Abstract
A system and a method are provided for multiplexing digital and analog signals to and from a device using a single electrical connector. The system includes a connector with at least four lines and analog and digital interfaces attached to the connector. The interfaces share: first and second analog-to-digital converters (ADCs); and first, second, and third switches. The analog interface includes an audio sub-system with a third ADC and first, second, and third digital-to-analog converters (DACs). The digital interface includes a digital sub-system. The switches have first terminals attached to the connector, second terminals connected to the third ADC and the DACs. The switches open in response to a digital mode signal, enabling a digital signal path from the digital interface terminals to the connector. The switches close in response to an analog mode signal, enabling an analog signal path from the connector to the audio sub-system.
