1.2.1
MPC8568E Architecture Overview
e500 Core and Memory Unit
The MPC8568E contains a high-performance, 32-bit, Book E–enhanced e500v2 Power Architecture core.
In addition to 36-bit physical addressing, this version of the e500 core includes the following:
• Double-precision floating-point APU—Provides an instruction set for double-precision (64-bit)
floating-point instructions that use the 64-bit GPRs
• Embedded vector and scalar single-precision floating-point APUs—Provide an instruction set for
single-precision (32-bit) floating-point instructions
The MPC8568E also contains 512 Kbytes of L2 cache/SRAM, as follows:
• Eight-way set-associative cache organization with 32-byte cache lines
• Flexible configuration (can be configured as part cache, part SRAM)
• External masters can force data to be allocated into the cache through programmed memory ranges
or special transaction types (stashing).
• SRAM features include the following:
— I/O devices access SRAM regions by marking transactions as snoopable (global).
— Regions can reside at any aligned location in the memory map.

MPC8568E Overview
— Byte-accessible ECC uses read-modify-write transaction accesses for smaller-than-cache-line
accesses.
1.2.2
e500 Coherency Module (ECM) and Address Map
The e500 coherency module (ECM) provides a mechanism for I/O-initiated transactions to snoop the bus
between the e500 core and the integrated L2 cache in order to maintain coherency across local cacheable
memory. It also provides a flexible switch-type structure for core- and I/O-initiated transactions to be
routed or dispatched to target modules on the device.
The MPC8568E supports a flexible 36-bit physical address map. Conceptually, the address map consists of
local space and external address space. The local address map is supported by eight local access windows
that define mapping within the local 36-bit (64-Gbyte) address space.
The MPC8568E can be made part of a larger system address space through the mapping of translation
windows. This functionality is included in the address translation and mapping units (ATMUs). Both
inbound and outbound translation windows are provided. The ATMUs allows the MPC8568E to be part of
larger address maps such as the PCI or PCI Express 64-bit address environment and the RapidIO
environment.

incorporate a media access control (MAC) sublayer that supports 10- and 100-Mbps and 1-Gbps
Ethernet/802.3 networks with MII, RMII, GMII, RGMII, TBI, and RTBI physical interfaces. The eTSECs
include 2-Kbyte receive and 10-Kbyte transmit FIFOs and DMA functions.
The MPC8568E eTSECs support programmable CRC generation and checking, RMON statistics, and
jumbo frames of up to 9.6 Kbytes. Frame headers and buffer descriptors can be forced into the L2 cache
to speed classification or other frame processing. They are IEEE Std 802.3™, IEEE 802.3u, IEEE 802.3x,
IEEE 802.3z, IEEE 802.3ac, IEEE 802.3ab-compatible.
The buffer descriptors are based on the MPC8260 and MPC860T 10/100 Ethernet programming models.

DDR SDRAM Controller
The MPC8568E supports DDR SDRAM and DDR2 SDRAM. The memory interface controls main
memory accesses and provides for a maximum of 16 Gbytes of main memory.
The MPC8568E supports a variety of SDRAM configurations. SDRAM banks can be built using DIMMs
or directly-attached memory devices. Sixteen multiplexed address signals provide for device densities of
64 Mbits, 128 Mbits, 256 Mbits, 512 Mbits, 1 Gbits, 2 Gbits and 4 Gbits. Four chip select signals support
MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1

Freescale Semiconductor
MPC8568E Overview
up to four banks of memory. The MPC8568E supports bank sizes from 64 Mbytes to 4 Gbytes. Nine
column address strobes (MDM[0:8]) are used to provide byte selection for memory bank writes.
The MPC8568E can be configured to retain the currently active SDRAM page for pipelined burst accesses.
Page mode support of up to 16 simultaneously open pages (32 for DDR2) can dramatically reduce access
latencies for page hits. Depending on the memory system design and timing parameters, using page mode
can save 3 to 4 clock cycles from subsequent burst accesses that hit in an active page.
Using ECC, the MPC8568E detects and corrects all single-bit errors and detects all double-bit errors and
all errors within a nibble.
The MPC8568E can invoke a level of system power management by asserting the MCKE SDRAM signal
on-the-fly to put the memory into a low-power sleep mode.
1.2.7
Table Lookup Unit (TLU)
The table lookup unit (TLU) provides access to application-defined routing topology and control tables in
external memory. It accesses an external memory array attached to the local bus controller (LBC).
Communication between the CPU and the TLU occurs via messages passed through the TLU’s
memory-mapped configuration and status registers.
The TLU provides resources for efficient generation of table entry addresses in memory, hash generation
of addresses, and binary table searching algorithms for both exact-match and longest-prefix-match
strategies.It supports the following TLU complex table types:
• Hash-Trie-Key table for hash-based exact-match algorithms
• Chained-Hash table for partially indexed and hashed exact-match algorithms
• Longest-prefix-match algorithm
• Flat-Data table for retrieving search results and simple indexed algorithms
1.2.8

include:
• Compatible with the PCI Local Bus Specification, Revision 2.2, supporting 32- and 64-bit
addressing
• Can function as host or agent bridge interface
• As a master, supports read and write operations to PCI memory space, PCI I/O space, and PCI
configuration space
• Can generate PCI special-cycle and interrupt-acknowledge commands. As a target, it supports read
and write operations to system memory as well as configuration accesses.
• Supports PCI-to-memory and memory-to-PCI streaming, memory prefetching of PCI read
accesses, and posting of processor-to-PCI and PCI-to-memory writes
• PCI 3.3-V compatible with selectable hardware-enforced coherency

MPC8568E Overview
1.2.9
High Speed I/O Interfaces
The MPC8568E supports two high-speed I/O interface standards: serial RapidIO and PCI Express. It can
be configured as x1/x4 SRIO and 1x/2x/4x PCI Express simultaneously with the following limitation:
• Both SRIO and PCI-Express are limited to use the same clock and are limited to 2.5G.
• Spread spectrum clocking can not be used because SRIO doesn't support this (PCI-Express does
support it).
If x8 PCI Express is needed, then SRIO is not available due to the pin multiplex limitation.
1.2.10 Serial RapidIO
The serial RapidIO interface is based on the RapidIO Interconnect Specification, Revision 1.2. RapidIO is
a high-performance, point-to-point, low-pin-count, packet-switched system-level interconnect that can be
used in a variety of applications as an open standard. The RapidIO architecture has a rich variety of
features including high data bandwidth, low-latency capability, and support for high-performance I/O
devices, as well as support for message-passing and software-managed programming models. Key features
of the serial RapidIO interface unit include:
• Support for RapidIO Interconnect Specification, Revision 1.2 (all transaction flows and priorities)
• Both 1x and 4x LP-serial link interfaces, with transmission rates of 1.25, 2.5, and 3.125 Gbaud
(data rates of 1.0, 2.0, and 2.5 Gbps) per lane
• Auto detection of 1x or 4x mode operation during port initialization
• 34-bit addressing and up to 256-byte data payload
• Receiver-controlled flow control
• Support for RapidIO error injection
The RapidIO messaging unit supports two inbox/outbox mailboxes (queues) for data and one doorbell
message structure. Both chaining and direct modes are provided for the outbox, and messages can hold up
to 16 packets of 256 bytes, or a total of 4 Kbytes.
1.2.11 PCI Express Interface
The MPC8568E supports a PCI Express interface compatible with the PCI Express Base Specification
Revision 1.0a. It is configurable at boot time to act as either root complex or endpoint.The physical layer
of the PCI Express interface operates at a 2.5-Gbaud data rate per lane.
Other features of the PCI Express interface include:
• x8, x4, x2, and x1 link widths supported
• Selectable operation as root complex or endpoint
• Both 32- and 64-bit addressing and 256-byte maximum payload size
• Full 64-bit decode with 32-bit wide windows

Freescale Semiconductor
MPC8568E Overview
1.2.12
Programmable Interrupt Controller (PIC)
The MPC8568E PIC implements the logic and programming structures of the OpenPIC architecture,
providing for external interrupts (with fully nested interrupt delivery), message interrupts, internal-logic
driven interrupts, and global high-resolution timers. Up to 16 programmable interrupt priority levels are
supported.
The PIC can be bypassed to allow use of an external interrupt controller.
1.2.13
DMA Controller, I2C, DUART, and Local Bus Controller
The MPC8568E provides an integrated four-channel DMA controller, which can transfer data between any
of its I/O or memory ports or between two devices or locations on the same port. The DMA controller also:
• Allows chaining (both extended and direct) through local memory-mapped chain descriptors.
• Scattering, gathering, and misaligned transfers are supported. In addition, stride transfers and
complex transaction chaining are supported.
• Local attributes such as snoop and L2 write stashing can be specified.
There are two I2C controllers. These synchronous, multimaster buses can be connected to additional
devices for expansion and system development.
The DUART supports full-duplex operation and is compatible with the PC16450 and PC16550
programming models. 16-byte FIFOs are supported for both the transmitter and the receiver.
The MPC8568E local bus controller (LBC) port allows connections with a wide variety of external
memories, DSPs, and ASICs. Three separate state machines share the same external pins and can be
programmed separately to access different types of devices. The general-purpose chip select machine
(GPCM) controls accesses to asynchronous devices using a simple handshake protocol. The user
programmable machine (UPM) can be programmed to interface to synchronous devices or custom ASIC
interfaces. The SDRAM controller provides access to standard SDRAM. Each chip select can be configured
so that the associated chip interface can be controlled by the GPCM, UPM, or SDRAM controller. All may
exist in the same system. The local bus controller supports the following features:
• Multiplexed 32-bit address and data bus operating at up to 133 MHz
• Eight chip selects support eight external slaves
• Up to eight-beat burst transfers
• 32-, 16-, and 8-bit port sizes controlled by on-chip memory controller
• Three protocol engines available on a per-chip-select basis
• Parity support
• Default boot ROM chip select with configurable bus width (8, 16, or 32 bits)
• Supports zero-bus-turnaround (ZBT) RAM
1.2.14
Power Management
In addition to low-voltage operation and dynamic power management, which automatically minimizes
power consumption of blocks when they are idle, four power consumption modes are supported: full on,
doze, nap, and sleep.

Electrical Characteristics
The core voltage must always be provided at nominal 1.1V. (See Table 3 for actual recommended core
voltage). 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 3. 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.

2.2
Power Sequencing
The MPC8568E requires its power rails to be applied in specific sequence in order to ensure proper device
operation. These requirements are as follows for power up:
1. VDD, AVDD_n, BVDD, SCOREVDD, LVDD, TVDD, XVDD, OVDD
2. GVDD
All supplies must be at their stable values within 50 ms.

Power Characteristics
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.
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.

The power dissipation of VDD for various core complex bus (CCB) versus the core and QE frequency for
MPC8568E is shown in Table 5. Note that this is based on the design estimate only. More accurate power

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 23.2, “CCB/SYSCLK PLL Ratio and Section 23.3,
“e500 Core PLL Ratio,” for ratio settings.
2. Rise and fall times for SYSCLK are measured at 0.4 V 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.

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 Time Base unit of the e500. There is no need for 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.

generated by the eTSEC GTX_CLK. See Section 8.2.6, “RGMII and RTBI AC Timing Specifications,” for duty cycle
for 10Base-T and 100Base-T reference clock.
3. Rise and fall times for EC_GTX_CLK125 are measured from 0.5 and 2.0 V for L/TVDD = 2.5 V, and from 0.6 and 2.7

FIFO Clock Speed Restrictions
Note the following FIFO maximum speed restrictions based on the 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 higher
than 127 MHz.
For FIFO encoded mode:
FIFO TX/RX clock frequency <= platform clock frequency / 3.2
For example, if the platform frequency is 533 MHz, the FIFO TX/RX clock frequency should be no higher
than 167 MHz

determined by the following equation: tDISKEW =+/-(T/4 – abs(tCISKEW)) where T is the clock period and abs(tCISKEW)
is the absolute value of tCISKEW.
3. Maximum DDR1 frequency is 400 MHz.

Note:
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 DQSS override bits in the TIMING_CFG_2 register. This will typically be set to the same delay as the clock
adjust in the CLK_CNTL register. The timing parameters listed in the table assume that these 2 parameters have been set
to the same adjustment value. See the MPC8568E Integrated Communications Processor Reference Manual for a
description and understanding of the timing modifications enabled by use of these bits.
5. Determined by maximum possible skew between a data strobe (MDQS) and any corresponding bit of data (MDQ), ECC
(MECC), or data mask (MDM). The data strobe should be centered inside of the data eye at the pins of the microprocessor.
6. All outputs are referenced to the rising edge of MCK[n] at the pins of the microprocessor. Note that tDDKHMP follows the
symbol conventions described in note 1.
7. Maximum DDR1 frequency is 400 MHz

Ethernet Interface and MII Management
This section provides the AC and DC electrical characteristics for eTSEC, MII management and Ethernet
interface inside QUICC Engine. Note that eTSEC and QE Ethernet have the same DC/AC characteristics.
8.1
GMII/MII/TBI/RGMII/RTBI/RMII Electrical Characteristics
The electrical characteristics specified here apply to all gigabit media independent interface (GMII), media
independent interface (MII), ten-bit interface (TBI), reduced gigabit media independent interface
(RGMII), reduced ten-bit interface (RTBI), and reduced media independent interface (RMII) signals
except management data input/output (MDIO) and management data clock (MDC). The RGMII and RTBI
interfaces are defined for 2.5 V, while the GMII and TBI interfaces can be operated at 3.3 or 2.5 V. Whether
the GMII, MII, or TBI interface is operated at 3.3 or 2.5 V, the timing is compatible with the IEEE 802.3
standard. The RGMII and RTBI interfaces follow the Reduced Gigabit Media-Independent Interface
(RGMII) Specification Version 1.3 (12/10/2000). The RMII interface follows the RMII Consortium RMII
MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1

Freescale Semiconductor
Ethernet Interface and MII Management
Specification Version 1.2 (3/20/1998). The electrical characteristics for MDIO and MDC are specified in
Section 8, “Ethernet Interface and MII Management.”
8.1.1
Ethernet Interface DC Electrical Characteristics
All GMII, MII, TBI, RGMII, RMII and RTBI drivers and receivers comply with the DC parametric
attributes specified in Table 23 and Table 24. The potential applied to the input of a GMII, MII, TBI,
RGMII, RMII or RTBI receiver may exceed the potential of the receiver’s power supply (that is, a GMII
driver powered from a 3.6-V supply driving VOH into a GMII receiver powered from a 2.5-V supply).
Tolerance for dissimilar GMII driver and receiver supply potentials is implicit in these specifications. The
RGMII and RTBI signals are based on a 2.5-V CMOS interface voltage as defined by JEDEC
EIA/JESD8-5.

8.2
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 performance 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.
MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1
28
Freescale Semiconductor
Ethernet Interface and MII Management
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
4.4, “Platform to FIFO restrictions.

Notes:
1. The symbols used for timing specifications herein 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).

TBI Single-Clock Mode AC Specifications
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 TSECn 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
on the TSEC_GTX_CLK125 pin in all TBI modes.
A summary of the single-clock TBI mode AC specifications for receive appears in Table 33.

Notes:
1. Note that, 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 will require clocks to be routed such that an additional trace delay of greater than
1.5 ns will be 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. EC_GTX_CLK125 is used to generate GTX_CLK for the eTSEC transmitter with 2% degradation. EC_GTX_CLK125
duty cycle can be loosen from 47/53% as long as the PHY device can tolerate the duty cycle generated by the eTSEC
GTX_CLK.

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 BV DD/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

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 30).
Time-of-flight delays must be added for trace lengths, vias, and connectors in the system.
2. The symbols used for timing specifications herein 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.

Note:
1.The symbols used for timing specifications herein 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, 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.
2. As a transmitter, the MPC8568 provides a delay 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 to avoid unintended generation of START or STOP condition.
When the MPC8568 acts as the I2C bus master while transmitting, the MPC8568 drives both SCL and SDA. As long as the
load on SCL and SDA are balanced, the MPC8568 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 the MPC8568 as transmitter, application note AN2919 referred to in note 4 below is recommended.
3. The maximum tI2DXKL has only to be met if the device does not stretch the LOW period (tI2CL) of the SCL signal.
4.The requirements for I2C frequency calculation must be followed. Refer to Freescale application note AN2919, Determining
the I2C Frequency Divider Ratio for SCL

Notes:
1. Note that the symbols used for timing specifications herein 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, tPCIVKH symbolizes PCI 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 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 PCI_CLK to 0.4 × OV DD 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 23, “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.

13 High-Speed Serial Interfaces (HSSI)
The MPC8568E features one Serializer/Deserializer (SerDes) interfaces to be used for high-speed serial
interconnect applications. It 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.
13.1
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 39 shows how the signals are defined. For illustration purpose, only one SerDes lane is used for
description. The figure shows 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 illustration, the following definitions
assume that the SerDes transmitter and receiver operate in a fully symmetrical differential signaling
environment.
1. 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.
2. 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.
3. Differential Input Voltage, VID (or Differential Input Swing):
MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1
Freescale Semiconductor
61
High-Speed Serial Interfaces (HSSI)
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.
4. 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.
5. Differential Peak-to-Peak, VDIFFp-p
Since 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-peak voltage
can also be calculated as VTX-DIFFp-p = 2*|VOD|.
6. 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 as the DC offset in
some occasion.

Figure 39. Differential Voltage Definitions for 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 V and 2.0 V. Using these values, the peak-to-peak voltage swing of each signal (TD
or TD) is 500 mV p-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
MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1
62
Freescale Semiconductor
High-Speed Serial Interfaces (HSSI)
between 500 mV 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 mV p-p.
13.2
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.
The following sections describe the SerDes reference clock requirements and some application
information.
13.2.1
SerDes Reference Clock Receiver Characteristics
Figure 40 shows a receiver reference diagram of the SerDes reference clocks.
• The supply voltage requirements for SCOREVDD and XVDD are specified in Table 2 and Table 3.
• 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 40. Each differential clock input (SD_REF_CLK or SD_REF_CLK) has a 50-Ω
termination to SCOREGND 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 8mA. 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 0.4V
(0.4V/50 = 8mA) while the minimum common mode input level is 0.1V above SCOREGND.
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 0mA to 16mA (0-0.8V), such that each phase of the
differential input has a single-ended swing from 0V to 800mV with the common mode voltage
at 400mV.
— If the device driving the SD_REF_CLK and SD_REF_CLK inputs cannot drive 50 ohms to
SCOREGND 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.

DC Level Requirement for SerDes Reference Clocks
The DC level requirement for the MPC8568E 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 400mV and 1600mV differential
peak-peak (or between 200mV and 800mV differential peak). In other words, each signal wire
of the differential pair must have a single-ended swing less than 800mV and greater than
200mV. This requirement is the same for both external DC-coupled or AC-coupled connection.
— For external DC-coupled connection, as described in section 13.2.1, the maximum average
current requirements sets the requirement for average voltage (common mode voltage) to be
between 100 mV and 400 mV. Figure 41 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
SCOREGND. Each signal wire of the differential inputs is allowed to swing below and above
the command mode voltage (SCOREGND). Figure 42 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 400mV and 800mV peak-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 43 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 SCOREGND, 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 44 to Figure 47 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 MPC8568 SerDes reference clock receiver requirement
provided in this document.

Since LVDS clock driver’s common mode voltage is higher than the MPC8568 SerDes reference clock

LVDS output driver features 50-Ω termination resistor. It also assumes that the LVDS transmitter
establishes its own common mode level without relying on the receiver or other external component.

High-Speed Serial Interfaces (HSSI)
Figure 46 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
MPC8568 SerDes reference clock input’s DC requirement, AC-coupling has to be used. Figure 46
assumes that the LVPECL clock driver’s output impedance is 50Ω. R1 is used to DC-bias the LVPECL
outputs prior to AC-coupling. Its value could be ranged from 140Ω to 240Ω depending on 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 MPC8568 SerDes
reference clock’s differential input amplitude requirement (between 200mV and 800mV differential peak).
For example, if the LVPECL output’s differential peak is 900mV and the desired SerDes reference clock
input amplitude is selected as 600mV, the attenuation factor is 0.67, which requires R2 = 25Ω. Consult
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 14.2, “AC Requirements for PCI Express SerDes Clocks”
• Section 15.2, “AC Requirements for Serial RapidIO SD_REF_CLK and SD_REF_CLK”
13.2.4.1
Spread Spectrum Clock
SD_REF_CLK/SD_REF_CLK were 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 collected over any 250 consecutive TX UIs. The TTX-EYE-MEDIAN-to-MAX-JITTER median is less than half of the total
TX 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.
4. The Transmitter input impedance shall result in a differential return loss greater than or equal to 12 dB and a common mode
return loss greater than or equal to 6 dB 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 is 50 Ω to ground for both the D+ and
D- line (that is, as measured by a Vector Network Analyzer with 50 ohm probes—see Figure 51). Note that the series capacitors
CTX is optional for the return loss measurement.

Transmitter Compliance Eye Diagrams
The TX eye diagram in Figure 49 is specified using the passive compliance/test measurement load (see
Figure 51) 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 will 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 will always be relative to the transition bit.
The eye diagram must be valid for any 250 consecutive UIs.

A recovered TX UI is calculated over 3500 consecutive unit intervals of sample data. The eye diagram is

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 51 should be used
as the RX device when taking measurements (also refer to the Receiver compliance eye diagram shown in Figure 50). 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 ohms to ground for both the D+ and D- line (that is, as measured
by a Vector Network Analyzer with 50 ohm probes—see Figure 51). 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 un-configured 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 will 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.
14.5
Receiver Compliance Eye Diagrams
The RX eye diagram in Figure 50 is specified using the passive compliance/test measurement load (see
Figure 51) 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 51) will be 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 50) 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.

15 Serial RapidIO
This section describes the DC and AC electrical specifications for the RapidIO interface of the
MPC8568E, for the LP-Serial physical layer. The electrical specifications cover both single and
multiple-lane links. Two transmitters (short run 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 will accept signals
from both the short run 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 will be 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 52 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:
7. 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
8. The differential output signal of the transmitter, VOD, is defined as VTD–VTD
9. The differential input signal of the receiver, VID, is defined as VRD-VRD
10. The differential output signal of the transmitter and the differential input signal of the receiver
each range from A – B to –(A – B) Volts
11. The peak value of the differential transmitter output signal and the differential receiver input
signal is A – B Volts
12. The peak-to-peak value of the differential transmitter output signal and the differential receiver
input signal is 2 * (A – B) Volts

Serial RapidIO
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 V and 2.0 V. Using these values, the peak-to-peak voltage swing of the signals TD
and TD is 500 mV p-p. The differential output signal ranges between 500 mV and –500 mV. The peak
differential voltage is 500 mV. The peak-to-peak differential voltage is 1000 mV p-p.
15.4
Equalization
With the use of high speed serial links, the interconnect media will cause 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.
15.5
Explanatory Note on Transmitter and Receiver Specifications
AC electrical specifications are given for transmitter and receiver. Long run 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.
15.6
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 Ohm 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.

Measurement and Test Requirements
Since the LP-Serial electrical specification are guided by the XAUI electrical interface specified in Clause
47 of IEEE 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 802.3ae-2002 is specified as
the test pattern for use in eye pattern and jitter measurements. Annex 48B of IEEE 802.3ae-2002 is
recommended as a reference for additional information on jitter test methods.
15.9.1
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
MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1
Freescale Semiconductor
87
Serial RapidIO
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 Volts
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 Ohms resistive +/– 5% differential to 2.5 GHz.
15.9.2
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 Volts 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.
15.9.3
Transmit Jitter
Transmit jitter is measured at the driver output when terminated into a load of 100 Ohms resistive +/– 5%
differential to 2.5 GHz.
15.9.4
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 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 and
. 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 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.
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 23.2, “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 23.3, “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 will therefore be described as an I/O for boundary scan.
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 V DD/GND planes internally and may be used by the core power supply to improve tracking
and regulation.
14.Internal thermally sensitive resistor. These two pins are not ESD protected.
17.. The value of PA[0:4] during reset set the QE clock to SYSCLK PLL ratio. These pins require 4.7-kΩ pull-up or pull-down
resistors. See Section 23.4, “QE/SYSCLK PLL Ratio.”
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.
25.These are test signals for factory use only and must be pulled up (100 - 1 K) to OVDD for normal machine operation.
26. Independent supplies derived from board VDD.
27. Recommend a pull-up resistor (~1 K.) be placed on this pin to OVDD.
29. The following pins must NOT be pulled down during power-on reset: HRESET_REQ, TRIG_OUT/READY/QUIESCE,
MSRCID[2:4], ASLEEP, PA[5]

Notes
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.
33. PF[21:22] are multiplexed as cfg_dram_type[0:1]. THEY MUST BE VALID AT POWER-UP, EVEN BEFORE HRESET
ASSERTION.
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 will drive 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.MDIC[0] is grounded through an 18.2-Ω precision 1% resistor and MDIC[1] is connected to GVDD through an 18.2-Ω precision
1% resistor. These pins are used for automatic calibration of the DDR IOs.
39. If PCI is configured as PCI asynchronous mode, a valid clock must be provided on pin PCI_CLK . Otherwise the processor
will not boot up.
41.These pins should be tied to SCOREGND through a 300 ohm resistor if the high speed interface is used.
43. It is highly recommended that unused SD_RX/SD_RX lanes should be powered down with lane_x_pd. Otherwise the
receivers will burn extra power and the internal circuitry may develop long term reliability problems.
44. See Section 25.9, “Guidelines for High-Speed Interface Termination.”
46. Must be high during HRESET. It is recommended to leave the pin open during HRESET since it has internal pullup resistor.
47. Must be pulled down with 4.7-kΩ resistor.
48. This pin must be left no connect.
49. A pull-up on LGPL4 is required for systems that boot from local bus (GPCM)-controlled NOR Flash.

Notes
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.
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 23.2, “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 23.3, “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 will therefore be described as an I/O for boundary scan.
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. These two pins are not ESD protected.
17.. The value of PA[0:4] during reset set the QE clock to SYSCLK PLL ratio. These pins require 4.7-kΩ pull-up or pull-down
resistors. See Section 23.4, “QE/SYSCLK PLL Ratio.”
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.
25.These are test signals for factory use only and must be pulled up (100 - 1 K) to OVDD for normal machine operation.
26. Independent supplies derived from board VDD.
27. Recommend a pull-up resistor (~1 K.) be placed on this pin to OVDD.
29. The following pins must NOT be pulled down during power-on reset: HRESET_REQ, TRIG_OUT/READY/QUIESCE,
MSRCID[2:4], ASLEEP, PA[5].

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.
33. PF[21:22] are multiplexed as cfg_dram_type[0:1]. THEY MUST BE VALID AT POWER-UP, EVEN BEFORE HRESET
ASSERTION.
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 will drive 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.MDIC[0] is grounded through an 18.2-Ω precision 1% resistor and MDIC[1] is connected to GVDD through an 18.2-Ω precision
1% resistor. These pins are used for automatic calibration of the DDR IOs.
39. If PCI is configured as PCI asynchronous mode, a valid clock must be provided on pin PCI_CLK . Otherwise the processor
will not boot up.
41.These pins should be tied to SCOREGND through a 300 ohm resistor if the high speed interface is used.
43. It is highly recommended that unused SD_RX/SD_RX lanes should be powered down with lane_x_pd. Otherwise the receivers
will burn extra power and the internal circuitry may develop long term reliability problems.
44. See Section 25.9, “Guidelines for High-Speed Interface Termination.”
46. Must be high during HRESET. It is recommended to leave the pin open during HRESET since it has internal pullup resistor.
47. Must be pulled down with 4.7-kΩ resistor.
48. This pin must be left no connect.
49. A pull-up on LGPL4 is required for systems that boot from local bus (GPCM)-controlled NOR Flash.
23 Clocking
This section describes the PLL configuration of the MPC8568E. Note that the platform clock is identical
to the core complex bus (CCB) clock.

23.2
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 83:
• 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.

Minimum Platform Frequency Requirements for PCI Express, SRIO,
PCI interfaces Operation
For proper PCI Express operation, the CCB clock frequency must be greater than:
527 MHz × ( PCI Express link width )
---------------------------------------------------------------------------------------------8
Note that the “PCI Express link width” in the above equation refers to the negotiated link width as the
result of PCI Express link training, which may or may not be the same as the link width POR selection.
For proper Serial RapidIO operation, the CCB clock frequency must be greater than:
2 × ( 0.80 ) × ( serial RapidIO interface frequency ) × ( serial RapidIO link width )
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------64
For proper PCI operation in synchronous mode, the minimum CCB:SYSCLK ratio is 6:1.

board with the spring force centered over the die. This spring force should not exceed 10 pounds force.

MPC8568E to function in various environments.
24.2.1
Recommended Thermal Model
For system thermal modeling, the MPC8568E thermal model without a lid is shown in Figure 70. The
substrate is modeled as a block 33x33x1.18 mm with an in-plane conductivity of 24 W/mK and a
through-plane conductivity of 0.92 W/mK. The solder balls and air are modeled as a single block
33x33x0.58 mm with an in-plane conductivity of 0.034 W/mK and a through plane conductivity of 12.2
W/mK. The die is modeled as 8.2x12.1 mm with a thickness of 0.75 mm. The bump/underfill layer is
modeled as a collapsed thermal resistance between the die and substrate assuming a conductivity of 5.3
W/m•K in the thickness dimension of 0.07 mm. The die is centered on the substrate. The thermal model
uses approximate dimensions to reduce grid. See the case outline for actual dimensions.

The heat sink removes most of the heat from the device. Heat generated on the active side of the chip is
conducted through the silicon, then through the heat sink attach material (or thermal interface material),
and finally to the heat sink. The junction-to-case thermal resistance is low enough that the heat sink attach
material and heat sink thermal resistance are the dominant terms.
24.2.3
Thermal Interface Materials
A thermal interface material is required at the package-to-heat sink interface to minimize the thermal
contact resistance. For those applications where the heat sink is attached by spring clip mechanism,
Figure 72 shows the thermal performance of three thin-sheet thermal-interface materials (silicone,
graphite/oil, floroether oil), a bare joint, and a joint with thermal grease as a function of contact pressure.
As shown, the performance of these thermal interface materials improves with increasing contact pressure.
The use of thermal grease significantly reduces the interface thermal resistance. The bare joint results in a
thermal resistance approximately six times greater than the thermal grease joint.
Heat sinks are attached to the package by means of a spring clip to holes in the printed-circuit board (see
Figure 69). Therefore, the synthetic grease offers the best thermal performance, especially at the low
interface pressure.

25 System Design Information
This section provides electrical and thermal design recommendations for successful application of the
MPC8568E.
25.1
System Clocking
This device includes six 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 23.2, “CCB/SYSCLK PLL Ratio.”
2. The e500 core PLL generates the core clock using the platform clock as the input. 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 23.3, “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.
6. QE PLL generates the QE clock from the externally supplied SYSCLK.
25.2
25.2.1
Power Supply Design and Sequencing
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, AVDD_CE respectively). The AVDD
level should always be equivalent to VDD, and preferably these voltages will be derived directly from VDD
through a low frequency filter scheme such as the following.
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 73, one to each of the
AVDD type 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.
MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1
130
Freescale Semiconductor
System Design Information
Each circuit should be placed as close as possible to the specific AVDD type pin being supplied to minimize
noise coupled from nearby circuits. It should be possible to route directly from the capacitors to the AVDD
type pin, which is on the periphery of 1023FC-PBGA the footprint, without the inductance of vias.
Figure 73 shows the PLL power supply filter circuits for all PLLs except SerDes PLL.

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 and AGND_SRDS ball to ensure it filters out as much noise as possible. The 0.003-µF
capacitor is closest to the ball, followed by the 2.2-µF capacitors, and finally the 1 ohm resistor to the board
supply plane. Use ceramic chip capacitors with the highest possible self-resonant frequency. All traces
should be kept short, wide and direct.

• The transmitter output signals on the SerDes interface are fed from the XVDD power plan.
• Power: XVDD consumes less than 300mW. SCOREVDD + AVDD_SRDS consumes less than
750mW.
25.3
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.
MPC8568E 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 V DD, TVDD,
BVDD, OVDD, GVDD, and LVDD pin of the device. These decoupling capacitors should receive their
power from separate VDD,TVDD, BVDD, OVDD, GVDD, and LVDD and GND power planes in the PCB,
utilizing short traces to minimize inductance. Capacitors may be placed directly under the device using a
standard escape pattern. Others may surround the part.
MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1
Freescale Semiconductor
131
System Design Information
These capacitors should have a value of 0.01 or 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).
25.4
SerDes Block Power Supply Decoupling Recommendations
The SerDes block requires a clean, tightly regulated source of power (SCOREVDD 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 x 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
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 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.
25.5
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, LVDD, TVDD,
BVDD, OVDD, GVDD and GND pins of the device.
25.6
Pull-Up and Pull-Down Resistor Requirements
The MPC8568E requires weak pull-up resistors (2–10 kΩ is recommended) on open drain type pins
including I2C pins and MPIC interrupt pins.
Correct operation of the JTAG interface requires configuration of a group of system control pins as
demonstrated in Figure 75. 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 will
give unpredictable results.
MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1
132
Freescale Semiconductor
System Design Information
Refer to the PCI 2.2 specification for all pull-ups required for PCI.
The following pins must NOT be pulled down during power-on reset: HRESET_REQ,
TRIG_OUT/READY/QUIESCE, MSRCID[2:4], ASLEEP, PA[5].
Three test pins also require pull-up resistors (100 Ω–1 KΩ). These pins are L1_TSTCLK, L2_TSTCLK,
and LSSD_MODE. These signals are for factory use only and must be pulled up to OVDD for normal
machine operation.
Refer to the PCI 2.2 specification for all pull-ups required for PCI.
25.7
Configuration Pin Muxing
The MPC8568E 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. 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 pull-up resistors 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
HRESET is negated, the pull-up resistor is also disabled, 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.
The platform PLL ratio and e500 PLL ratio configuration pins are not equipped with these default pull-up
devices.
25.8
JTAG Configuration Signals
Boundary scan testing is enabled through the JTAG interface signals. The TRST signal is optional in the
IEEE 1149.1 specification, but is provided on all processors that implement Power Architecture. The
device requires TRST to be asserted during reset conditions to ensure the JTAG boundary logic does not
interfere with normal chip operation. While it is possible to force the TAP controller to the reset state using
only the TCK and TMS signals, generally systems will assert TRST during power-on reset. Because the
JTAG interface is also used for accessing the common on-chip processor (COP) function, simply tying
TRST to HRESET is not practical.
The COP function of these processors allows 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
MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1
Freescale Semiconductor
133
System Design Information
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 75 allows the COP to independently assert HRESET or TRST, while
ensuring that the target can drive HRESET as well. If the JTAG interface and COP header will not be used,
TRST should be tied to HRESET so that it is asserted when the system reset signal (HRESET) is asserted.
The COP header shown in Figure 75 adds many benefits—breakpoints, watchpoints, register and memory
examination/modification, and other standard debugger features are possible through this interface—and
can be as inexpensive as an unpopulated footprint for a header to be added when needed.
The COP interface has a standard header for connection to the target system, based on the 0.025"
square-post, 0.100" centered header assembly (often called a Berg header).
There is no standardized way to number the COP header shown in Figure 75; consequently, many different
pin numbers have been observed from emulator vendors. Some are numbered top-to-bottom then
left-to-right, while others use left-to-right then top-to-bottom, while still others number the pins counter
clockwise from pin 1 (as with an IC). Regardless of the numbering, the signal placement recommended in
Figure 75 is common to all known emulators.

SerDes block power not supplied
If the high speed interface is not used at all, then SCOREVDD/XVDD/AVDD_SRDS can be tied to GND,
all receiver inputs should be tied to the GND as well. This includes:

• SD_RX[7:0]
• SD_REF_CLK
• SD_REF_CLK
• SD_RX_CLK
• SD_RX_FRM_CTL
25.9.2.2
SerDes Interface Partly used
If the high-speed SerDes interface is partly unused, any of the unused receiver pins should be terminated
as follows:
• SD_RX[7:0] = tied to SCOREGND
• SD_RX[7:0] = tied to SCOREGND
• SD_REF_CLK = tied to SCOREGND
• SD_REF_CLK = tied to SCOREGND
NOTE
Power down the unused lane through SERDESCR1[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.
During HRESET/POR, the high-speed interface must be in Serial RapidIO mode and/or PCI Express mode
according to the state of the PE[8:10]. Software must disable this mode through DEVDISR[SRIO] or
DEVDISR[PCIE] accordingly during software initialization.
