Function
Equivalent circuit
IF AGC filter connection
The AGC voltage is created at pin 17 from the peak detection
output produced by the internal AGC detector. A second
AGC filter (a lag-lead filter) is built in the IC to create a dual
time constant.
Use a 0.022-F capacitor as the external capacitor. Adjust
the value of the capacitor to compensate for sag, or modify
the AGC speed as required.

VIF amplifier input
The input circuit is a balanced input and the input impedance
corresponds to:
R
≈ 1.5 k and
C
≈ 3 pF.

RF AGC trimmer connection
This pin is used to set the tuner RF AGC operating point. The
FM and video outputs can be muted at the same time by
shorting this pin to ground.
