TI unveils industry’s first complete wireless headset reference design
TI also introduced the CC85XXDK-HEADSET development kit and reference design as part of the PurePath Wireless audio family. As the market’s most cost-effective offering for high-quality headsets and headphones, the design has a total electronic bill-of-material cost of less than USD $5 in high-volume production, and achieves a 22-hour life on a 465 mAh battery – a 100 percent increase as compared to currently available headsets.
“PurePath Wireless audio represents TI’s industry leading expertise in digital audio and wireless connectivity markets,” said Erling Simensen, product marketing manager, wireless audio, TI. “We’ve done all back-end work with the new wireless headset reference design, so engineers can build a prototype in less than one day. With the ability to stream two stereo streams from one audio source to several receivers, the CC8530 will enable exciting 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 easily switch between two audio streams coming from one stereo system.”
Multichannel audio streaming capability of the CC8530 includes the ability to have four speakers receiving independent audio streams from wireless base station or up to four headphones receiving either stereo A or stereo B audio from the same base station. The CC8530 offers a complete solution with RF protocol, microcontroller, audio codec setup support, and application designs. Further no software development is required with the free Configurator PC software tool for easy configuration.
Further the SoC offers a high quality-of-service for digital wireless audio transmission, including:
- Excellent coexistence with Bluetooth® technology, WLAN and other 2.4-GHz devices;
- Distributed audio clock for synchronized wireless speakers;
- Low latency for better synchronization between audio and video;
- No unwanted noise (clicks or pops);
- High mean time between dropout (MTBD) as compared to existing solutions;
- No sound distortion typically found in competing proprietary systems; and
- Support for 16-bit, 44.1-KHz or 48-KHz audio without any compression.
Key features and benefits of the CC85XXDK-HEADSET development kit are:
- 22 hours on 465 mAh battery: 100% longer battery life compared to today’s standard headsets
- Consists of all-TI components
- Cost-effective design for high-quality wireless headsets and headphones
- Enables easy testing of complete headphone and headset functionality
- Fully programmable with PurePath Wireless Configurator PC tool.
- Includes TI’s BQ25015 power management device, the low-power TLV320AIC3204 audio codec and CC2590 range extender
The multi-channel CC8530 is available today from TI and through authorized TI distributors. The solution is packaged in a ROHS-compliant, 6 mm x 6 mm QFN-40. Future devices in the family will include the CC8521 (two channels with USB) and CC8531 (four channels with USB).
