TDA7338

INTEGRATED 19KHz SC NOTCH FILTERFOR 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

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 realized 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.
