2.4 GHz RF SoC FOR WIRELESS DIGITAL AUDIO STREAMING CC8520 & CC8530 - PurePath™ Wireless
The PurePath™ Wireless platform is a cost-effective and low-power solution optimized for wireless transmission of high-quality digital audio.
The CC85xx includes a robust built-in wireless audio transmission protocol and can control selected external audio devices. Utilizing numerous coexistence mechanisms allows the CC85xx to avoid interfering with， or being interfered by other 2.4 GHz radio systems.
The CC85xx operates autonomously， and can be used with or without an external MCU. An external host processor can be connected through SPI and control some aspects of its operation. The CC85xx interfaces easily with other TI audio ICs and DSPs （using I2S and DSP/TDM interfaces）。 More details can be found in the CC85xx Family User Guide ［2］。
CC8520 & CC8530主要特性：
应用：
Wireless high-quality digital audio
Wireless point-to-point audio link
Wireless headphones
Wireless loudspeakers
Wireless 2.1 speaker systems
CC8520 supports up to 2 channels
CC8530 supports up to 4 channels
内置音频协议：
CD-quality uncompressed audio
Excellent robustness and co-existence through multiple techniques
Adaptive Frequency Hopping
Forward Error Correction
Buffering and Retransmission
Error Concealment
Optional high quality audio compression
No software development needed when used in autonomous mode
外接系统：
Can be used autonomously， or can be controlled by an external host MCU for greatest flexibility
Seamless connection and control of selected TI audio codecs， DACs/ADCs and digital audio amplifiers using I2S and I2C
