Abstract
A system for receiving signals transmitted via serial links includes an analog-to-digital converter configured to sample the first analog signal at a first rate, and generate a first digital input signal having a second data rate. The system also includes a decimator coupled to an output of the equalizer and configured to downsample the first equalized signal to a decimated signal having the first data rate. The system further includes a fast equalization module for determining output data corresponding to the communications signal. The fast equalization module includes a filter to access an output of the equalizer, a second slicer module to access an output of the filter and produce a data output corresponding to the communications signal, a lookup table to provide filtering coefficients to the filter, and a coefficient improvement module to improve the coefficients based on an error signal from the filter.
