Data Sheet

NTE1631
Integrated Circuit
FM Stereo Multiplexer w/ Soft Muting

Features:
Compact Package
Channel separation as well as high-frequency cutting can be controlled by means of control
inputs
A control input us used to force monaural operation and inhibit oscillations when the applied
voltage is low (VCC = 0V)
For a fixed-input waveform phase shift (sub-signal reduced 20%) channel seperation is set to
maximum using an internal resistance.
Setting the AM switching input to high forces monaural operation, inhibits oscillations, and cancels
the high-cut function.
Setting the forced monaural input to high forces monaural operation and inhibits oscillations
Precautions have been taken to eliminate abnormal operation as well as pop noise occuring
with power supply and mode switching functions
Independent high-impedance demodulating and PLL inputs have been provided to enable either
directly connected or independent operation
Wide dynamic range
+3dB input/output gain
Low distortion (0.1%)
Wide supply voltage range (6V to 12V)

Applications:
Car Stereo
Music Center
Stereo Audio Cassette Tape Recorder
Other Stereo Equipment
