Option 2: Use the Respective Channel Transmitter Core Clocks
■
■
Enable this option if you want the individual transmitter channel’s tx_clkout
signal to provide the read clock to its respective Receive Phase Compensation
FIFO.
This option is typically enabled when all the transceiver channels have rate
matching enabled with different data rates and are reconfigured to another Basic
or Protocol functional mode with rate matching enabled.
