Patent ID: 7817586

Claim:
A first high-speed digital interface transceiver for transmitting or receiving high-speed data, wherein the high-speed digital interface transceiver comprises: a transmitter; a receiver; a first multiplexer for selectively coupling to the transmitter or the receiver, wherein the first high-speed digital interface transceiver acts as a source device while the first multiplexer is coupled to the transmitter, and the first high-speed digital interface transceiver acts as a sink device while the first multiplexer is coupled to the receiver; and a controller, coupled to the first multiplexer, for controlling a switching operation of the first multiplexer; wherein the first high-speed digital interface transceiver is acted as a bi-directional communication device to support both functions of the source device and the sink device, and the first high-speed digital interface transceiver is pre-set to be either the source device or the since device prior generating a first control switching command.
