MC3371 MC3372  
An external positive bias to Pin 12 sets up the squelch  
Another possible application of the squelch switch may  
be as a carrier level triggered squelch circuit, similar to the  
MC3362/MC3363 FM receivers. In this case the meter  
output can be used directly to trigger the squelch switch  
when the RF input at the input frequency falls below the  
desired level. The level at which this occurs is determined  
by the resistor placed between the meter drive output  
(Pin 13) and ground (Pin 15).  
trigger circuit such that the audio mute (Pin 14) is open or  
connected to ground. If Pin 12 is pulled down to 0.9 V or  
below by the noise or tone detector, Pin 14 is internally  
shorted to ground. There is about 57 mV of hyteresis at  
Pin 12 to prevent jitter. Audio muting is accomplished by  
connecting Pin 14 to the appropriate point in the audio path  
between Pin 9 and an audio amplifier. The voltage at Pin 14  
should not be lower than –0.7 V; this can be assured by  
connecting Pin 14 to the point that has no dc component.
