Abstract
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.
