Pin No.
Pin
Function
Equivalent circuit
Output for the video signal that includes the SIF carrier
A resistor must be inserted between pin 10 and ground to
assure adequate drive capabilities.
R
≥ 300
10
Conposite video output
Connections for the VCO tank circuit used by the video
detector. See the coil specifications for the tank circuit
provided separately. This VCO is a vector synthesis VCO.

AFT output
The AFT center voltage is created by an external bleeder
resistor. The AFT gain increases as the value of this bleeder
resistor increases. This resistor must not exceed 390 k
.
This circuit includes a function that controls the AFT voltage
to naturally approach the center voltage during weak field
reception.

AFT OUTPUT
RF AGC output
This signal controls the tuner RF AGC.
This is an emitter output with a 200
protective resistor
inserted in series. Determine the value of the external
bleeder resistor according to the specifications of the tuner.
