Circuit Configuration

Description

Pins 13 and 14 are the VCO tank circuit.

VCO coil recommended

. Japan 1.2 µH

. U.S.

1.8 µH

Make the circuit pattern between the IC and

the coil as short as possible.

15 VIDEO OUTPUT

Pin 15 is the SIF carrier (4.5 MHz)-contained

video output pin. The level of the video

output is approximately 1.5 Vp-p.

16 APC1 FILTER

Pin 16 is the APC1 filter pin. The filter

smoothes the output after comparing the

phase of the IF signal with that of VCO1 in

APC1.

C1 = 0.47 µF

R1 = 330 to 560Ω

C2 = 470 pF
