Platform designed to provide improved security, less interference and better power consumption for wireless audio

CEVA’s RivieraWaves Bluetooth Dual Mode 5.3 Platform has achieved Bluetooth SIG Qualification, along with its GAF (Generic Audio Framework) and LC3 codec. As the first IP company to receive Bluetooth Dual Mode 5.3 qualification, CEVA brings the latest improvements in Bluetooth connectivity and LE Audio to its vast customer base, who are estimated to have shipped 1 billion CEVA-powered Bluetooth devices in 2021.

Bluetooth Dual Mode 5.3 introduces a number of key enhancements over its predecessor, including improved HCI Encryption Key Size Control to reinforce security, LE Channel Classification to improve robustness against interference and a range of other features to improve the user experience and power consumption particularly for LE Audio applications. With regards to LE Audio, the qualification of CEVA’s GAF and LC3 codec implementations serve to further reduce development risk and expedite time-to-market for semiconductors and OEMs targeting the new wireless audio use cases enabled by this technology, including longer listening times, shared audio and better hearing.

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, GAF, Direction Finding (AoA/AoD), LE Channel Classification and other enhancements.

With more than 3 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.
