TDA7519 Multichip module for car radio applications Features ● High-performance signal processor for car radio applications ● Adjustment-free stereo decoder ● FM noise blanker ● Programmable multipath detector ● 2 Stereo and 2 mono inputs with mixing capability ● Bass, treble and loudness controls ● 4 Independent speaker outputs ● High-performance fully digital RDS demodulator ● On-chip adjustment-free 57kHz 8th order bandpass filter ● ARI (SK indication) and RDS signal quality output ● LQFP44 Two devices are included: TDA7460N, and TDA7479. (please refer to the relevant datasheet for specifications) 2 Full I C-bus control Description The TDA7519 multichip module combines in a single compact (10x10mm) 44-pin package, the signal processing functionalities of a state-of-theart car radio, with a minimized number of required external components. TDA7460N is a digitally controlled stereo decoder and audioprocessor, featuring FM noise blanking and multipath detector; bass, treble, loudness controls with 2 stereo and 2 mono mixable inputs and four independent speaker outputs. TDA7479 is a fully digital RDS data decoder with an on-chip adjustment-free bandpass filter. Both chips are I2C bus controlled.
