Zusammenfassung:In one embodiment, a voltage mode driver circuit includes a first voltage adjusting circuit configured to provide an adjustable first pseudo-supply voltage to a first node based on a first supply voltage, including generating the first pseudo-supply voltage based on a first reference voltage and feedback from the first node. In this embodiment, the voltage mode driver circuit includes switching circuitry configured to selectively couple one of the first node or a second node to a first differential output terminal and a different one of the first node or the second node to a second differential output terminal based on a data signal. In this embodiment, the voltage mode driver circuit includes a current mode emphasis driver configured to selectively couple one of the first differential output terminal or the second differential output terminal to a first set of one or more current supplies and a different one of the first differential output terminal or second differential output terminal to a second set of one or more current supplies, based on one or more emphasis signals.
