SYSTEM AND METHOD OF LINK OPTIMIZATION

摘要

A method of characterizing a channel between a transmitter and a receiver (e.g., in a high-speed link) is presented. The method comprises: determining an overall intersymbol interference (ISI) probability density function (PDF) from eye monitor data obtained for a current equalizer setting, extracting a channel ISI PDF for the current equalizer setting from the overall ISI PDF, and generating an overall ISI PDF for a different equalizer setting by using the channel ISI PDF for the current equalizer setting and an impulse response at the different equalizer setting. Based on this characterization, an optimal equalizer setting may be selected among a plurality of equalizer settings on the basis of the channel ISI PDF and the equalizer response functions.
