Description
VCO COIL
Pins 13 and 14 are the VCO tank circuit.
VCO coil recommended
.
Japan
1.2 μH

1.8 μH
Make the circuit pattern between the IC and
the coil as short as possible.

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.
