A two chip Digital Car Radio is presented which utilizes embedded digital signal processing from the IF input to the audio output. The first chip realizes an integrated AM/FM tuner, the second chip comprises an IF SigmaDelta converter with embedded 100 MIPS DSPs and multiple audio SigmaDelta converters. Compared with conventional solutions, the component count, trimming points and assembly time are improved and the board area is reduced by more than 50 %.
