SYSTEM OF OPTIMIZING A HIGH-SPEED LINK INCLUDING A CHANNEL CARRYING A DATA SIGNAL BETWEEN A TRANSMITTER AND A RECEIVER AND METHOD THEREOF AND METHOD OF CHARACTERIZING A CHANNEL BETWEEN A TRANSMITTER AND A RECEIVER

摘要

A method for characterizing a channel between a transmitter and a receiver is provided. The method comprises the following steps of: 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 in a different equalizer setting. Based on such characteristics, an optimal equalizer setting can be selected among a plurality of equalizer settings on the basis of the channel ISI PDF and an equalizer response function.
