Abstract

An apparatus comprising a decision circuit, a detector circuit and a processing circuit. The decision circuit may be configured to generate a confirmation signal in response to a first lock signal and a second lock signal. The detector circuit may be configured to generate the first lock signal in response to a filtered version of an input signal being above a threshold. The processing circuit may be configured to generate the second lock signal in response to a power signal received from the detector circuit. The processing circuit generates the second lock signal by analyzing the rising edge of a frequency power envelope of the power signal.
