FUNCTION
INTERFACE CIRCUIT
1
2
AGC Filter
This filter is a dual time constant system to
speed up AGC.
By connecting the primary filter terminal of
pin 2 to GND, the picture muting is
executed.
3
AGC Delay
This terminal adjusts the delay point of RF
AGC by varying the reference voltage of
comparator.
4
5
PIF Input
This is an input terminal of PIF signal using
an emitter follower.
The input impedance is typical 2.5k, 4pF.
6
PIF GND
GND pin for the PIF amplifier.
Connect a capacitor between pins 23 and 6.

7
RF AGC Output
Output pin for RF-AGC supplied to the tuner.
(A 39k resistor is connected internally
between pin 7 and the internal power supply
pin.)
