DALLAS, May 24 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the first device in the family of PurePath™ Wireless audio products for consumer, portable and high-end audio applications, such as wireless headphones and wireless speakers. The CC8520 is an audio transceiver featuring a 2.4-GHz system-on-chip that transmits uncompressed CD-quality wireless audio over a state-of-the-art RF (radio frequency) link with no unwanted noise or dropouts. The CC8520 simplifies implementation of wireless audio while reducing the customer's bill of materials (BOM) cost by 50 percent compared to competitive products. For more information or to order development kits, please see www.ti.com/cc8520-pr.

"TI has applied extensive design expertise in both digital audio and low-power RF, working closely with key customers, to deliver a turnkey wireless audio solution that many major audio customers are already designing into their new systems," said Laurent Giai-Miniet, general manager of TI's Low-Power RF business unit. "The CC8520 solution includes best-in-class hardware, software and development kits to streamline the process of eliminating cables in audio designs and to drive high-performance wireless digital audio into more consumer applications, such as headphones, headsets, speakers, subwoofers and home theater systems."
