XAUI Mode
The transmit state machine translates the XAUI XGMII code group to the
XAUI PCS code group.
The XAUI PCS idle code groups, /K28.0/ (/R/) and /K28.5/ (/K/), are
automatically randomized based on a PRBS7 pattern with an x
polynomial. The /K28.3/ (/A/) code group is automatically generated
between 16 and 31 idle code groups. The idle randomization on the /A/,
/K/, and /R/ code groups are done automatically by the transmit state
machine.
Serializer (Parallel-to-Serial Converter)
The serializer converts the parallel 8-bit or 10-bit data into a serial stream,
transmitting the LSB first. The serialized stream is then fed to the transmit
buffer.
