Abstract:
A serial communication circuit (FIG. 3) is disclosed. The circuit includes an equalizer circuit (306) arranged to receive a data signal (CH 1) and produce an equalized data signal. A log detector circuit (300) receives the data signal and produces a power signal indicating a power level of the data signal. A decision circuit (332) receives the power signal and produces a select signal. A first selection circuit (336) receives a plurality of first correction signals and applies one of the first correction signals to the equalizer circuit in response to the select signal.
