ABSTRACT:
A high-speed digital interface (HSDI) transceiver with bi-directional HSDI function includes a transmitter, a receiver, a first multiplexer, and a controller. The first multiplexer is selectively coupled to the transmitter or the receiver in order to let the HSDI transceiver act as a source device or a sink device respectively. The controller is coupled to the first multiplexer for controlling a switching operation of the first multiplexer. When the HSDI transceiver is connected to an HSDI source device, the controller controls the first multiplexer to couple to the receiver to let the HSDI transceiver act as the sink device, and when the HSDI transceiver is connected to an HSDI sink device, the controller controls the first multiplexer to couple to the transmitter to let the HSDI transceiver act as the source device.
