NTE7050

The NTE7050 from NTE Electronics is a Phase Lock Loop (PLL) stereo decoder integrated circuit, housed in a 16-Lead DIP package. This component is specifically designed for automotive radio applications.

Key electrical characteristics include a maximum supply voltage of 18V and an operating supply voltage range of 7V to 16V. The device operates within an ambient temperature range of -30°C to +80°C. It features a typical current consumption of 15mA (without LED driver) and a power dissipation of 125mW. The total power dissipation is rated at 1.6W at +25°C.

The NTE7050 incorporates features such as a Voltage-Controlled Oscillator, Pilot Presence Detector, and an Automatic Mono/Stereo Switch. It also includes a Matrix, amplifiers for left and right output signals, output buffers with 10dB gain, and a mute circuit. A source selector for radio or cassette is also integrated, along with an input amplifier whose gain can be adjusted externally. The device includes a pilot cancelling circuit for enhanced pilot signal suppression and a Signal Dependent Stereo (SDS) circuit for smooth stereo to mono transitions.

The stereo decoder is compensated for a typical IF filter with a roll-off frequency of 50kHz. The typical gain of the input amplifier is 20dB.
