The CDR in each of the eight receiver channels recovers the serial clock from the
received data on that channel. The serial recovered clock frequency is half the
configured data rate. 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 from the receiver PMA in each channel is forwarded to the receiver PCS in that
channel.
