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

DALLAS , Jan. 6 /PRNewswire/ — At the 2010 International Consumer Electronics Show (CES) (East Tower, Suite 464), Texas Instruments (TI) (NYSE: TXN) will demonstrate 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.

Key features and benefits

  • High quality-of-service for digital wireless audio transmission
    • Lower latency than WLAN-based 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 16-bit, 44.1-KHz or 48-KHz audio without any compression.
    • Excellent coexistence with Bluetooth ®, WLAN and other 2.4-GHz devices.
  • Fast time-to-market and flexible, cost-effective solution
    • Single-chip IC with built-in 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 easy-to-use designer's tool.
  • Compatible with wide variety of TI audio codecs (TLV320AIC3101), digital-to-analog converters (PCM1774), analog-to-digital converters (PCM1870A) and digital audio amplifiers (TPA6140A2, TAS5708) using I2S and I2C interface support.

CC85xx family availability

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:

  • PC-based PurePath™ Wireless configuration tool.
  • CC8520DK audio development kit.
  • CC8520DK-HEADSET wireless headset reference design.
