Pilot Q Detector Output

This pin is connected to the Pilot Q detector and

requires a 0.47

µF capacitor to ground to filter the

error line voltage at the PLL pilot tone detector. If the

value of this capacitor is made too large, the

decoder may be prevented from coming back into

stereo after a signal drop out has been experienced

in the field. The force to mono function is also

accomplished at this pin by pulling the dc voltage

level at the pin below 1.0 V.

Pilot Signal Input

A capacitor to ground forms a filter for the pilot input

signal. The recommended value of the capacitor is

0.22

µF. The dc level at Pin 11 is approximately

1.0 Vdc.

Oscillator Input

The oscillator pin requires a ceramic resonator and

parallel capacitor connected to ground. The

recommended source for the ceramic resonator is

Murata, part number CSA 3.60MGF108.

A 43 pF NPO capacitor is in parallel with the

resonator. The dc level at Pin 13 is approximately

1.1 Vdc.
