purpose of jitter measurement, the effects of a single-pole high pass filter with a 3 dB point at (baud
frequency)/1667 is applied to the jitter. The data pattern for jitter measurements is the Continuous Jitter test
pattern (CJPAT) pattern defined in Annex 48A of IEEE 802.3ae. All lanes of the LP-serial link shall be
active in both the transmit and receive directions, and opposite ends of the links shall use asynchronous
clocks. Four lane implementations shall use CJPAT as defined in Annex 48A. Single lane implementations
shall use the CJPAT sequence specified in Annex 48A for transmission on lane 0. Jitter shall be measured
with AC coupling and at 0 V differential. Jitter measurement for the transmitter (or for calibration of a jitter
tolerance setup) shall be performed with a test procedure resulting in a BER curve such as that described
in Annex 48B of IEEE 802.3ae.
18.9.3
Transmit Jitter
Transmit jitter is measured at the driver output when terminated into a load of 100 Ω resistive ± 5%
differential to 2.5 GHz.
18.9.4
Jitter Tolerance
Jitter tolerance is measured at the receiver using a jitter tolerance test signal. This signal is obtained by first
producing the sum of deterministic and random jitter defined in Section 18.7, “Receiver Specifications,”
and then adjusting the signal amplitude until the data eye contacts the 6 points of the minimum eye opening
of the receive template shown in Figure 54 and Table 69. Note that for this to occur, the test signal must
have vertical waveform symmetry about the average value and have horizontal symmetry (including jitter)
about the mean zero crossing. Eye template measurement requirements are as defined above. Random
jitter is calibrated using a high pass filter with a low frequency corner at 20 MHz and a 20 dB/decade
roll-off below this. The required sinusoidal jitter specified in Section 18.7, “Receiver Specifications,” is
then added to the signal and the test load is replaced by the receiver being tested.

Notes:
1. All multiplexed signals are listed only once and do not re-occur. For example, LCS5/DMA_REQ2 is listed only once in the
local bus controller section, and is not mentioned in the DMA section even though the pin also functions as DMA_REQ2.
2. Recommend a weak pull-up resistor (2–10 kΩ) be placed on this pin to OVDD.
3. A valid clock must be provided at POR if TSEC4_TXD[2] is set = 1.
4. This pin is an open drain signal.
5. This pin is a reset configuration pin. It has a weak internal pull-up P-FET which is enabled only when the processor is in the
reset state. This pull-up is designed such that it can be overpowered by an external 4.7-kΩ pull-down resistor. However, if the
signal is intended to be high after reset, and if there is any device on the net which might pull down the value of the net at
reset, then a pullup or active driver is needed.
6. Treat these pins as no connects (NC) unless using debug address functionality.
7. The value of LA[28:31] during reset sets the CCB clock to SYSCLK PLL ratio. These pins require 4.7-kΩ pull-up or pull-down
resistors. See Section 20.2, “CCB/SYSCLK PLL Ratio.”
8. The value of LALE, LGPL2, and LBCTL at reset set the e500 core clock to CCB clock PLL ratio. These pins require 4.7-kΩ
pull-up or pull-down resistors. See the Section 20.3, “e500 Core PLL Ratio.”
9. Functionally, this pin is an output, but structurally it is an I/O because it either samples configuration input during reset or
because it has other manufacturing test functions. This pin therefore is described as an I/O for boundary scan.
10.This pin functionally requires a pull-up resistor, but during reset it is a configuration input that controls 32- vs. 64-bit PCI
operation. Therefore, it must be actively driven low during reset by reset logic if the device is to be configured to be a 64-bit
PCI device. Refer to the PCI Specification.
11.This output is actively driven during reset rather than being three-stated during reset.
12.These JTAG pins have weak internal pull-up P-FETs that are always enabled.
13.These pins are connected to the VDD/GND planes internally and may be used by the core power supply to improve tracking
and regulation.
14.Internal thermally sensitive resistor.
15.No connections should be made to these pins if they are not used.
16.These pins are not connected for any use.
17.PCI specifications recommend that a weak pull-up resistor (2–10 kΩ) be placed on the higher order pins to OVDD when using
64-bit buffer mode (pins PCI_AD[63:32] and PCI1_C_BE[7:4]).
19.If this pin is connected to a device that pulls down during reset, an external pull-up is required to drive this pin to a safe state
during reset.
20.This pin is only an output in FIFO mode when used as Rx flow control.
24.Do not connect.

Notes
25.These are test signals for factory use only and must be pulled up (100 Ω–1 kΩ) to OVDD for normal machine operation.
26.Independent supplies derived from board VDD.
27.Recommend a pull-up resistor (~1 kΩ) be placed on this pin to OVDD.
29. The following pins must NOT be pulled down during power-on reset: TSEC3_TXD[3], TSEC4_TXD3/TSEC3_TXD7,
HRESET_REQ, TRIG_OUT/READY/QUIESCE, MSRCID[2:4], ASLEEP.
30.This pin requires an external 4.7-kΩ pull-down resistor to prevent PHY from seeing a valid transmit enable before it is actively
driven.
31.This pin is only an output in eTSEC3 FIFO mode when used as Rx flow control.
32.These pins should be connected to XVDD.
33.TSEC2_TXD1, TSEC2_TX_ER are multiplexed as cfg_dram_type[0:1]. They must be valid at power-up, even before
HRESET assertion.
34.These pins should be pulled to ground through a 300-Ω (±10%) resistor.
35.When a PCI block is disabled, either the POR config pin that selects between internal and external arbiter must be pulled
down to select external arbiter if there is any other PCI device connected on the PCI bus, or leave the PCIn_AD pins as ‘no
connect’ or terminated through 2–10 kΩ pull-up resistors with the default of internal arbiter if the PCIn_AD pins are not
connected to any other PCI device. The PCI block drives the PCIn_AD pins if it is configured to be the PCI arbiter—through
POR config pins—irrespective of whether it is disabled via the DEVDISR register or not. It may cause contention if there is
any other PCI device connected on the bus.
36.MDIC0 is grounded through an 18.2-Ω precision 1% resistor and MDIC1 is connected to GVDD through an 18.2-Ω precision
1% resistor. These pins are used for automatic calibration of the DDR IOs.
38.These pins should be left floating.
39. If PCI1 or PCI2 is configured as PCI asynchronous mode, a valid clock must be provided on pin PCI1_CLK or PCI2_CLK.
Otherwise the processor will not boot up.
40.These pins should be connected to GND.
101.This pin requires an external 4.7-kΩ resistor to GND.
102.For Rev. 2.x silicon, DMA_DACK[0:1] must be 0b11 during POR configuration; for rev. 1.x silicon, the pin values during POR
configuration are don’t care.
103.If these pins are not used as GPINn (general-purpose input), they should be pulled low (to GND) or high (to LVDD) through
2–10 kΩ resistors.
104.These should be pulled low to GND through 2–10 kΩ resistors if they are not used.
105.These should be pulled low or high to LVDD through 2–10 kΩ resistors if they are not used.
106.For rev. 2.x silicon, DMA_DACK[0:1] must be 0b10 during POR configuration; for rev. 1.x silicon, the pin values during POR
configuration are don’t care.
107.For rev. 2.x silicon, DMA_DACK[0:1] must be 0b01 during POR configuration; for rev. 1.x silicon, the pin values during POR
configuration are don’t care.
108.For rev. 2.x silicon, DMA_DACK[0:1] must be 0b11 during POR configuration; for rev. 1.x silicon, the pin values during POR
configuration are don’t care.
109.This is a test signal for factory use only and must be pulled down (100 Ω – 1 kΩ) to GND for normal machine operation.
110.These pins should be pulled high to OVDD through 2–10 kΩ resistors.
111.If these pins are not used as GPINn (general-purpose input), they should be pulled low (to GND) or high (to OVDD) through
2–10 kΩ resistors.
112.This pin must not be pulled down during POR configuration.
113.These should be pulled low or high to OVDD through 2–10 kΩ resistors.

20.2
CCB/SYSCLK PLL Ratio
The CCB clock is the clock that drives the e500 core complex bus (CCB), and is also called the platform
clock. The frequency of the CCB is set using the following reset signals, as shown in Table 81:
• SYSCLK input signal
• Binary value on LA[28:31] at power up
Note that there is no default for this PLL ratio; these signals must be pulled to the desired values. Also note
that the DDR data rate is the determining factor in selecting the CCB bus frequency, since the CCB
frequency must equal the DDR data rate.
For specifications on the PCI_CLK, refer to the PCI 2.2 Specification.

Heat Sink Solution
Every system application has different conditions that the thermal management solution must solve. As
such, providing a recommended heat sink has not been found to be very useful. When a heat sink is chosen,
give special consideration to the mounting technique. Mounting the heat sink to the printed-circuit board
is the recommended procedure using a maximum of 10 lbs force (45 Newtons) perpendicular to the
package and board. Clipping the heat sink to the package is not recommended.
22 System Design Information
This section provides electrical design recommendations for successful application of the MPC8548E.
22.1
System Clocking
This device includes five PLLs, as follows:
1. The platform PLL generates the platform clock from the externally supplied SYSCLK input. The
frequency ratio between the platform and SYSCLK is selected using the platform PLL ratio
configuration bits as described in Section 20.2, “CCB/SYSCLK PLL Ratio.”
2. The e500 core PLL generates the core clock as a slave to the platform clock. The frequency ratio
between the e500 core clock and the platform clock is selected using the e500 PLL ratio
configuration bits as described in Section 20.3, “e500 Core PLL Ratio.”
3. The PCI PLL generates the clocking for the PCI bus.
4. The local bus PLL generates the clock for the local bus.
5. There is a PLL for the SerDes block.
22.2
PLL Power Supply Filtering
Each of the PLLs listed above is provided with power through independent power supply pins
(AVDD_PLAT, AVDD_CORE, AVDD_PCI, AVDD_LBIU, and AVDD_SRDS, respectively). The AVDD
level should always be equivalent to VDD, and preferably these voltages are derived directly from VDD
through a low frequency filter scheme such as the following.
MPC8548E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 8
128
Freescale Semiconductor
System Design Information
There are a number of ways to reliably provide power to the PLLs, but the recommended solution is to
provide independent filter circuits per PLL power supply as illustrated in Figure 56, one to each of the
AVDD pins. By providing independent filters to each PLL the opportunity to cause noise injection from
one PLL to the other is reduced.
This circuit is intended to filter noise in the PLLs resonant frequency range from a 500 kHz to 10 MHz
range. It should be built with surface mount capacitors with minimum Effective Series Inductance (ESL).
Consistent with the recommendations of Dr. Howard Johnson in High Speed Digital Design: A Handbook
of Black Magic (Prentice Hall, 1993), multiple small capacitors of equal value are recommended over a
single large value capacitor.
Each circuit should be placed as close as possible to the specific AVDD pin being supplied to minimize
noise coupled from nearby circuits. It should be possible to route directly from the capacitors to the AVDD
pin, which is on the periphery of the footprint, without the inductance of vias.
Figure 56 through Figure 58 shows the PLL power supply filter circuits.

The AVDD_SRDS signal provides power for the analog portions of the SerDes PLL. To ensure stability of
the internal clock, the power supplied to the PLL is filtered using a circuit similar to the one shown in
following figure. For maximum effectiveness, the filter circuit is placed as closely as possible to the
AVDD_SRDS ball to ensure it filters out as much noise as possible. The ground connection should be near
the AVDD_SRDS ball. The 0.003-µF capacitor is closest to the ball, followed by the two 2.2 µF capacitors,
and finally the 1 Ω resistor to the board supply plane. The capacitors are connected from AVDD_SRDS to
the ground plane. Use ceramic chip capacitors with the highest possible self-resonant frequency. All traces
should be kept short, wide and direct.

22.3
Decoupling Recommendations
Due to large address and data buses, and high operating frequencies, the device can generate transient
power surges and high frequency noise in its power supply, especially while driving large capacitive loads.
This noise must be prevented from reaching other components in the MPC8548E system, and the device
itself requires a clean, tightly regulated source of power. Therefore, it is recommended that the system
designer place at least one decoupling capacitor at each VDD, TVDD, BVDD, OVDD, GVDD, and LVDD pin
of the device. These decoupling capacitors should receive their power from separate VDD, TVDD, BVDD,
OVDD, GVDD, LVDD, and GND power planes in the PCB, utilizing short low impedance traces to
minimize inductance. Capacitors must be placed directly under the device using a standard escape pattern
as much as possible. If some caps are to be placed surrounding the part it should be routed with large trace
to minimize the inductance.
These capacitors should have a value of 0.1 µF. Only ceramic SMT (surface mount technology) capacitors
should be used to minimize lead inductance, preferably 0402 or 0603 sizes.
In addition, it is recommended that there be several bulk storage capacitors distributed around the PCB,
feeding the VDD, TVDD, BVDD, OVDD, GVDD, and LVDD, planes, to enable quick recharging of the
smaller chip capacitors. These bulk capacitors should have a low ESR (equivalent series resistance) rating
to ensure the quick response time necessary. They should also be connected to the power and ground
planes through two vias to minimize inductance. Suggested bulk capacitors—100–330 µF (AVX TPS
tantalum or Sanyo OSCON). However, customers should work directly with their power regulator vendor
for best values, types and quantity of bulk capacitors.
22.4
SerDes Block Power Supply Decoupling Recommendations
The SerDes block requires a clean, tightly regulated source of power (SVDD and XVDD) to ensure low
jitter on transmit and reliable recovery of data in the receiver. An appropriate decoupling scheme is
outlined below.
Only surface mount technology (SMT) capacitors should be used to minimize inductance. Connections
from all capacitors to power and ground should be done with multiple vias to further reduce inductance.
• First, the board should have at least 10 × 10-nF SMT ceramic chip capacitors as close as possible
to the supply balls of the device. Where the board has blind vias, these capacitors should be placed
MPC8548E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 8
130
Freescale Semiconductor
System Design Information
•
•
22.5
directly below the chip supply and ground connections. Where the board does not have blind vias,
these capacitors should be placed in a ring around the device as close to the supply and ground
connections as possible.
Second, there should be a 1-µF ceramic chip capacitor from each SerDes supply (SVDD and
XVDD) to the board ground plane on each side of the device. This should be done for all SerDes
supplies.
Third, between the device and any SerDes voltage regulator there should be a 10-µF, low
equivalent series resistance (ESR) SMT tantalum chip capacitor and a 100-µF, low ESR SMT
tantalum chip capacitor. This should be done for all SerDes supplies.
Connection Recommendations
To ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal
level. All unused active low inputs should be tied to VDD, TVDD, BVDD, OVDD, GVDD, and LVDD, as
required. All unused active high inputs should be connected to GND. All NC (no-connect) signals must
remain unconnected. Power and ground connections must be made to all external VDD, TVDD, BVDD,
OVDD, GVDD, LVDD, and GND pins of the device.
22.6
Pull-Up and Pull-Down Resistor Requirements
The MPC8548E requires weak pull-up resistors (2–10 kΩ is recommended) on open drain type pins
including I2C pins and PIC (interrupt) pins.
Correct operation of the JTAG interface requires configuration of a group of system control pins as
demonstrated in Figure 62. Care must be taken to ensure that these pins are maintained at a valid deasserted
state under normal operating conditions as most have asynchronous behavior and spurious assertion gives
unpredictable results.
The following pins must not be pulled down during power-on reset: TSEC3_TXD[3], HRESET_REQ,
TRIG_OUT/READY/QUIESCE, MSRCID[2:4], ASLEEP. The DMA_DACK[0:1], and TEST_SEL/
TEST_SEL pins must be set to a proper state during POR configuration. Refer to the pinlist table of the
individual device for more details
Refer to the PCI 2.2 specification for all pull ups required for PCI.
22.7
Output Buffer DC Impedance
The MPC8548E drivers are characterized over process, voltage, and temperature. For all buses, the driver
is a push-pull single-ended driver type (open drain for I2C).
To measure Z0 for the single-ended drivers, an external resistor is connected from the chip pad to OVDD
or GND. Then, the value of each resistor is varied until the pad voltage is OVDD/2 (see Figure 60). The
output impedance is the average of two components, the resistances of the pull-up and pull-down devices.
When data is held high, SW1 is closed (SW2 is open) and RP is trimmed until the voltage at the pad equals
OVDD/2. RP then becomes the resistance of the pull-up devices. RP and RN are designed to be close to each
other in value. Then, Z0 = (RP + RN)/2.

22.8
Configuration Pin Muxing
The MPC8548E provides the user with power-on configuration options which can be set through the use
of external pull-up or pull-down resistors of 4.7 kΩ on certain output pins (see customer visible
configuration pins). These pins are generally used as output only pins in normal operation.
While HRESET is asserted however, these pins are treated as inputs. The value presented on these pins
while HRESET is asserted, is latched when HRESET deasserts, at which time the input receiver is disabled
and the I/O circuit takes on its normal function. Most of these sampled configuration pins are equipped
with an on-chip gated resistor of approximately 20 kΩ. This value should permit the 4.7-kΩ resistor to pull
the configuration pin to a valid logic low level. The pull-up resistor is enabled only during HRESET (and
for platform/system clocks after HRESET deassertion to ensure capture of the reset value). When the input
receiver is disabled the pull-up is also, thus allowing functional operation of the pin as an output with
minimal signal quality or delay disruption. The default value for all configuration bits treated this way has
been encoded such that a high voltage level puts the device into the default state and external resistors are
needed only when non-default settings are required by the user.
Careful board layout with stubless connections to these pull-down resistors coupled with the large value
of the pull-down resistor should minimize the disruption of signal quality or speed for output pins thus
configured.

132
Freescale Semiconductor
System Design Information
The platform PLL ratio and e500 PLL ratio configuration pins are not equipped with these default pull-up
devices.
22.9
JTAG Configuration Signals
Correct operation of the JTAG interface requires configuration of a group of system control pins as
demonstrated in Figure 62. Care must be taken to ensure that these pins are maintained at a valid deasserted
state under normal operating conditions as most have asynchronous behavior and spurious assertion gives
unpredictable results.
Boundary-scan testing is enabled through the JTAG interface signals. The TRST signal is optional in the
IEEE 1149.1 specification, but it is provided on all processors built on Power Architecture technology. The
device requires TRST to be asserted during power-on reset flow to ensure that the JTAG boundary logic
does not interfere with normal chip operation. While the TAP controller can be forced to the reset state
using only the TCK and TMS signals, generally systems assert TRST during the power-on reset flow.
Simply tying TRST to HRESET is not practical because the JTAG interface is also used for accessing the
common on-chip processor (COP), which implements the debug interface to the chip.
The COP function of these processors allow a remote computer system (typically, a PC with dedicated
hardware and debugging software) to access and control the internal operations of the processor. The COP
interface connects primarily through the JTAG port of the processor, with some additional status
monitoring signals. The COP port requires the ability to independently assert HRESET or TRST in order
to fully control the processor. If the target system has independent reset sources, such as voltage monitors,
watchdog timers, power supply failures, or push-button switches, then the COP reset signals must be
merged into these signals with logic.
The arrangement shown in Figure 62 allows the COP port to independently assert HRESET or TRST,
while ensuring that the target can drive HRESET as well.
The COP interface has a standard header, shown in Figure 61, for connection to the target system, and is
based on the 0.025" square-post, 0.100" centered header assembly (often called a Berg header). The
connector typically has pin 14 removed as a connector key.
The COP header adds many benefits such as breakpoints, watchpoints, register and memory
examination/modification, and other standard debugger features. An inexpensive option can be to leave
the COP header unpopulated until needed.
There is no standardized way to number the COP header; so emulator vendors have issued many different
pin numbering schemes. Some COP headers are numbered top-to-bottom then left-to-right, while others
use left-to-right then top-to-bottom. Still others number the pins counter-clockwise from pin 1 (as with an
IC). Regardless of the numbering scheme, the signal placement recommended in Figure 61 is common to
all known emulators.
22.9.1
Termination of Unused Signals
Freescale recommends the following connections, when the JTAG interface and COP header are not used:
• TRST should be tied to HRESET through a 0 kΩ isolation resistor so that it is asserted when the
system reset signal (HRESET) is asserted, ensuring that the JTAG scan chain is initialized during
the power-on reset flow. Freescale recommends that the COP header be designed into the system

as shown in Figure 62. If this is not possible, the isolation resistor allows future access to TRST in
case a JTAG interface may need to be wired onto the system in future debug situations.

Notes:

in order to fully control the processor as shown here.
2. Populate this with a 10−Ω resistor for short-circuit/current-limiting protection.
3. The KEY location (pin 14) is not physically present on the COP header.
4. Although pin 12 is defined as a No-Connect, some debug tools may use pin 12 as an additional GND pin for
improved signal integrity.
5. This switch is included as a precaution for BSDL testing. The switch should be closed to position A during BSDL
testing to avoid accidentally asserting the TRST line. If BSDL testing is not being performed, this switch should be
closed to position B.
6. Asserting SRESET causes a machine check interrupt to the e500 core.

22.10 Guidelines for High-Speed Interface Termination
This section provides the guidelines for high-speed interface termination when the SerDes interface is
entirely unused and when it is partly unused.
22.10.1 SerDes Interface Entirely Unused
If the high-speed SerDes interface is not used at all, the unused pin should be terminated as described in
this section.
The following pins must be left unconnected (float):
• SD_TX[7:0]
• SD_TX[7:0]
• Reserved pins T22, T23, M20, M21
The following pins must be connected to GND:
• SD_RX[7:0]
• SD_RX[7:0]
• SD_REF_CLK
• SD_REF_CLK
NOTE
It is recommended to power down the unused lane through SRDSCR1[0:7]
register (offset = 0xE_0F08) (This prevents the oscillations and holds the
receiver output in a fixed state.) that maps to SERDES lane 0 to lane 7
accordingly.
Pins V28 and M26 must be tied to XVDD. Pins V27 and M25 must be tied to GND through a 300-Ω
resistor.
In Rev 2.0 silicon, POR configuration pin cfg_srds_en on TSEC4_TXD[2]/TSEC3_TXD[6] can be used
to power down SerDes block.
22.10.2 SerDes Interface Partly Unused
If only part of the high-speed SerDes interface pins are used, the remaining high-speed serial I/O pins
should be terminated as described in this section.
The following pins must be left unconnected (float) if not used:
• SD_TX[7:0]
• SD_TX[7:0]
• Reserved pins: T22, T23, M20, M21
The following pins must be connected to GND if not used:
• SD_RX[7:0]
• SD_RX[7:0]
• SD_REF_CLK

register (offset = 0xE_0F08) (this prevents the oscillations and holds the

accordingly.
Pins V28 and M26 must be tied to XVDD. Pins V27 and M25 must be tied to GND through a 300-Ω
resistor.
22.11 Guideline for PCI Interface Termination
PCI termination if PCI 1 or PCI 2 is not used at all.
Option 1
If PCI arbiter is enabled during POR:
• All AD pins are driven to the stable states after POR. Therefore, all ADs pins can be floating.
• All PCI control pins can be grouped together and tied to OVDD through a single 10-kΩ resistor.
• It is optional to disable PCI block through DEVDISR register after POR reset.
Option 2
If PCI arbiter is disabled during POR:
• All AD pins are in the input state. Therefore, all ADs pins need to be grouped together and tied to
OVDD through a single (or multiple) 10-kΩ resistor(s).
• All PCI control pins can be grouped together and tied to OVDD through a single 10-kΩ resistor.
• It is optional to disable PCI block through DEVDISR register after POR reset.
22.12 Guideline for LBIU Termination
If the LBIU parity pins are not used, the following is the termination recommendation:
• For LDP[0:3]—tie them to ground or the power supply rail via a 4.7-kΩ resistor.
• For LPBSE—tie it to the power supply rail via a 4.7-kΩ resistor (pull-up resistor).
