Pin Function

Internal Circuit

Internal filters (i.e. sound carrier BPF and sound

carrier trap) are tuned using the capacitor

FILTER CONTROL connected to pin 25.

25

CAPACITOR

A value between 0.47 µF and 1 µF is considered

desirable taking video S/N, and AM and PM noise

into consideration.

NC

Not connected

Pin 27 is the SIF PLL filter pin.

Normally use the following values.

R: 3 kΩ

C1: 0.01 µF

C2: 1000 pF

27

SIF PLL FILTER

A large R value (6 kΩ or lower) results in high-pass

FM detection output noise. A smaller R value

results in low-pass noise.
