US 2006/0215792 A1 · Minimizing dynamic crosstalk-induced jitter timing skew

Abstract

A digital signal waveform receiving circuit may be processed by a non-linear adaptive canonical correlation analysis circuit that may quantify and minimize crosstalk-induced jitter timing skew for improving set-up and hold timing margins of data streams on the receiving circuit. A non-linear adaptive canonical correlation analysis circuit may be placed between an incoming digital signal from a serial link and a PHY receiving layer of an information handling system 100. The PHY receiving layer of the information handling system may be coupled to the non-linear adaptive canonical correlation analysis circuit or may be coupled to the digital signal. This coupling selection may be automatically programmed depending on received signal cross-talk-induced jitter timing skew or may be programmed by a user of the information handling system.
