A 40-Gb/s CDR Circuit With Adaptive Decision-Point Control Based on Eye-Opening Monitor Feedback

40-Gb/s clock and data recovery (CDR) circuit with an integrated high-precision eye-opening monitor (EOM) circuit and an adaptive control scheme for optimizing the data decision point are presented. An adaptive decision-point control (ADPC) scheme using the EOM feedback overcomes the time-varying wa...
