Document Table of Contents Byte Serializer

The byte serializer divides the input datapath by two to run the transceiver channel at higher data rates while keeping the FPGA fabric interface frequency within the maximum limit.

The byte serializer supports operation in single- and double-width modes. The datapath clock rate at the output of the byte serializer is twice the FPGA fabric–transmitter interface clock frequency. The byte serializer forwards the least significant word first followed by the most significant word.

Note: You must use the byte serializer in configurations that exceed the maximum frequency limit of the FPGA fabric–transceiver interface.
