AGC filter
IF AGC filter connection.
The AGC voltage is created by smoothing the signal
that results from peak detection by the AGC detector at
pins 17 (first AGC), and 15 and 16 (second AGC).
The video signal input to this IF AGC detector is a
signal that was passed through the audio trap circuit.
18
19
VIF input
VIF amplifier input.
The input circuit is a balanced input, and its input
impedance is due to the following component values.
R =1.5k
Ω
C = 3pF
20
GND
21
RF AGC VR
RF AGC adjustment.
This pin sets the tuner's RF AGC operating point.
Both the FM output and the video output can be muted
by setting this pin to the ground level.
