PAST EQUALIZATION FOR JITTER MITIGATION
Last updated:
Abstract:
A system for receiving signals transmitted via serial links includes an equalizer for accessing a digitized communications signal and producing an equalized output signal, and 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 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 filer. The coefficient improvement module is configured to update the coefficients in the lookup table.
