Features, Applications

AUDIOPROCESSOR: MUTE, SOFT MUTE AND ZERO CROSSING MUTE ONE DIFFERENTIAL, TWO STEREO AND TWO MONO INPUTS DIFFERENTIAL PHONE INPUT VOLUME, BASS, TREBLE AND LOUDNESS CONTROL FOUR SPEAKER ATTENUATORS WITH INDEPENDENT ATTENUATION CONTROL STEREODECODER: ADJUSTMENT FREE INTEGRATED 456KHz VCO HIGH CUT CONTROL STEREO BLEND NOISE BLANKER: INTEGRATED HIGH-PASS FILTER NOISE RECTIFIER OUTPUT FOR QUALITY DETECTION PROGRAMMABLE TRIGGER THRESHOLD PAUSE DETECTOR: PROGRAMMABLE THRESHOLD ALLFUNCTIONS PROGRAMMABLEVIA I2C BUS DESCRIPTION The TDA7340 I2C bus controlled audio signal processor contains all signal processing blocks of a high performance car radio, including audioprocessor, stereodecoder, noise blanker, pause

detector and different mute functions. The use of BICMOS technology allows the implementation of several filter functions with switched capacitor techniques like fully integrated, adjustment free PLL Loop filter, pilot detector with integrator and two 19KHz notch filters. This minimizes the number of external components. Due to a highly linear signal processing, using CMOS-switching techniques instead of standard bipolar multipliers, very low distortion and very low noise are obtained also in the stereodecoder part. The audioprocessor contains several new features like softmute, zero-crossing mute and pause detector. Very low Dc stepping is obtained by use of a BICMOS technology.
