Abstract: A method and system for communicating data between two devices are described herein. The method detects an electrical signal of a first protocol from a first device in a repeater, wherein the first protocol comprises single-ended signaling. The method also determines the speed of the electrical signal. Additionally, the method converts the electrical signal of the first protocol into an electrical signal of a second protocol based on the speed of the electrical signal. The second protocol comprises differential signaling. Furthermore, the method sends the electrical signal of the second protocol to a second device. In addition, the method stops the electrical signal of the second protocol to the second device when the electrical signal of the second protocol indicates an end of data flow.

Abstract: A method for explicit control message signaling includes sending a single ended 1 signal on a pair of data lines, wherein the pair of data lines includes a first data line and a second data line. A voltage of the first data line is driven to a logic 1, while pulsing the voltage of the second data line between a logic 1 and a logic 0, wherein the pulses represent a control message.
