Abstract
A cable detection circuit for a device, set forth by way of example and not limitation, includes a generator circuit operative to provide currents on a line of a communication interface. A controller is coupled to the generator circuit and operative to detect an amount of capacitance on the line based on the provided currents. The controller is operative provide an output based on the detected amount of capacitance, the output indicating whether a cable is connected to the device via the communication interface.
