Abstract
A SerDes receiver device can receive binary signals via wireline channel such that information recovery is primarily or entirely performed via DSP algorithms in the digital domain includes an analog to digital converter, adaptation and calibration blocks, and a sequential n-way parallel equalization data path. The data path provides preliminary equalization of digital input symbols through a feed forward equalizer block followed by a decision feedback equalizer block, to which a k-slice decision feed forward equalizer block is appended for generating equalized hard decision outputs. The decision feed forward equalizer block may include a concatenation of cascading DFFE slices to improve the performance of the data path.
