Abstract
Various embodiments provide for quarter-rate data sampling with loop-unrolled decision feedback equalization (DFE) that uses a two-summer (e.g., two-summing node) approach. For example, some embodiments provide for quarter-rate data sampling comprising a plurality of unrolled first-tap DFE loops, and two summers and a two-to-one multiplexer for each of the other tap loops used for direct feedback (e.g., second tap, third tap, fourth tap, etc.)
