Abstract
A multi-phase partial response equalizer is disclosed. The equalizer includes receiver circuitry to receive a data symbol over N bit intervals and to generate N sets of samples in response to N clock signals having different phases. A first storage stage is provided, including storage elements to store the sets of samples during a common clock interval. First and second selection circuits are respectively coupled to an input and an output of the first storage stage. An output storage stage is coupled to the second selection circuit to store an output sample. The first and second selection circuits, over multiple clock intervals, cooperatively select the output sample from one of the sets of samples based on a most recent previous output sample.
