Overview
TDA7405 EQUALIZER CARRADIO SIGNAL PROCESSOR s s s s s s s s s s s s 3 STEREO INPUTS 3 MONO INPUTS DYNAMIC-COMPRESSION-STAGE FOR CD BASS, TREBLE AND LOUDNESS CONTROL EQ-FILTERS FOR SEPARATE FRONT/REAREQUALIZATION VOICE-BAND-FILTER FOR MIXING-CHANNEL DIRECT MUTE AND SOFTMUTE INTERNAL BEEP FOUR INDEPENDENT SPEAKER-OUTPUTS INDEPENDENT SECOND SOURCE-SELECTOR FULL MIXING CAPABILITY PAUSE DETECTOR TQFP44 ORDERING NUMBER: TDA7405 Digital control: 2 s I C-BUS INTERFACE DESCRIPTION Stereodecoder s RDS MUTE s NO EXTERNAL ADJUSTMENTS s AM/FM NOISEBLANKER WITH SEVERAL TRIGGER CONTROLS s PROGRAMMABLE MULTIPATH DETECTOR s QUALITY DETECTOR OUTPUT BLOCK DIAGRAM The device includes a high performance audioprocessor and a stereodecoder-noiseblanker combination with the whole low frequency signal processing necessary for state-of-the-art as well as future carradios.
The digital control allows a programming in a wide range of all the filter characteristics.
Also the stereodecoder part offers several possibilities of programming especially for the adaptation to different IF-devices.
