STMicroelectronics' In-Car Advanced Digital Dual-Tuner System Improves Radio Reception in Critical Signal Conditions

STMicroelectronics announced that the company is sampling a new digital AM/FM radio receiver chipset for use in automotive applications.

Jointly developed by ST and Bosch’s subsidiary Blaupunkt, this advanced digital receiver integrates audio signal processing and Radio Data System (RDS) decoding, thus satisfying the demanding needs of today’s mid- and high-end car radios for world-class quality, high performance, and system cost optimization.

The new chipset includes two TDA7528 Radio Frequency (RF) front-end ICs and one STA3005 Digital Signal Processor (DSP) back-end IC. The solution tunes to all current analog radio services worldwide (AM, FM and US Weather band) as well as to the recently introduced digital broadcasts (Digital Audio Broadcasting, Digital Radio Mondiale, HD radio), providing suitable interfaces to external decoders.
