Composite video output
Output for the video signal that includes the SIF carrier.
To acquire adequate drive capabilities, a resistor must be
inserted between pin 10 and ground.
R
≥ 300

12
VCO tank
This is the VCO tank circuit used for the video detector.
Refer to the coil specifications provided separately for more
information on the tank circuit. This VCO is a vector
synthesis VCO.
13
AFT output
The AFT center voltage is created by an external bleeder
resistor. The AFT gain increases as the value of this
external bleeder resistor is increased. Note that the value of
this resistor must not exceed 390 k
.
This circuit includes a control function that naturally brings
the AFT voltage to its center value under weak field
reception conditions.
14
RF AGC output
This output controls the tuner RF AGC.
There is a 200-
series protection resistor inserted in the
emitter output. Determine the value of the external bleeder
resistor based on the characteristics of the tuner used.
