Article Summary

July 11, 2006 STMicroelectronics and Blaupunkt have come up with an interesting new solution for good old AM/FM car radio that makes a lot of sense. A newly developed dual-tuner receiver chipset uses sophisticated digital signal processing techniques to enable excellent reception quality while reducing interference even in presence of challenging signal conditions such as weak field and strong multipath (reflection from mountains and buildings). The advanced digital receiver integrates audio signal processing and Radio Data System (RDS) decoding, and hence delivers quality and system cost optimization suitable for high-end car radios. 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. Samples of the chipset are available now and volume production is scheduled for the second quarter of 2007.
