描述 Description

Description:
The NTE7050 is a Phase Lock Loop (PLL) stereo decoder with cassette head amplifiers in a 16–Lead DIP type package designed especially for car radios. This device has SDS circuitry where fluctuating signal strength can cause demodulation noise and distortion. The stereo decoder is compensated for a typical IF filter with a roll–off frequency of 50kHz (2dB down at 38kHz).Features:
• A Voltage–Controlled Oscillator
• A Pilot Presence Detector and an Automatic Mono/Stereo Switch
• A Matrix and Two Amplifiers for the Left and Right Output Signal
• Two Output Buffers with 10dB Gain and Low Output Impedance
• Mute Circuit
• A Source Selector for Radio or Cassette
• An Input Amplifier of which the Gain can be Adjusted by means of an External Input Resistor
• A Pilot Cancelling Circuit for an Extra Suppression of the Pilot Signal of 15dB
• An Signal Dependent Stereo (SDS) Circuit for a Smooth Change Over from Stereo to Mono at Weak Tuner Input Signals
