Abstract:
This article presents a background adaptive crosstalk (XT) equalization technique for a single-endedfour-level pulse amplitude modulation (PAM-4) interface to maintain accurate XT cancellation (XTC) under environmental variations. A least-mean-square (LMS) adaptation loop adjusts the XT equalizer using a source-synchronous clock as an aggressor reference uncorrelated with the victim. At the …
