The parallel recovered clock from the receiver PMA in each channel clocks the word
aligner and write side of the rate match FIFO in that channel. The low-speed parallel
clock from the CMU0 clock divider of the master transceiver block 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 eight 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 in all eight channels. 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 eight bonded channels.
Both the receiver phase compensation FIFO pointers and the control circuitry from
Channel 0 in the master transceiver block are shared by the receiver phase
compensation FIFOs across all eight channels in PCIe ×8 mode.
Table 2–8
The FPGA fabric-transceiver interface clocks consist of clock signals from the FPGA
fabric to the transceiver blocks and clock signals from the transceiver blocks to the
FPGA fabric.
The FPGA fabric-transceiver interface clocks are divided into the following three
categories:
■

■
The CMU PLLs and receiver CDRs in each transceiver block derive the input
reference from one of the following sources:
