Abstract
A system and method for decision feedback equalization of a crossing slicer. A serial receiver includes a data slicer and a crossing slicer, and implements decision feedback equalization for the data slicer, with a plurality of data weights. The serial receiver also implements decision feedback equalization for the crossing slicer, using crossing weights that are interpolated between corresponding pairs of the data weights. The crossing weights may be formed by any suitable interpolation method, including linear interpolation, cubic interpolation, or spline interpolation.
Claims20
A method for operating a digital link, the method comprising:
- processing an input signal by a data slicer and a data decision feedback equalizer (DFE), the data DFE comprising a plurality of data weights;
- and
- processing the input signal by a crossing slicer and a crossing DFE, the crossing DFE comprising a plurality of crossing weights,
- a crossing weight of the plurality of crossing weights being equal to a value interpolated between a first data weight of the plurality of data weights and a second data weight of the plurality of data weights of data weights.
A system for receiving serial data, the system comprising:

- a data decision feedback equalizer (DFE) with a plurality of data weights;
- a crossing slicer;
- and
- a crossing DFE with a plurality of crossing weights,
- a crossing weight of the plurality of crossing weights being equal to a value interpolated between a first data weight of the plurality of data weights and a second data weight of the plurality of data weights of data weights.
