An apparatus includes a first squelch circuit and a second squelch circuit. The first squelch circuit is configured to detect possible squelch signals in a communication signal. The second squelch circuit is configured to selectively detect the possible squelch signals in the same communication signal. The second squelch circuit is further configured to operate in a low-power state responsive to the first squelch circuit detecting none of the possible squelch signals in the communication signal. The second squelch circuit is further configured to operate in a high-power state responsive to the first squelch circuit detecting one of the possible squelch signals in the communication signal.
