Abstract
Provided herein are systems and methods for transmitting signals across a pair of wires. In accordance with specific embodiments, a differential signal is transmitted across the pair of wires during one period of time, and two single-ended signals are transmitted across the same pair of wires during another period of time. Low voltage differential signaling (LVDS) can be used to transmit the differential signal across the pair of wires. In contrast, non-differential signaling can be used to transfer the two singled-ended signals across the same pair of wires.

14. A system, comprising:
-
a transmitter including a pair of outputs; and a receiver including a pair of inputs; wherein the pair of outputs of the transmitter are configured to be connected, by a pair of wires, to the two inputs of the receiver; wherein the transmitter, when in a first mode, outputs a differential signal at the two outputs to transmit across the two wires to the two inputs of the receiver; and wherein the transmitter, when in a second mode, outputs two single-ended signals, one at each of the two outputs, to transmit across the same two wires to the two inputs of the receiver. - View Dependent Claims (15, 16, 17, 18, 19)
