Abstract
A digital signal processing circuit comprises a first equalizer circuit and a second equalizer circuit. An output of the second equalizer is used as feedback to generate an equalized signal. The output of the second equalizer circuit is based on a plurality of postcursor values and a plurality of precursor values, where the precursor values are generated based on an output of the first DFE circuit, and the postcursor values are generated independently of the output of the first DFE.
