Broadcom's BCM43907 SoC reduces cost for original equipment manufacturers (OEMs) by integrating all needed functionality onto a single device. As the first audio SoC to implement dual-band Wi-Fi, Broadcom's BCM43907 reduces interference and delivers a cleaner overall sound to wireless streaming devices such as portable speakers, 5.1 multi-speaker systems, sound bars and media players. Devices with dual-band Wi-Fi experience fewer interruptions and benefit from a significant network performance boost by operating on two bands.

In addition, advanced radio frequency (RF) and timing synchronization enables the same content to be streamed over multiple speakers in different rooms in the home with no echo or lag time. This allows consumers to stream a variety of content to different speakers from the same device.

A consumer for example can use Bluetooth to listen to a radio station from their smartphone in one room of the home while simultaneously streaming music to a portable speaker in another room, all using the same device and Wi-Fi network.

"The significant improvement in sound quality of HD audio streaming over W-Fi versus proprietary short range technologies is creating opportunities for a wide variety of new wireless streaming devices," said Brian Bedrosian, Broadcom Senior Director, Product Marketing, Wireless Connectivity Combos.

"Broadcom's standards-based, fully integrated WICED Audio SoC offers companies of all sizes the ideal platform to design both high-end and cost-effective Wi-Fi audio products."

The Broadcom BCM43907 offers pre-integrated Apple Airplay support with direct access to Broadcom's WICED Audio software development kit (SDK), expanding opportunities for developers and OEMs designing products that stream audio content from the home network or mobile devices.
