Abstract
A device having a voltage mode driver with tunable amplitude and resistance that supports a predetermined output resistance and output amplitude is described herein. The voltage mode driver includes multiple configurable drivers. The voltage mode driver is controlled by a control module. Resistance tuning is controlled by the number of active configurable drivers and amplitude tuning is controlled by setting the high or low drive state of each active configurable driver. The slew rate of the device is controlled by delaying the setting of the high or low drive state of an active configurable driver by a predetermined interval.
