Modal PAM2/4 Pipelined Programmable Receiver Having Feed Forward Equalizer (FFE) And Decision Feedback Equalizer (DFE) Optimized For Forward Error Correction (FEC) Bit Error Rate (BER) Performance

摘要

A pipelined receiver comprises a programmable feed forward equalizer (FFE), a programmable decision feedback equalizer (DFE), and logic for controlling a ratio of FFE and DFE to apply to a received signal based on at least one channel parameter.
