CC85xx Family User Guide

By employing proprietary technology, referred to as PurePath Wireless, the CC85xx device family provides
robust, high-quality, short-range 2.4 GHz wireless digital audio streaming in low-cost single chip solutions.?
Two or more devices form a PurePath Wireless audio network. Great care has been taken to ensure that this
audio network provides gap-less and robust audio streaming in varied environments and that it can coexist
amicably with existing wireless technologies in the crowded 2.4 GHz ISM band.
Most applications can be implemented without any software development and only require the CC85xx to be
connected to an external audio source or sink (such as an audio codec, S/PDIF interface or class-D
amplifier) and a few push buttons, switches or LED? for human interaction. Advanced applications can
interface a host processor or DSP directly to the CC85xx and directly stream audio and control most aspects
of device and audio network operation.
The PurePath Wireless Configurator, a PC-based configuration tool, is used to set up the desired
functionality and parameters of the target system and then produces firmware images that subsequently
must be programmed into the embedded flash memory of each CC85xx.
All devices in the CC85xx family interface seamlessly with the CC2590 RF range extender device to allow for
even wider RF coverage and improved robustness in difficult environments.
