Abstract
A hybrid output driver includes a voltage mode main driver and a current mode emphasis driver that provides an adjustable differential output voltage swing. The current mode emphasis driver provides: push-pull swing control currents in response to a cursor data value, push-pull precursor currents in response to a precursor data value, and push-pull postcursor currents in response to a postcursor data value. In a normal operating mode, the swing control currents oppose voltages imposed by the voltage mode main driver on the differential output terminals. In a turbo operating mode, the swing control currents enhance voltages imposed by the voltage mode main driver on the differential output terminals.
