Abstract:
A device, comprising:a first input pin adapted to receive a first differential component of a signal; a second input pin adapted to receive a second differential component of the signal; a differential signal generator coupled to the first and second input pins and adapted to receive an enable signal, wherein the differential signal generator includes logic adapted to isolate the second input pin and generate an internal differential signal component based on an inversion of the first differential component of the signal in response to the enable signal being asserted; and a differential receiver having a first input terminal and a second input terminal and being adapted to receive the first differential component of the signal at the first input terminal and one of the second differential component of the signal and the internal differential signal component at the second input terminal and generate an output signal having a high logic level responsive to a voltage at the first input terminal being greater than a voltage at the second input terminal and a low logic level responsive to the voltage at the first input terminal being less than the voltage at the second input terminal.
