Abstract
A physical layer transceiver, for connecting a host device to a wireline channel medium that is divided into a total number of link segments, includes a host interface for coupling to a host device, a line interface for coupling to the wireline channel medium, and feed-forward equalization (FFE) circuitry operatively coupled to the line interface to add back, into a signal, components that were scattered in time. Respective individual filter segments are selectably configurable, by adjustment of respective delay lines, to correspond to respective individual link segments. The FFE circuitry also includes control circuitry configured to detect a signal energy peak in at least one particular link segment and, upon detection of the signal energy peak in the particular link segment, configure a respective one of the respective individual filter segments, by adjustment of a respective delay line, to correspond to the respective particular link segment.
