LA75691
Function
Output for the video signal that includes the SIF carrier
10
Conposite video output
A resistor must be inserted between pin 10 and ground to
assure adequate drive capabilities.
R ≥ 300Ω
Equivalent 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 kΩ.
This circuit includes a function that controls the AFT voltage
to naturally approach the center voltage during weak field
reception.
RF AGC output
This signal controls the tuner RF AGC.
14
RF AGC OUTPUT
This is an emitter output with a 200Ω protective resistor
inserted in series. Determine the value of the external
bleeder resistor according to the specifications of the tuner.
