Description
Equivalent circuit
21
RF AGC VR
RF AGC VR connection.
This pin sets the tuner RF AGC operating point. Also, the
FM output and the video output can both be muted at the
same time by connecting this pin to ground.
22
NICAM output
First SIF output.
Internally, this is an emitter-follower output with a 600-
resistor attached. When used in an intercarrier system, the
buzz characteristics can be improved by forming a
chrominance carrier trap with this pin.
Forms a chrominance killer trap.
23
FM filter
Connection for a filter used to hold the FM detector output
DC voltage fixed. Normally, a 1-μF electrolytic capacitor
should be used. The capacitance should be increased if
the low band (around 50 Hz) frequency characteristics
need to be improved.
24
FM Detector output
Audio FM detector output. A 300-
resister is inserted in
series with an emitter-follower output.
For applications that support stereo:
Applications that input this signal to a stereo decoder may
find that the input impedance is reduced, the left and right
signals are distorted, and that the stereo characteristics are
degraded. If this problem occurs, add a resistor between
pin 24 and ground.
R1
≥
5.1 k
For applications that support mono:
Create an external deemphasis circuit.
