An equalizer generates an equalized sample from a plurality of received samples in which a forward equalizer filters a received sample to generate a FE output. A feedback equalizer filters the equalized sample to generate a FBE output. An integrator adds the FE and FBE outputs to generate the equalized sample. The feedback equalizer comprises first and a second sub-filters. The first sub-filter has a first bit-width capability to generate a first FBE output from the equalized sample. The second sub-filter has a second bit-width capability to generate a second FBE output from the equalized sample. The first bit-width is higher than the second bit-width, and the first and second FBE outputs jointly organize the FBE output.
