The CC85XX Headset board reference design contains production material i.e., schematics, layout files, gerbers and BOM for the boards used in the CC85XXDK-HEADSET Development Kit. The design files are supplied as Gerbers, PDF-files and in Cadstar format. The reference design demonstrates good design techniques for RF and Audio layout and decoupling. For optimum RF and audio performance, the design should be copied as accurately as possible.
Applications supported with the design:
- Wireless audioo cable replacement
- Wireless headphones
- Wireless headset
- Wireles audio transmitter / base station
