Abstract
A method to look at the incoming received data on a SerDes link while running in normal operation without requiring a second receive path or any defined or repeated data patterns to be able to generate statistical eye plots both before and after any internal equalization; generate trajectory eye plots both before and after any internal equalization; estimate TED characteristics (hence also estimate SJ jitter tolerance of the link); estimate complete Channel Impulse Response (hence also estimate the S-parameters of the complete channel); and estimate the decomposed jitter of the complete channel.
