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

Idrive High
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
390
capacitor controls the PLL corner frequency

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

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
