2.4 GHz RF SoC FOR WIRELESS DIGITAL AUDIO STREAMING

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.
