1. An apparatus comprising:
a crosstalk cancelation circuit comprising:
a plurality of taps to output signals based on a signal transmitted via a first data line, wherein the plurality of taps comprise a plurality of delay blocks coupled to the first data line, wherein an output of a delay block of the plurality of delay blocks is coupled to an input of a gain block of a plurality of gain blocks of the plurality of taps; and
a summation circuit to combine a signal received by a second data line with the signals output by the plurality of taps to reduce near-end crosstalk present in the signal received by the second data line.
