Apparatus, system and method for providing switching with a T-coil circuit

摘要

Techniques and mechanisms for switching between a plurality of inputs each to receive a respective analog signal to be transmitted. In an embodiment, switch circuitry comprises a first input to receive a first signal, a second input to receive a second signal, and one or more T-coil circuits including a first T-coil circuit. A first configuration of the switch circuitry includes a first signal path via a first switch coupled between the first input and a primary input node of the first T-coil circuit. A second configuration of the switch circuitry includes a second signal path via a second switch coupled between the second input and a secondary input node of the first T-coil circuit. In an embodiment, control logic transitions the switch circuitry among a plurality of configurations including the first configuration and the second configuration.
