1. An integrated circuit having a pin adapted for electrical communication with a signaling path to receive an electrical input signal therefrom, comprising:

  • a first circuit operable to receive bits associated with a first data cycle of the electrical input signal and operable to produce a decision regarding logic state of the bits associated with the first data cycle;

    a second circuit operable to receive bits associated with a second cycle of the electrical input signal and operable to produce a decision regarding logic state of the bits associated with the second data cycle; and

    an equalizing circuit operable to compensate for intersymbol interference affecting the second circuit dependent on an output of the first circuit and operable to compensate for intersymbol interference affecting the first circuit dependent on an output of a circuit other than the first circuit operable to produce a decision regarding logic state of bits of the electrical input signal.
