1. An information handing system, comprising:
a transmitter configured to provide a differential signal on a pair of differential outputs, the transmitter including a first pull-down resistor coupled between a first one of the differential outputs and a ground plane of the information handling system, and a second pull-down resistor coupled between a second one of the differential outputs and the ground plane;
a receiver configured to receive the differential signal on a pair of differential inputs; and
a differential signal channel configured to carry the differential signal from the differential outputs to the differential inputs, the differential signal is provided on the differential signal channel as a voltage swing between a first positive voltage and a first negative voltage with reference to the ground plane.
