16 High-Speed Serial Interfaces (HSSI)
The MPC8533E features two serializer/deserializer (SerDes) interfaces to be used for high-speed serial
interconnect applications.Both SerDes1 and SerDes2 can be used for PCI Express data transfers
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.

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.

receiver input (SDn_RX and SDn_RX). Each signal swings between A Volts and B Volts where A > B.
