Abstract
An integrated circuit (IC) includes a plurality of pads adapted to communicate signals with a circuit external to the IC, and a first mixed signal interface block coupled to a first pad in the plurality of pads, where the first mixed signal interface block is adapted to receive a first trigger signal from the circuit external to the IC and to provide a second trigger signal. The IC further includes a second mixed signal interface block coupled to a second pad in the plurality of pads, where the second mixed signal interface block is adapted to receive and track a first input signal from the circuit external to the IC in a first mode of operation of the IC. The second mixed signal interface block is further adapted to generate, in response to the second trigger signal, a first output signal based on the first input signal and to provide the first output signal to a digital core of the IC in a second mode of operation of the IC, where the power consumption of the IC is lower in the first mode of operation than in the second mode of operation.
