Integrated Circuit
AM Tuner for Car Radio
Description:
The NTE1533 is developed for Tuning AM on a Car Radio. It uses low voltage oscillation to achieve
varactor diode tuning instead of variable inductance tuning.
Functions:
D An RF Amplifier
D A Mixer
D An Oscillator with Automatic Level Control (ALC)
D An IF Amplifier
D A Detector
D Normal AGC
D Wide Band AGC on an RF Amplifier
Features:
D Double Balanced Mixer: Recovers IF and Spurious Interference.
D Normal AGC: Less Influence of Detector Output against Varying Input.
D RF Wide Band AFC: Low Operating Level (300mV_RMS) Recovers Intermodulation Distortion,
Large Input Characteristic at Tuning Case of Varactor Diodes.
D AGC Driving Output to FET: Applies AGC to the Input FET at Varactor Diode Tuning.
D Automatic Level Control at Oscillator: Recovers a Tracking Error because an Oscillation Out-
put is Stabilized at Low Voltage Level (350mV_RMS) for Varactor Diode Tuning.
D Reference Voltage Output: 5.6V Reference Voltage for Other Uses.
D Compensation for V_CC error: Lower gain error and distortion over 7.5V to 16.0V.
D Lower Ripple Voltage: Less Modulation of Carrier by Supply Voltage Ripples.
D Low Pop Noise: Of Time Constant of AGC at V_CC On and Mode Switch On.
Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)
