Frontier Silicon is launching its Chorus 2i baseband receiver SoC, bringing over 10,000 Internet radio stations and network audio streaming capability to sub-$99 Wi-Fi radios. The device is said to be the first multimode IC to combine analog and digital broadcast reception with complete IP connectivity, enabling manufacturers to easily design and produce radios capable of receiving Internet, DAB and FM radio stations, with the addition of network audio streaming through existing home Wi-Fi and Internet connections.

The chip, along with a complete software development kit, module and reference platforms, is sampling to customers this month, with radios expected in the shops by summer.

"With audio content increasingly becoming available on-line, audio receivers must embrace Wi-Fi connectivity to avoid obsolescence within a few years," said Steve Evans, Frontier Silicon's VP for digital audio. "While the majority of audio products today rely on broadcast technology, we are now in the transition decade where consumers will increasingly demand access to digital content from the Internet. This chip will accelerate the introduction of the new generation of home audio systems by bringing Internet radio and streaming into mass market radios and audio systems."

Measuring a compact 13-by-13mm, the advanced Chorus 2i SoC has a flexible DSP architecture that ensures the chip has sufficient capacity to run all the streaming protocols and audio decoders necessary for a Wi-Fi radio application, along with spare resources to provide DAB and FM functionality. Unique to Chorus 2i is the integration of peripheral features on-chip, such as the USB 2.0 OTG interface for music download/playback and software upgrade, support for TFT and LCD displays, and ATA/ATAPI interface for hard-disc storage, NAND Flash, memory stick and SD interfaces.

Chorus 2i streams radio stations and music files in a variety of formats and protocols including MP3, WMA, Real Audio, AU, WAV and AIFF. The chip integrates an intuitive user interface which enables setup, search and browse of over 10,000 Internet radio stations plus a wide selection of pod casts with only a few key presses. The radio stations and pod casts are accessed through the vTuner Internet portal, which manages all the stations to ensure the quality and reliability of the available content.

Unlike other broadcasting standards which vary from country to country, Internet radio products are not constrained by geographic location.
