An encoding and/or decoding communication system comprises a framer
interface, an encoder, a multiplexer, an output driver, and a clock
multiplier unit (CMU). The encoder includes an input latch circuitry
stage; an output latch circuitry stage; an intermediate latch circuitry
stage interposed between the input latch circuitry stage and the output
latch circuitry stage, the intermediate latch circuitry stage coupled to
the input latch circuitry stage and the output latch circuitry stage; a
plurality of encoding logic circuitry stages interposed between the input
latch circuitry stage and the output latch circuitry stage, a last one of
the plurality of encoding logic circuitry stages placed adjacent to the
output latch circuitry stage and coupled to the output latch circuitry
stage; and a feedback between the output latch circuitry stage and the
last one of the plurality of encoding logic circuitry stages.
