NTE1631
Integrated Circuit
FM Stereo Multiplexer w/ Soft Muting
Features:
D Compact Package
D Channel separation as well as high−frequency cutting can be controlled by means of control
inputs
D A control input us used to force monaural operation and inhibit oscillations when the applied
voltage is low (V_CC = 0V)
D For a fixed−input waveform phase shift (sub−signal reduced 20%) channel seperation is set to
maximum using an internal resistance.
D Setting the AM switching input to high forces monaural operation, inhibits oscillations, and can-
cels the high−cut function.
D Setting the forced monaural input to high forces monaural operation and inhibits oscillations
D Precautions have been taken to eliminate abnormal operation as well as pop noise occuring
with power supply and mode switching functions
D Indepent high−impedance demodulating and PLL inputs have been provided to enable either
directly connected or independent operation
D Wide dynamic range
D +3dB input/output gain
D Low distortion (0.1%)
D Wide supply voltage range (6V to 12V)
Applications:
D Car Stereo
D Music Center
D Stereo adio Cassette Tape Recorder
D Other Stereo Equipment
Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)
