The 2,4 GHz CC8530 radio frequency (RF) system-on-chip transmits uncompressed wireless audio over a robust RF link and supports digital streaming for up to four audio channels. TI also introduced the CC85XXDK-HEADSET development kit and reference design as part of the PurePath Wireless audio family. The design has a low total electronic bill-of-material cost and achieves a 22 hour life on a 465 mAh battery.
With the ability to stream two stereo streams from one audio source to several receivers, the CC8530 enables new use cases for wireless headsets and multichannel home audio applications, such as surround sound speaker systems with no need to pull wires across the house, and headphones that switch between two audio streams coming from one stereo system.
