High-Speed Serial Interface (HSSI) DC Electrical Characteristics
The MSC8252 features an HSSI that includes two 4-channel SerDes ports used for high-speed serial interface applications (PCI
Express, Serial RapidIO interfaces, and SGMII). This section and its subsections describe the common portion of the SerDes
DC, including the DC requirements for the SerDes reference clocks and the SerDes data lane transmitter (Tx) and receiver (Rx)
reference circuits. The data lane circuit specifications are specific for each supported interface, and they have individual
subsections by protocol. The selection of individual data channel functionality is done via the Reset Configuration Word High
Register (RCWHR) SerDes Protocol selection fields (S1P and S2P). Specific AC electrical characteristics are defined in
2.5.2.1
Signal Term Definitions
The SerDes interface uses differential signaling to transfer data across the serial link. This section defines terms used in the
description and specification of differential signals. Figure 4 shows how the signals are defined. For illustration purposes only,
one SerDes lane is used in the description. Figure 4 shows the waveform for either a transmitter output (SR[1–2]_TX and
SR[1–2]_TX) or a receiver input (SR[1–2]_RX and SR[1–2]_RX). Each signal swings between A volts and B volts where
A>B.
