FM mute ON Adj
Limited amplifier input
Select the capacitor grounding point
carefully.
The muting time constants from the
external CR circuit are determined as
follows.
Attack time TA = R1 × C2
Release time TR = R2 × C2
Noise convergence adjustment
Divide the V23 voltage by R2 when
there is no input at the antenna input,
and input that voltage to pin 22.
Noise convergence will be maximum
when V22 = 2 V.
The variation range is 5 to 35 dB,
taking the 1 kHz 22.5 kHz dev output
as the reference.
Muting off function
The muting is turned off when pin 22 is
shorted to ground.
The muting on level is adjusted by changing
the external resistance R.
