In a standards-driven world, it’s a pretty big deal when a product is first to achieve a standard body’s qualification. CEVA has pulled off that trick with respect to its RivieraWaves Bluetooth Low Energy (BLE) 5.2 platform, which has achieved Bluetooth SIG qualification. As the first IP company to receive Bluetooth LE 5.2 qualification, CEVA enables its licensees to reduce their product development risk and so benefit with expedited time-to-market and end-product qualification process.
Version 5.2 of the BLE standard introduces Isochronous Channels, an addition meant to address the growing demand for higher performance and lower power wireless earbuds and other audio peripherals including headsets, smart speakers, and sound bars.
Additionally, Isochronous Channels (ISO) over BLE is the foundation for BLE Audio. Thanks to ISO, which is supported in BLE 5.2, several low-latency and synchronized channels can be setup to stream audio over BLE to several sinks, such as a pair of wireless earbuds. The audio experience is extended thanks to significantly reduced power consumption compared to Classic Audio, and improved audio quality thanks to the new LC3 codec, complemented by the possibility to stream audio to an unlimited number of devices. The latter, called Audio Sharing, allows people in a public area to grab the audio stream from nearby TVs or monitors.
CEVA’s RivieraWaves Bluetooth IP platforms provide comprehensive solutions for both BLE 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 with various partners’ RF IP, enabling optimal selection of foundry and process node. All the latest features of Bluetooth are supported, including Isochronous Channels for BLE Audio, Direction Finding (AoA/AoD), Randomized Advertising Channel Indexing, Periodic Advertising Sync Transfer, GATT Caching, and other enhancements.
