Abstract
A receiver module includes an automatic gain control module having a gain that varies from a nominal value in response to the receiver module receiving an input signal. The automatic gain control module is configured to generate a first signal in response to the gain settling at a value different from the nominal value. A peak detector module is configured to generate a second signal in response to the gain deviating from the nominal value by a predetermined amount. The peak detector module generates the second signal prior to the automatic gain control module generating the first signal. A control module is configured to receive each of the first signal and the second signal and reset the receiver module to halt processing of the input signal in response to the control module not receiving the first signal within a predetermined amount of time subsequent to the control module receiving the second signal.
