5.1.2.3. Deserializer

The deserializer block clocks in serial input data from the receiver buffer using the high-speed serial recovered clock and deserializes the data using the low-speed parallel recovered clock. The deserializer forwards the deserialized data to the receiver PCS or FPGA fabric.

The deserializer supports the following deserialization factors: 8, 10, 16, 20, 32, 40, and 64. The deserializer can be powered down when the CDR acts as a CMU.
