Abstract
A differential pair contact resistance asymmetry compensation system includes a board with a differential trace pair. A receiver device is coupled to the differential trace pair via a receiver device connector interface, and a transmitter device is coupled to the differential trace pair via a transmitter device connector interface. The transmitter device transmits a contact resistance compensation data stream to the receiver device via the differential trace pair. The transmitter device then adjusts an impedance provided by the transmitter device to compensate for a contact resistance asymmetry in the transmitter device connector interface. When the transmitter device determines that differential trace pair signal transmission capabilities for the differential trace pair in transmitting the contact resistance compensation data stream have improved in response to the adjustment of the impedance provided by the transmitter device, it sets the impedance provided by the transmitter device.
