Abstract

See full text

A 1/n-rate decision feedback equalizer (DFE) and method include a plurality of branches. Each branch includes a separate summer circuit configured to add a respective feedback signal to a received input and a latch configured to receive an output of the summer circuit to provide different partial bit sequences based on a clock signal. A feedback circuit includes a multiplexer configured to multiplex the different partial bit sequences of each branch to assemble a full rate bit sequence and a filter configured to provide cancellation of intersymbol interference (ISI) from the received input.
