MUNICH, Germany Adressing the needs of high-end car radios, Bosch affiliate Blaupunkt GmbH has developed a highly integrated ASIC that replaces up to four separate electronic modules. In addition to conventional AM and FM reception, the chip supports all popular digital radio schemes.
In the first place, the car radio and navigation system manufacturer developed the chip for its captive market – with a sales volume of 1,4 billion Euros in 2005, this market could be big enough to justify such a design. Nevertheless, the chip also will be available to interested third parties, a company spokesman explained. Thus, the company wants to address the car radio vendors requirement for modules and chips that can be used worldwide. Dubbed ADR (Advanced Digital Receiver), the chip will be incorporated in new car radio designs beginning 2007.
The single chip design is based on the company's DDA technology (digital directional antenna) with two separate digital receivers. Additional circuitry includes an ARM processor core and and a DSP. With alogorithms developed by Blaupunkt, the chip supports Digital Audio Broadcast (DAB) as well as DRM (Digital Radio Mondiale) and the American standards HD-Radio and SDARS (Satellite Digital Audio Radio Service). Features include signal propagation time compensation for audio signals and car specific sound equalizing.
