Asserted high—the CMU PLL is powered
down.
De-asserted low—the CMU PLL is active and
locks to the input reference clock.
Generated by the CMU0 clock divider in the
transceiver block in ×4 bonded channel
configurations.
Generated by the CMU0 clock divider in the
master transceiver block in ×8 bonded channel
configurations.
Not available in non-bonded channel
configurations.
Use to clock the write port of the transmitter
phase compensation FIFOs in all bonded
channels and to clock parallel data tx_datain
from the FPGA fabric into the transmitter
phase compensation FIFO of all bonded
channels.
Use to clock the read port of the receiver
phase compensation FIFOs in all bonded
channels with rate match FIFO enabled and to
clock parallel data rx_dataout from the
receiver phase compensation FIFOs of all
bonded channels (with rate match FIFO
enabled) into the FPGA fabric.
Also used for offset cancellation in all modes
except PCIe mode.
If configured in Transmitter only mode—the
frequency range is 2.5 MHz to 50 MHz.
If configured in Receiver only or Receiver
and Transceiver mode—the frequency
range of this clock is 37.5 MHz to 50 MHz.
