摘要:
A decision feedback equalizer (DFE) circuit includes a first equalization path and a second equalization path. Each equalization path includes a summing node, a first latch, a second latch, a first feedback path, and a second feedback path. The first latch is configured to latch data received from the summing node. The second latch is configured to latch data received from the first latch. The first feedback path is configured to receive data from the second latch and to provide data to the summing node of the equalization path. The second feedback path is configured to receive data from the first latch and to provide data to the summing node of the other equalization path. The second feedback path provides up to a symbol interval for propagation of data between the summing nodes.
