Option 2: Use the Respective Channel Transmitter Core Clocks
■
■
Enable this option if you want the individual transmitter channel tx_clkout
signals to provide the write clock to their respective Transmit Phase Compensation
FIFOs.
This option is typically enabled when each transceiver channel is reconfigured to a
different functional mode using channel reconfiguration.
