1. Circuitry to generate an interface signal between a first integrated circuit and a second integrated circuit comprising:

  • a reference circuit configured to provide a reference signal;

    an interface circuit implemented on the first integrated circuit and operatively coupled to the reference circuit, the interface circuit configured to receive the reference signal and a data input and to generate the interface signal in response thereto; and

    a circuit element implemented on the second integrated circuit and operatively coupled to the interface circuit, the circuit element configured to receive the interface signal and provide an output signal in response, wherein the interface signal is a differential current signal.
