Abstract
A technique for terminating a differential signal line substantially matches the output impedances of a first node and a second node of a differential node. The power dissipation is substantially less than twice the power delivered to a load impedance coupled to the differential signal line. The technique provides a peak-to-peak, single-ended output voltage on the differential output node that is substantially independent of integrated circuit manufacturing process tolerances. An apparatus includes a differential node coupled to provide a differential signal. The differential node includes a first node and a second node. A first single-ended termination circuit is coupled to the first node and responsive to a first reference voltage. The apparatus includes a second single-ended termination circuit coupled to the second node and responsive to a second reference voltage.
