ABSTRACT:
An electrical idle detection circuit including a full wave rectifier and a first amplifier. The full wave rectifier is configured to receive differential input signals and provide a rectified output signal based on the differential input signals. The first amplifier is configured to receive a first input signal based on the rectified output signal and a second input signal based on a reference signal. The first amplifier is configured to provide an output signal that indicates the differential input signals are one of active and in electrical idle based on the first input signal and the second input signal.
