Document Table of Contents Byte Deserializer Deserialize x4 Mode

The deserialize x4 mode is used in high-speed applications where the FPGA fabric cannot operate as fast as the TX PCS.

In deserialize x4 mode, the byte deserializer deserializes 8-bit data into 32-bit data. As the parallel data width from the word aligner is quadrupled, the clock rate is divided four times.
