22.214.171.124.3. FGT Gray-Coder and Pre-Coder
Output lanes transmitting PAM4 map to gray-coded, pre-coded, or gray-coded and pre-coded PAM4 symbols. For NRZ signals, the gray-coder and pre-coder are bypassed.
For the FGT gray-decoder and pre-decoder, reverse the process for the FGT gray-coder and pre-coder.
