The GTM receiver supports pre-coding. Pre-coding can be used to reduce receiver DFE error propagation by reducing 1-tap burst error runs into two errors for every error event. The RX pre-coder has independent endianness control blocks. The following figure shows the sequence in which bits are flipped.
