Abstract

At least some aspects of the present disclosure provide for a method. In at least one example, the method includes applying first equalization to a received data signal to generate an equalizer signal and comparing the equalized signal to each of a plurality of reference voltages for a predetermined period of time per respective reference voltage to generate a comparison result. The method further includes determining a plurality of counts with each count of the plurality of counts uniquely corresponding to a number of rising edges in the comparison result for each of the plurality of reference voltages. The method further includes comparing at least one of the plurality of counts to at least another of the plurality of counts to determine a relationship among the plurality of counts and applying second equalization to the received data signal based on the determined relationship among the plurality of counts.
