Abstract
An output driver with programmable single-ended and differential outputs includes a first switch, a first output attenuator, and a programmable attenuator. The first switch is coupled in a shunt configuration to a first path of a differential output of a first amplifier. The first output attenuator is included in the first path and is coupled to the first switch in accordance with the shunt configuration. The programmable attenuator is included in a second path of the differential output of the first amplifier.
