2.2.3.1. Receiver Non-Bonded Channel Configurations

The receiver clocking in non-bonded mode varies, depending on whether the rate match FIFO is enabled. When the rate match FIFO is not enabled, the receiver PCS in every channel uses the parallel recovered clock. When the rate match FIFO is enabled, the receiver PCS in every channel uses both the parallel recovered clock and parallel clock from the clock divider.

For Arria V GZ devices, in non-bonded configurations the receiver 10G PCS uses only the parallel clock (recovered) for all its blocks.
