Abstract
Various embodiments provide a method or system that implements a two-tap decision feedback equalizer by applying a first tap and a second tap on a first symbol of a data signal, each of the first and second taps having a first and second polarity to generate a first corrected data symbol and a second corrected data symbol. The first corrected data symbol and the second corrected data symbol is provided to a comparator to select a data symbol. The output of the comparator is provided to a clock data recovery circuit along with a previous data symbol of the data signal preceding the first data symbol.
