1. A method of slicing a data signal comprising:

  • clamping the data signal to a reference level;

    applying the clamped data signal to one input of a comparator to produce a sliced output;

    sampling the sliced output of the comparator with a high frequency dot clock to produce a series of positive and negative logic levels;

    applying the series of positive and negative logic levels to a D/A converter;

    filtering the output of the D/A converter to develop a DC voltage; and

    applying the DC voltage to the other input of said comparator to adjust the slice level of the comparator.
