An energy efficient (0.068pJ/b/dB) NRZ wireline transceiver is presented that leverages 3-tap FFE in the transmitter and feature extraction with classification in the receiver for compensating 30dB to 47dB channel loss with BER-11. The proposed random forest classifier learns long-reach channel characteristics enabling the transceiver to achieve 3.2pJ/b at 25Gb/s for compensating 47dB loss.
