Abstract

See full text

A system adjusts a voltage swing of an output driver based on a supply voltage. A supply voltage monitor generates a digital code indicating the difference between the supply voltage and nominal voltage representing a preferred level for the supply voltage. An impedance controller sets the voltage swing for the output driver based on the digital code, thereby keeping the voltage swing of the output driver output signal within specified limits while maintaining an impedance match with a load coupled to the output driver.
