Table 2–7. Receiver Datapath Clock Frequencies in ×4 Bonded Functional Modes Without Deskew FIFO for Arria II

Table
2–7:

In ×4 bonded channel configurations without deskew FIFO, the CDR in each receiver
channel recovers the serial clock from the received data. The serial recovered clock
frequency is half the configured data rate due to the half-rate CDR architecture. The
serial recovered clock is divided within each channel’s receiver PMA to generate the
parallel recovered clock. The deserializer uses the serial recovered clock in the
receiver PMA. The parallel recovered clock and deserialized data is forwarded to the
receiver PCS in each channel.
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 block in the 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). The low-speed parallel clock or its divide-by-two version (if byte
deserializer is enabled) clocks 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.
In ×4 bonded channel configurations, the receiver phase compensation FIFOs in all
four bonded channels share common read and write pointers and enable signals
generated in the CMU0 channel of the transceiver block.

without deskew FIFO.
×8 Bonded Channel Configuration
PCIe ×8 and Basic ×8 functional mode supports ×8 receiver channel bonding
configurations. The eight bonded channels are located in two transceiver blocks,
referred to as the master transceiver block and slave transceiver block, with four
channels each.
