Texas Instruments (News - Alert) (TI) has introduced the second device in the family of PurePath Wireless audio products for consumer, portable and high-end audio applications.

The uncompressed wireless audio is transmitted over a robust RF link by the 2.4 GHz CC8530 radio frequency (RF) system-on-chip. In addition, it also supports digital streaming for up to four audio channels.

Additionally, TI also introduced the CC85XXDK-HEADSET development kit and reference design as part of the PurePath Wireless audio family.

“PurePath Wireless audio represents TI's industry leading expertise in digital audio and wireless connectivity markets,” said Erling Simensen, product marketing manager for wireless audio at TI.

Simensen said that 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.

Some of the key features and benefits of CC8530 solution include multichannel audio streaming capability. Company officials said that it features four speakers receiving independent audio streams from wireless base station; and up to four headphones receiving either stereo A or stereo B audio from the same base station.

Additional features include RF protocol, microcontroller, audio codec setup support, application designs; free Configurator PC software tool for easy configuration. In addition, it comes with high quality-of-service for digital wireless audio transmission; and more.

CC85XXDK-HEADSET development kit features 22 hours on 465mAh battery; consists of all-TI components; cost-effective design for high-quality wireless headsets and headphones; fully programmable with PurePath Wireless Configurator PC tool. Company officials said that it includes TI’s BQ25015 power management device, the low-power TLV320AIC3204 audio codec and CC2590 range extender; and more.

“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, adding that thanks to PurePath Wireless technology, the company’s designs offer unwired multipoint audio streaming, and our audio systems can expand to up to four speakers and cover two stereo-audio listening zones.

The Company has also announced its new C2000 Concerto dual-core microcontroller (MCU) series.
