PIN NAME
FUNCTION
9 SIF Input
Connect BPF between this terminal
and pin 23.
10 SIF VCC
11 N.C.
12 Video Adjust
13 SIF GND
Connect bypass capacitor between
this terminal and SIF GND with
shortest wiring.
―
Video signal output voltage adjustment
terminal.
Chaging this terminal voltage, it is
possible to adjust video signal output
voltage to 1.0 Vp-p.
(In case of use on adjustment free,
connect resistor (330 kΩ) (*) to GND.)
To prevent noise, connecting capacitor
(0.01 µF) to GND is recommended.
(*resistance tolerance : ±5%)
Connect bypass capacitor between
this terminal and SIF VCC with
shortest wiring.
14 AFT Output
AFT detector output terminal based on
double balanced multiplier.
AFT output is muted when AFT coil
terminal is connected to GND.
