The parallel recovered clock from the receiver PMA in each channel clocks the word
aligner and the write port of the rate match FIFO. The low-speed parallel clock from
the transmitter local clock divider block in each channel clocks the read port of the
rate match FIFO, the 8B/10B decoder, and the write port of the byte deserializer (if
enabled). The parallel transmitter PCS 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 tx_clkout port as the FPGA fabric-Transceiver interface clock.
You can use the tx_clkout signal to latch the receiver data and status signals in the
FPGA fabric.

Bonded Channel Configurations
The Stratix IV device supports ×4 channel bonding that allows bonding of four
channels within the same transceiver block. It also supports ×8 channel bonding that
allows bonding of eight channels across two transceiver blocks on the same side of the
device.
In bonded channel configurations, the low-speed parallel clock for all bonded
channels are generated by the same CMU0 clock divider or the ATX clock divider block,
resulting in lower channel-to-channel clock skew. The receiver phase compensation
FIFO in all bonded channels (except in Basic [PMA Direct] ×N mode) share common
pointers and control logic generated in the CCU, resulting in equal latency in the
receiver phase compensation FIFO of all bonded channels.
Bonding is not supported on the receive side for Basic ×4 and Basic ×8 functional
modes. If you use rate matcher, the clocking scheme for Basic ×4 and Basic ×8
functional modes, the clocking is similar to PCIe ×4 mode, as shown in
page 2–46
