Pin Definitions and Functions
Function
Phase detector output, PLL loop filter
Oscillator pin (456 kHz)
Ground
Reference current pin, external reference resistor
Positive supply voltage
Interference detector input, noise detector input
Timing capacitor for monoflop (gate time)
Low voltage applied turns off oscillator, phase detector, pilot detector, SNC
and changes the time constant for HCC, noise gate monoflop
Hold capacitor for noise detector average level
Low voltage applied mutes the stereo decoder output, noise level capacitor
Auxiliary input left, output amplifier left
Audio signal output left
Audio signal output right
Auxiliary input right, output amplifier right
HCC timing/hold capacitor, deemphasis right
HCC timing/hold capacitor, deemphasis left
Input for HCC voltage
Input for SNC voltage
Input for reference level control voltage (HCC and SNC)
Pilot indicator output, open collector, active low
Pilot detector output
Low voltage applied switches the stereodecoder to mono state
Input for MPX signal
