15 High-Speed Serial Interfaces (HSSI)
The MPC8572E features two Serializer/Deserializer (SerDes) interfaces to be used for high-speed serial
interconnect applications. The SerDes1 interface can be used for PCI Express and/or Serial RapidIO data
transfers. The SerDes2 is dedicated for SGMII application.
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.
15.1
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 43 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 (SDn_TX and SDn_TX) or a
receiver input (SDn_RX and SDn_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 SDn_TX, SDn_TX, SDn_RX and
SDn_RX each have a peak-to-peak swing of A - B Volts. This is also referred as each signal wire’s
Single-Ended Swing.

Notes:
1. Input specifications are measured from the 50% level of the signal to the 50% level of the rising edge of SYSCLK. Timings
are measured at the pin.
2. GPIO inputs and outputs are asynchronous to any visible clock. GPIO outputs should be synchronized before use by any
external synchronous logic. GPIO inputs are required to be valid for at least tPIWID ns to ensure proper operation.
