Notes
10
IF input
IF input via the phase shift circuit. The mute
circuit malfunctions and demodulation output
decreases if the voltage level at this pin
drops below 180 mV.
11
Vref

12
VCC
Supply voltage 7.5 to 14 V
13
IF buffer output
14
GND
FM detection circuit GND
15
Mute driver
Amount of mute attenuation depends on and
is controlled by the voltage at this pin.
16
S-meter output
PNP open collector output
17
SD sensitivity setting
Can be used for S-meter output
18
SD output
