Audio has been wireless from the beginning of radio, but has also from that time suffered from the inevitable quality loss of compression. CD-quality has been the holy grail of audio that is transmitted without wires. On January 6, 2010, Texas Instruments demonstrated its new PurePath Wireless audio technology, delivering the industry's highest performance CD-quality wireless audio solution.
The CC85xx family takes advantage of TI's design expertise in both audio and low-power RF products to provide a 2.4-GHz system-on-chip that transmits uncompressed audio over a state-of-the-art RF link with no unwanted noise or dropouts. These single-chip, integrated devices will lower total system cost in consumer, portable and professional audio applications, such as wireless headphones and wireless speakers.
The two-channel 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 ROHS-compliant 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.
