  • Serial digital audio data port with multiple functional configurations
    Patent number: 6744276
    Abstract: A bidirectional serial port for digital audio data includes a cable connector for coupling the port to a cable, a cable driver having a serial digital audio signal as an input and also having an output, a receiver having an input and an output, and an impedance and level matching network coupled to the output of the cable driver, the input of the receiver, and the cable connector. The port can be selectively configured either as an input port by causing the impedance and level matching network to act as a cable termination or as an output port by allowing the serial digital audio signal to pass through the cable driver and the impedance and level matching network to the cable connector.
