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.

Features:

• Low Distortion Factor: 0.05 Typ, 300mV Input Mono

• The Ripple of Power Source can Effectively be Rejected

• Wide Supply Voltage Range: VCC = 6.5V to 14V

Functions:

• Stereo Noise Control (SNC Pin):

Through controlling the quality of sound from stereo mode to monaural mode with the voltage applied to the control pin, the FM stereo noise in the weak electic field is reduced by this function.

• 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.

• Stereo/Monaural Automatic Conversion:

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

• Stoppage of VCO Oscillation:

When a voltage higher than 6V is applied on the HCC pin, the oscillation of VCO can be discontinued. An erroneous operation of stereo lamp does not happen even at this stage.

• With spearation control terminal
