Functional Mode
The parallel recovered clock from the receiver PMA in each channel clocks the word
aligner in that channel. The parallel recovered clock from Channel 0 clocks the
deskew FIFO and the write port of the rate match FIFO in all four bonded channels.
The low-speed parallel clock from the CMU0 clock divider block in CMU0_Channel clocks
the read port of the rate match FIFO, the 8B/10B decoder, and the write port of the
byte deserializer (if enabled) in all four bonded channels. The low-speed parallel clock
or its divide-by-two version (if byte deserializer is enabled) clocks the write port of
the receiver phase compensation FIFO. It is also driven on the coreclkout port as the
FPGA fabric-Transceiver interface clock. You can use the coreclkout signal to latch
the receiver data and status signals in the FPGA fabric for all four bonded channels.
