Cyclone IV Device Handbook, Volume 2
In configuration with rate match FIFO, the transmitter datapath clocking is identical
to Transmitter Only operation as shown in
channel, the CDR unit recovers the clock from serial received data and generates the
high- and low-speed recovered clock for each bonded channel. The high-speed
recovered clock feeds the channel's deserializer, and low-speed recovered clock is
forwarded to receiver PCS. The individual low-speed recovered clock feeds to the
following blocks in the receiver PCS:
■
■
The common bonded low-speed clock that is used in all bonded transmitter PCS
datapaths feeds the following blocks in each bonded receiver PCS:
■
■
■
■
■
When the byte deserializer is enabled, the common bonded low-speed clock
frequency is halved before feeding to the write clock of RX phase compensation FIFO.
The common bonded low-speed clock is available in FPGA fabric as coreclkout
port, which can be used in FPGA fabric to send transmitter data and control signals,
and capture receiver data and status signals from the bonded channels.
