Ceva-Waves Links is a growing family of multi-standard wireless platforms. By optimizing connectivity support for various combinations of Wi-Fi, Bluetooth, 802.15.4, and ultra-wideband (UWB), the Ceva-Waves Links family provides preconfigured, optimized solutions for SoCs requiring multiple connectivity standards. All Ceva-Waves Links configurations are based on field-proven Ceva-Waves hardware IP and software stacks. Unique Ceva coexistence algorithms ensure efficient and interference-free operation of multiple connections while sharing one radio.
The Ceva-Waves Links family offers combinations of Ceva-Waves Wi-Fi, Ceva-Waves Bluetooth, 802.15.4 (supporting protocols such as Thread, Matter and Zigbee), and Ceva-Waves UWB hardware IP, integrated with Ceva or third-party radios and CPU- and OS-agnostic software stacks. New platforms will be introduced to address market trends or customers’ demands.
Links100
The Ceva-Waves Links100 is a low-power multi-protocol wireless connectivity IoT platform combining a cost-optimized Wi-Fi 6 1×1 40 MHz solution, a Bluetooth 5.4 dual-mode solution supporting LE and Classic Audio and numerous profiles, and an 802.15.4 solution for Zigbee, Thread and Matter compliance. These modules are pre-integrated with a single low-power 2.4 GHz radio implemented in TSMC 22 nm and their operation is orchestrated through smart coexistence mechanisms.
Links200
The Ceva-Waves Links200 is a fully integrated multi-protocol wireless platform in TSMC 12nm FFC+ supporting Bluetooth High Data Throughput and IEEE 802.15.4 for Zigbee, Thread and Matter compliance. It pre-integrates all the necessary hardware, software and radio components for a cost effective, low power and high-performance solution to enable the development of advanced smart edge AI SoC in an easy and fast time to market manner. Compliant with Bluetooth 6.0, Links200 supports a comprehensive feature set including Audio streaming (Classic Audio, LE Audio, Auracast Broadcast Audio) with High Data Throughput mode for next generation lossless multi-channel LE Audio streaming, Localization including AoA/AoD for Direction Finding and Channel Sounding for accurate and secure ranging, Low latency mode for gaming supporting up to 8KHz refresh rate.
Implementing several connectivity standards in one SoC is a frequent requirement, but it has the potential to become far more complex than just the sum of the parts. Not only does the design require use-case-optimized MAC and PHY hardware IP and comprehensive protocol software for each mode, but it is necessary to efficiently interface each PHY to co-located radios or a shared radio. And operation of all the hardware must be orchestrated to avoid peak power issues, contention for the radio, or mutual interference between modes. Ceva-Waves Links solves all these problems by providing preconfigured, integrated, and optimized instances of MAC and PHY IP and software from the field-proven Ceva-Waves platform family. Members of the family span the performance range from energy-efficient IoT connectivity solutions to complex high-performance connectivity hubs. The IP designs provide hardware offload for key computational tasks including security, encryption, and difficult MAC functions. This not only speeds implementation of each individual module but avoids the potentially treacherous problem of integrating the modules and understanding their interactions. Thus, the Ceva-Waves Links platforms can provide very substantial reductions in design time and risk for multi-protocol SoCs, while providing state of the art performance for a broad range of applications including TWS earbuds, XR headsets, smart speakers, hearing aids, home audio, gaming, smart home, medical, automotive, smart watches and other consumer, wearable and Smart Edge AI IoT devices.
