Abstract
A combined output driver for TMDS signals and LVDS signals. A first output driver includes a first differential unit generating a first differential according to first input signals in a first mode and a first clamping device coupled between the first node and the first differential unit to clamp potentials at two power terminals below a second power voltage. The second output driver includes a second differential unit generating a second differential signal according to second input signals in a second mode and a second clamping device to clamp potentials at two output terminals of the second differential unit below the second power voltage.
