Equivalent circuit
FM filter
Connection for a filter used to hold the FM detector output at
a fixed DC voltage.
Normally, a 1-F electrolytic capacitor is used. If the low
area (around 50 Hz) frequency characteristics are seen as a
problem, this capacitance should be increased.
The FM detector output level can be reduced and the FM
dynamic range can be increased by inserting a resistor and
a capacitor in series between pin 23 and ground.

FM detector output
Audio FM detector output.
A resistance of 200
is inserted in series with the emitter
follower.
In applications that support stereo:
In applications that input to a stereo decoder, the reduced
input impedance can cause distortion in the L-R signal. This
may degrade the stereo characteristics. If this is a problem
add the resistor R1 between pin 24 and ground.

≥ 5.1 k
In applications that support mono:
Attach an external de-emphasis circuit with the following
time constant.
