IC MSP 34X0G is a single chip that can process voice signals to all TV standard International, and very good for the digital NICAM stereo. In the IC has several advantages, namely: Communication using the I2C bus control Selection of a voice signal automatically (mono / stereo / bilingual) Loudspeaker / headphones are equipped with volume control, bass, treble, loudness and balance Loudspeaker outputs are equipped with MDB (Micronas Dynamic Bass) AVC: Automatic Volume Correction Equipped with Sub woofer output Have facilities 5-Band graphic equalizer for loudspeaker Equipped spatial effect for loudspeaker Equipped with a matrix of voters in / out Has a SCART 4 stereo inputs, one mono input and 2 stereo SCART output Block diagram of circuit in the IC MSP34X0G

General Description: The TDA7500 is an integrated circuit implementing a fully digital, integrated and advanced solution to perform the signal processing in front of the power amplifier and behind the AM/FM tuner or any other audio sources. The chip integrates two 43 MIPs DSP cores: one for stereo decoding noise blanking, weak signal processing and multipach detection and one for sound processing. Block Diagram:
