Bonded Channel Configuration
In ×4 and ×8 bonded channel configurations, all channels within the transceiver block
are identical. The Quartus II software automatically drives the write port of the
transmitter phase compensation FIFO in all channels with the coreclkout signal. Use
the coreclkout signal to clock the transmitter data and control logic for all four
channels in the FPGA fabric.
