A dual-band WiFi audio chip, claimed to be the industry’s first, has been released by Broadcom. The BCM43907 SoC, which expands the company’s Wireless Internet Connectivity for Embedded Devices (WICED) portfolio, delivers HD audio streaming over a WiFi network to wireless audio devices.

The required functionality is integrated within a single chip, reducing cost for OEMs. Interference is minimised by the SoC’s dual-band WiFi, delivering higher quality sound to wireless streaming devices such as portable speakers, 5.1 multi-speaker systems, sound bars and media players.

Featuring advanced RF and timing synchronisation, the BCM43907 enables the same content to be streamed over multiple speakers in different rooms in the home with no echo or lag time.

Expanding opportunities for developers and OEMs designing products that stream audio content from the home network or mobile devices, the chip offers pre-integrated Apple Airplay support with direct access to Broadcom's WICED Audio software development kit.

"The significant improvement in sound quality of HD audio streaming over WiFi versus proprietary short range technologies is creating opportunities for a wide variety of wireless streaming devices," said Brian Bedrosian, Senior Director, Product Marketing, Wireless Connectivity Combos, Broadcom. "Broadcom's standards-based, fully integrated WICED Audio SoC offers companies of all sizes a platform to design both high-end and cost-effective WiFi audio products."
