Deserializer
The deserializer block latches the serial input data from the receiver input buffer with
the high-speed serial recovery clock, deserializes it using the low-speed parallel
recovery clock, and drives the deserialized data to the receiver PCS channel.
The deserializer supports 8-, 10-, 16-, and 20-bit deserialization factors.
shows the deserializer operation with a 10-bit deserialization factor.

data output of the deserializer block with a 10-bit deserialization factor. The serial
stream (10'b0101111100) is deserialized to a value 10'h17C. The serial data is assumed
to have received the LSB first.
