TI sets new tune for wireless digital audio streaming with industry's first complete wireless headset reference design

DALLAS, USA: Texas Instruments Inc. (TI) has introduced the second device in the family of PurePath Wireless audio products for consumer, portable and high-end audio applications. The 2.4 GHz CC8530 radio frequency (RF) system-on-chip transmits uncompressed wireless audio over a robust RF link, and supports digital streaming for up to four audio channels.

TI also introduced the CC85XXDK-HEADSET development kit and reference design as part of the PurePath Wireless audio family. As the market's most cost-effective offering for high-quality headsets and headphones, the design has a total electronic bill-of-material cost of less than USD $5 in high-volume production, and achieves a 22-hour life on a 465 mAh battery – a 100 percent increase as compared to currently available headsets.

"PurePath Wireless audio represents TI's industry leading expertise in digital audio and wireless connectivity markets," said Erling Simensen, product marketing manager, wireless audio, TI. "We've done all back-end work with the new wireless headset reference design, so engineers can build a prototype in less than one day. With the ability to stream two stereo streams from one audio source to several receivers, the CC8530 will enable exciting new use cases for wireless headsets and multichannel home audio applications, such as surround sound speaker systems with no need to pull wires across the house, and headphones that easily switch between two audio streams coming from one stereo system."

"TI's PurePath Wireless technology enables us to design cutting-edge wireless audio products," said Robert Wills, president, InterSource OEM Inc. / Claridy Amps, a design house specializing in audio products. "Thanks to PurePath Wireless technology, our high-quality designs offer unwired multipoint audio streaming, and our audio systems can expand to up to four speakers and cover two stereo-audio listening zones. Products such as Sound of Lights wireless speakers are sparking tremendous interest with great customer feedback, and we look forward to continued work with the TI team."
