Abstract:
A differential pair contact resistance asymmetry compensation system includes a differential trace pair that is provided on a board, a transmitter device that is coupled to the differential trace pair via a transmitter device connector interface, and a receiver device that is coupled to the differential trace pair via a receiver device connector interface. The receiver device receives, from the transmitter device via the differential trace pair, a contact resistance compensation data stream. The receiver device adjusts an impedance provided by the receiver device to compensate for a contact resistance asymmetry in at least the receiver device connector interface, and sets the impedance provided by the receiver device.
