TI to demonstrate uncompressed CD-quality wireless audio technology at CES

PurePath(TM) Wireless features robust, low-latency digital wireless audio transmission for consumer audio applications

(PresseBox) (Dallas, ) At the 2010 International Consumer Electronics Show (CES) (East Tower, Suite 464), Texas Instruments (TI) (NYSE:TXN) will demonstrate its new PurePath(TM) Wireless audio technology, delivering the industry's highest performance CDquality wireless audio solution. The CC85xx family takes advantage of TI's design expertise in both audio and lowpower RF products to provide a 2.4-GHz systemonchip that transmits uncompressed audio over a stateoftheart RF link with no unwanted noise or dropouts. These singlechip, integrated devices will lower total system cost in consumer, portable and professional audio applications, such as wireless headphones and wireless speakers.

Key features and benefits

- High qualityofservice for digital wireless audio transmission

- Lower latency than WLANbased solutions for better synchronization between audio and video.

- No unwanted noise (clicks or pops) and low MTBD (mean time between dropout) compared to existing solutions.

- None of the sound distortion typically found in competing proprietary systems using compression techniques.

- Supports 16bit, 44.1-KHz or 48-KHz audio without any compression.

- Excellent coexistence with Bluetooth®, WLAN and other 2.4-GHz devices.

- Fast timetomarket and flexible, costeffective solution

- Singlechip IC with builtin RF protocol and audio codec setup. No software development required.

- No microcontroller required. CC85xx can configure external audio codecs and control human interface.

- Application reference designs and easytouse designer's tool.

- Compatible with wide variety of TI audio codecs (TLV320AIC3101), digitaltoanalog converters (PCM1774), analogtodigital converters (PCM1870A) and digital audio amplifiers (TPA6140A2, TAS5708) using I2S and I2C interface support.

CC85xx family availability

The twochannel CC8520 will be sampling and in volume production in March 2010. Future devices in the family will include the CC8521 (two channels with USB), CC8530 (three channels) and CC8531 (three channels with USB).

The devices will be packaged in a ROHScompliant 6 mm x 6 mm QFN-40. TI will support these devices with comprehensive demonstration kits, reference designs and tools that provide all the hardware and software necessary to evaluate the CC85xx devices:

- PCbased PurePath(TM) Wireless configuration tool.

- CC8520DK audio development kit.

- CC8520DK-HEADSET wireless headset reference design.
