1. Apparatus for processing an M-level signal, M>

  • 2, comprising;

    (a) a plurality of data slicers, each adapted to data sample the M-level signal relative to a threshold level between a different adjacent pair of symbol levels;

    (b) two or more edge slicers, each adapted to edge sample the M-level signal relative to a threshold level between a different adjacent pair of symbol levels;

    (c) a clock generator adapted to generate at least one clock signal based on outputs from the two or more edge slicers, wherein the at least one clock signal determines the timing of the data sampling of the M-level signal by at least one of the plurality of data slicers.
