PARTIAL RESPONSE DECISION-FEEDBACK EQUALIZATION WITH ADAPTATION BASED ON EDGE SAMPLES

摘要

A device (102) implements data reception with edge-based partial response decision feedback equalization. The device implements a tap weight adapter circuit (114) that sets the tap weights that are used for adjustment of a received data -signal (104). The tap weight adapter circuit (114) sets the tap weights based. on previously determined data values and input from an edge analysis of the received data signal using a set of edge samplers. The edge analysis (116) may include adjusting the sampled data signal by the tap weights determined by the tap weight adapter circuit. A clock generation circuit (220) generates an edge clock signal to control the edge sampling performed by the set of edge samplers. The edge clock signal is generated as a function of the signals of the edge samplers and prior data values determined by the equalizer.
