CEVA Speeds the Development of True Wireless Stereo Earbuds with Support of Bluetooth LE Audio

January 8 2020, 00:15
CEVA, the wireless connectivity specialist, announced that it has enhanced its offerings for developers of true wireless stereo (TWS) earbuds and other wireless audio devices with the general release of the RivieraWaves Bluetooth Low Energy and Dual Mode IPs with support for LE Audio, the next generation of Bluetooth audio. The CEVA solution introduces new features that enhance audio quality and link robustness as well as enabling new audio sharing use cases. 

LE Audio is one of the most important Bluetooth innovations in recent times, and CEVA’s unique portfolio of Bluetooth Dual Mode and Bluetooth Low Energy IPs, along with its DSPs, audio/voice software and sensor fusion technologies positions CEVA as an industry’s leading one-stop-shop provider for advanced wireless audio solutions.

“The Bluetooth community continues to drive the technology forward to meet evolving market needs and create new opportunities," says Mark Powell, CEO of Bluetooth SIG. “LE Audio is a prime example. Not only will it enhance the performance of existing Bluetooth audio products, it introduces Audio Sharing, a new audio use case poised to transform the way we experience audio and connect with the world around us.”

The audio quality improvements are courtesy of the new LC3 codec called LC3, or Low Complexity Communications Codec, which also enables lower power operation and so extending the battery life of TWS earbuds and other audio streaming devices. LC3 is already optimized for CEVA’s Audio DSPs.

“We congratulate the Bluetooth SIG on the introduction of LE Audio,” says Ange Aznar, Vice President and General Manager of the Wireless IoT Business Unit at CEVA. “We have a large customer base for both our Bluetooth Low Energy and Bluetooth Dual Mode IPs and we’re already seeing strong demand from customers for LE Audio to bring new wireless audio product offerings to the market.”

CEVA’s RivieraWaves Bluetooth IP platforms provide comprehensive solutions for both Bluetooth LE and Bluetooth dual mode connectivity. Each platform consists of a hardware baseband controller, plus a feature-rich software protocol stack. A flexible radio interface allows the platforms to be deployed with either RivieraWaves RF or various partners’ RF IP, enabling optimal selection of foundry and process node.

All the latest features of Bluetooth are supported, including Isochronous Channels for LE Audio, Direction Finding (AoA/AoD), Randomized Advertising Channel Indexing, Periodic Advertising Sync Transfer, GATT Caching and other enhancements. With more than 2 billion devices shipped to date and dozens of licensees, the RivieraWaves Bluetooth IP is widely deployed in consumer and IoT devices with many of the world’s leading semiconductors companies and OEMs, including smartphones, tablets, wireless speakers, wireless headsets and earbuds, hearing aids and other wearables.
