摘要： Dual-function drivers capable of outputting LVDS or TMDS differential signals by sharing output terminals under differential modes. In the dual-function driver, an input control unit receives a first input signal compliant with a first specification in a first mode and a second input signal compliant with a second specification in a second mode by sharing a pair of input terminals, and a current steering circuit comprises first and second differential pairs. The input control unit enables the first and second differential pairs to output a first differential signal compliant with the first specification through a pair of output terminals during the first mode, and the input control unit disables the first differential pair and enables the second differential pair to output a second differential signal compliant with the second specification on the pair of output terminals during the second mode.

The encoder encodes twenty eight bits of LVDS signals to thirty bits of TMDS signals. The serializer includes four serializer channels for converting the LVDS signals to a serial signal when a LVDS mode is enabled, or converting the TMDS signals to the serial signal when a TMDS mode is enabled. Wherein a first serializer channel is coupled to seven bits of the LVDS signals and outputting a first pair of differential signals. Second, third and fourth serializer channel are coupled to seven bits of the LVDS signals and ten bits of TMDS signals, and outputting a second, third and fourth pair of differential signals, respectively.

摘要： A combined output driver for TMDS signals and LVDS signals. First and second output drivers output first and second differential signals to a first external input unit and a second external input unit, respectively, through a pair of signal lines according to first and second input signals. In the second output driver, a driver buffer is coupled to a first voltage and a first node respectively to generate two control signals according to the second input signals. An output unit generates the second differential signal according to the two control signals. A power supply provides a second voltage higher than the first voltage to power the driver buffer and the output unit when the first output driver outputs the first differential signal to the first external input unit.
