Bonded Channel Configuration
All bonded transceiver channel configurations have rate matcher in the receiver data
path. In ×4 and ×8 bonded channel configurations, the Quartus II software
automatically drives the read port of the receiver phase compensation FIFO in all
channels with the coreclkout signal (from the master transceiver block in the case of
×8 bonded mode). Use the coreclkout signal to latch the receiver data and status
signals from all channels in the FPGA fabric.
This configuration uses one FPGA global and/or regional clock resource per bonded
link for the coreclkout signal.
