Integrated Circuit

Phase Lock Loop (PLL) FM Stereo Demod

Description:

The NTE1461 is a multiplex integrated circuit in a 16−Lead SIP type package designed for use in FM

car stereo applications. Due to its low distortion factor, this device can be used as a multiplex stereo

demodulator appropriate for car component stereo units.

Functions:

D Stereo Noise Control (SNC Pin):

Through controlling the quality of sound from stereo mode to monaural mode with the voltage ap-

plied to the control pin, the FM stereo noise in the weak electic field is reduced by this function.

D High−Cut Control Function (HCC Pin):

The FM noise in weak electric field is reduced through the attenuation of high frequency thereof.

Such attenuation can be changed smoothly from “Normal” to “High−Cut” by controlling the voltage

applied to the control pin. The volume of “High−Cut” can be selected by using a capacitor

installed at the outside of he unit.

D Stereo/Monaural Automatic Conversion:

This conversion operates in priority to the stereo noise control. Preference on the pilot input.

D Stoppage of VCO Oscillation:

When a voltage higher than 6V is applied on the HCC pin, the oscillation of VCO can be dis-

continued. An erroneous operation of stereo lamp does not happen even at this stage.

D With spearation control terminal
