Loop Filter

A capacitor which forms the loop filter is connected

from Pin 14 to ground. The recommended value is

47

µF in series with 47 Ω. This capacitor should be of

good construction quality so it will have a very low

specification for leakage current in order to prevent

stereo distortion. The 47

Ω resistor in series with the

capacitor controls the PLL corner frequency

response, keeping the response shape critically

damped and not peaked up. The dc level at Pin 14 is

approximately 0.6 Vdc in the locked condition.

Left Channel Audio Output

This is the left channel audio output pin from which

the IC can provide 1.3

µApp drive current for each

percent of mono modulation. A resistor to ground

sets the level of the audio output.

For example,

100% (mono mod) x 1.3

µApp (IC

drive per % mod) = 130

µApp flowing through the

load resistor. (For a 2.2 k load, 286 mVpp is then

the output signal voltage.) When dealing with

stereo signals, multiply the mod level by 2; i.e.

50%

(left only mod) x 2 (stereo factor) x 1.3

µApp (IC

drive per % mod) = 130

µApp flowing through the

load resistor.

Right Channel Audio Output

This is the right channel audio output pin. A resistor

to ground sets the level of the audio output. See the

explanation under the Left Channel Audio Output
