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.

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.

The peak value of the differential transmitter output signal or the differential
receiver input signal is defined as differential peak voltage, V
Since the differential output signal of the transmitter and the differential input
signal of the receiver each range from A – B to –(A – B) volts, the peak-to-peak
value of the differential transmitter output signal or the differential receiver input
