Abstract
This article presents a four-level pulse-amplitude
modulation (PAM-4) transceiver targeting very-short-reach and
medium-reach (MR) electrical links. The receiver (RX) employs
a sample-based four-tap feed-forward equalizer (FFE) for pre-
and post-cursor inter-symbol interference (ISI) compensation.
The two-stage 16-way interleaving provides sufficient operation
time for FFE summation, which relaxes the bandwidth (BW)
requirement and improves power efficiency. The non-uniform
segmented three-tap FFE
