Serializer
The serializer converts the incoming low-speed parallel signal from the transceiver
PCS to high-speed serial data and sends it to the transmitter buffer. The serializer
supports an 8-bit or 10-bit serialization factor in single-width mode and a 16-bit or
20-bit serialization factor in double-width mode. The serializer block drives the serial
data to the output buffer, as shown in
LSB of the input data.
