Common Clock Driver Selection Rules
The common clock driver driving the rx_coreclk ports of all channels must have a
0 PPM frequency difference with respect to the receiver phase compensation FIFO
write clocks of these channels. If there is any frequency difference between the FIFO
read clock (rx_coreclk) and the FIFO write clock, the FIFO overflows or under-runs,
resulting in corrupted data transfer between the FPGA fabric and the receiver.
