Zusammenfassung:An apparatus is provided which comprises: a data sampler coupled to an output of a driver, wherein the data sampler is to sample data and to compare it with a first threshold voltage and a second threshold voltage, and wherein the data sampler is to generate an up or down indicator according to comparing the data with the first and second threshold voltages; and logic coupled to the data sampler, wherein the logic is to receive the up or down indicator and to increment or decrement a number of already DC compensated impedance legs of the driver according to the up or down indicator.
