VIF input
18
Input for the VIF amplifier.
The input circuit creates an averaged input and has an input
impedance determined by the following resistor and ¹⁹
capacitor values.
R ≈ 1.5 kΩ
C ≈ 3 pF
20 GND
A12066
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 be muted at the same
time by shorting this pin to ground.

22 First SIF output
A 600-Ω resistor is attached to the emitter follower internally
for signal output. When an intercarrier sound system is
used, the buzz characteristics can be improved by forming a
chrominance carrier trap on this pin.
