摘要
A method and apparatus is disclosed that is capable of transmitting video signals and/or audio signals using the HDMI interface standard or the DisplayPort interface standard. A dual mode transmitter is disclosed that is configurable to transmit to a first sink device, configured in accordance with a HDMI display interface, in a HDMI mode of operation and/or a second sink device, configured in accordance with a DisplayPort display interface, in a DisplayPort mode of operation. The dual mode transmitter is configured to receive a biasing current from the first sink device in the HDMI mode of operation or to internally provide the biasing current in DisplayPort mode of operation by selecting impedances from selectable impedance networks. The dual mode transmitter is configured to transmit the video signals and/or audio signals by biasing one or more transistors using the biasing current.
