TDA7338

TDA7338 STEREO DECODER INTEGRATED 19KHz SC NOTCH FILTER FOR PILOT CANCELLATION ON CHIP FILTER FOR PILOT DETECTOR AND PLL ADJUSTMENT FREE VOLTAGE CONTROLLED OSCILLATOR AUTOMATIC PILOT DEPENDENT MONO/ STEREO SWITCHING NOISE BLANKING WITH PROGRAMMABLE THRESHOLD HIGH CUT CONTROL AND STEREO BLEND INTEGRATED HIGH PASS FILTER FOR INTERFERENCE DETECTOR LEVEL INPUT FOR ADDITIONAL SPIKE DETECTION ON FIELDSTRENGHT SIGNAL VERY HIGH SUPPRESSION OF HARMONIC AND INTERFERENCE SIGNALS DESCRIPTION The TDA7338 is a new concept of monolithic integrated stereo decoder with noise blanking for FM car radio applications. With the used BICMOS technique, the 19KHz Notch Filter, the PLL Filter and Phase Filter is rePIN CONNECTION (Top view) SO20 DIP20 ORDERING NUMBER: TDA7338(DIP20) TDA7338D( SO20) alized on the chip with a Switched Capacitor concept. Avoiding the use of multipliers and non linear circuits a very high performance in terms of noise suppression and total harmonic distortion is reached.
