Texas Instruments (TI) today announced the first device in its PurePathTM wireless audio portfolio for consumer, portable and high-end audio applications such as wireless headsets and wireless speakers. The CC8520 is an audio transceiver with a 2.4 GHz system-on-chip that delivers uncompressed CD-quality wireless audio over a state-of-the-art RF (radio frequency) link in a noise-free and voltage-dropped condition. Compared to competing products, the CC8520 not only reduces customer bill of materials (BOM) costs by 50%, but also simplifies the implementation of wireless audio.

Laurent Giai-Miniet, General Manager of TI's Low-Power RF Business Unit, noted: "TI has adopted a wide range of professional design techniques for digital audio and low-power RF, and has worked closely with key customers to deliver turnkey wireless audio solutions. Many major audio customers are now using it in new system designs. The CC8520 solution includes the industry's best hardware, software, and development kits to optimize processes, eliminate the need for cables in audio designs, and handle handsets. High-performance wireless digital audio with more consumer applications such as headsets, speakers, subwoofers, and home theater systems."
Key Features and Benefits • Complete integrated solution for RF protocol and audio codec setup support, application design and free PurePath Configurator PC software tools;
• No need to develop a microprocessor or software, it is a highly flexible and cost-effective solution that speeds time to market;
• Provides high quality service for digital wireless audio transmission:
o No annoying noise (噼噗 or hum) and high mean voltage drop time (MTBD) compared to existing solutions;
o Excellent coexistence with Bluetooth®, WLAN and other 2.4 GHz devices;
o Low latency for better synchronization between audio and video;
o Eliminates common sound distortion for competitive proprietary systems that use compression technology;
o Supports 16-bit 44.1 KHz or 48 KHz audio without any compression.
• Compatible with various TI audio codecs (TLV320AIC3101), digital to analog converters (PCM1754), analog to digital converters (TLV320ADC3001), and audio amplifiers (TPA6140A2 and TAS5713) that provide I2S and I2C interface support.
The dual channel CC8520 is available now and can be ordered through TI and its authorized distributors. The CC8520 is available in a ROHS-compliant 6 mm x 6 mm QFN-40 package. The series will also provide CC8521 (supports dual channel and USB), CC8530 (3 channels) and CC8531 (supports 3 channels and USB).
The comprehensive demonstration kit helps you get started right away, and it provides all the hardware and software necessary to evaluate the CC8520. The CC85XXDK Development Kit includes 2 PurePath Wireless Audio Evaluation Boards and 2 CC85XXEM RF Evaluation Boards.
