Internal Equivalent Circuit

Description/External Circuit Requirements

Stereo Threshold Adjustment Pin

The function of this circuit is to provide the freedom

to achieve a desired value of incoming IF signal level

which will cause full stereo operation of the decoder.

The level can be determined by the value of R1, a

resistor from Pin 1 that can be connected to either

or to ground. This resistor may also be omitted

in some designs (Pin 1 left open). The approximate

dc level with the pin left open is 0.6 Vdc.

2.4 k

AGC

AGC Filter Bypass Capacitor

cap

An electrolytic capacitor is used as a bypass filter

and it sets the time constant for the AGC circuit

action. The recommended capacitor value is 10 µF

from Pin 2 to ground. The dc level at this pin varies

as shown in the curve in Figure 13, AGC Voltage

versus Input Level.

FBcap

IF Amplifier Feedback Capacitor

A capacitor which is specified to have a low ESR

at 450 kHz is normally used at Pin 3. The value

recommended for this capacitor is 0.47 µF from

Pin 3 to ground. This component forms a low pass

filter which has a corner frequency around 30 kHz.
