The transmitter side receives its clocks from the clock multiplier unit (CMU) PLLs.
The receiver side contains its dedicated CDR that provides the high-speed serial and
low-speed parallel clocks to its PMA and PCS blocks, respectively.

The design requires independent control on all channels, so
you must not share the transceiver-FPGA fabric interface
clock of one channel with another channel. Each of the
channels must use its own tx_clkout and rx_clkout
signals to clock the data between the transceiver channels and
the FPGA fabric.
Yes
