The MPC8536E features two Serializer/Deserializer (SerDes) interfaces to be used for high-speed serial interconnect
applications. The SerDes1 interface is dedicated for PCI Express data transfers. The SerDes2 can be used for SGMII or SATA.
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.
2.20.1
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.
Figure 57
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.
The transmitter output signals and the receiver input signals SDn_TX, SDn_TX, SDn_RX and SDn_RX each have a
