CC8520RHAT Low Power RF
General Description:
The PurePath™ Wireless platform is a cost-effective and low-power solution optimized for wireless transmission of high-quality digital audio. The CC8520RHAT includes a robust built-in wireless audio transmission protocol and can control selected external audio devices. Utilizing numerous coexistence mechanisms allows the CC8520RHAT to avoid interfering with, or being interfered by other 2.4 GHz radio systems. The CC8520RHAT, which supports 2 audio channels, is the first device in the PurePath™ Wireless platform. The CC8520RHAT 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 CC8520RHAT interfaces easily with other TI audio ICs and DSPs (using I2S and DSP/TDM interfaces).
