Patent ID: 8030967

Claim:
An apparatus comprising circuitry that comprises: a mode control section that is programmable to have one of first and second states; and a receiver section having first and second input terminals and having an output terminal, the receiver section being responsive to the mode control section for operating in a first operational mode when the mode control section has the first state and for operating in a second operational mode when the mode control section has the second state, wherein in the first operational mode the receiver section provides higher performance and consumes more power than in the second operational mode; wherein the receiver section includes first and second receiver circuits that each have first and second inputs respectively coupled to the first and second input terminals, and that each have an output coupled to the output terminal; wherein the first receiver circuit operates in each of the first and second operational modes; and wherein the second receiver circuit has an enable input coupled to the mode control section, the second receiver circuit being enabled and operating in the first operational mode, and being disabled in the second operational mode.
