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
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.

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.
