DIFFERENTIAL SIGNAL TERMINATION CIRCUIT

A multi-mode differential termination circuit has a pair of differential input terminals for receiving external differential signals, a pair of series-connected load elements coupled between said differential input terminals, and an analog interface terminal coupled a common junction point of said load elements. A bias circuit is coupled to the common junction point of the load elements for selectively applying a bias voltage thereto in response to a digital control signal. A control input receives the digital control signal to activate the bias circuit.
