Patent ID: 7391231

Claim:
A termination network for configuring the termination of first and second adjacent transmission lines for either two data line pseudo-differential signaling or single data line true differential signaling comprising: first circuitry coupled to the first transmission line and configured in response to a first logic state of a first control signal to terminate the first transmission line in a first impedance referenced to a first bias voltage for pseudo-differential signaling, the first circuitry comprising a first differential receiving device; second circuitry coupled to the second transmission line and configured in response to the first logic state of the first control signal to terminate the second transmission line in a second impedance referenced to a second bias voltage for pseudo-differential signaling, the second circuitry comprising a second differential receiving device; and third circuitry for coupling the first circuitry to the second circuitry thus configuring the first and second circuitry as a third impedance termination between the first and second transmission lines in response to a second logic state of the first control signal for true differential signaling.
