1. A device comprising:

  • hybrid circuitry coupled to a communication interface circuitry, the communication interface circuitry configured to transmit first analog signals over a communication link and receive second analog signals over the communication link;

    transmitter circuitry coupled to the communication interface circuitry via the hybrid circuitry, the transmitter circuitry configured to convert first digital data to the first analog signals and provide the first analog signals to the hybrid circuitry for transmission over the communication link via the communication interface circuitry; and

    receiver circuitry coupled to the communication interface circuitry via the hybrid circuitry, the receiver circuitry configured to receive the second analog signals from the hybrid circuitry, the second analog signals having been received over the communication link via the communication interface circuitry,wherein the hybrid circuitry is configured to use the first analog signals provided by the transmitter circuitry to cancel the first analog signals that are coupled into the second analog signals received over the communication link via the communication interface circuitry.
