The 8B10B encoder converts an 8-bit wide word to a 10-bit wide word. The complete
list of codes can be found in the DVB-ASI EN50083-9 standard.
A control code input inserts comma characters (K28.5) when no data is available at the
input of the encoder.
The transceiver can be either a serializer for soft-logic implementations, or GX
transceivers.
