Limitations of Quartus II Software-Selected Receiver Phase Compensation FIFO Read Clock
In non-bonded channel configurations without a rate matcher, the Quartus II software
cannot determine if the incoming serial data in all channels has a 0 PPM frequency
difference. The Quartus II software uses the recovered clock rx_clkout signal from
each channel to clock the read port of its receiver phase compensation FIFO, resulting
in one clock resource (global, regional, or both) being used per channel for the
rx_clkout signal.
