MIPI A-PHY becomes a standard automotive SerDes tech to reach mass production
Press Release, 24 September 2025
The MIPI Alliance has announced that its A-PHY specification has officially become the first automotive-grade SerDes (Serializer/Deserializer) standard to enter mass production. This milestone follows the deployment of an A-PHY‐based chipset by global automaker Lynk & Co in its 06 Relive SUV, produced by Geely Auto Group. This marks a significant step in automotive connectivity, as MIPI A-PHY promises robust, long-reach links (up to about 15 meters) primarily for in-vehicle high-speed image sensors and display connectivity tools central to advanced driver assistance, autonomous driving, and smart cockpit designs.
Other chipmakers are also gaining traction with A-PHY: Valens Semiconductor has secured upcoming design wins with European automakers, and Mobileye has picked up A-PHY-compliant chipsets for its sensor-to-compute systems used in autonomous vehicle project. As a standardized open physical layer, A-PHY supports multiple upper layer protocols, integrates functional safety and security by design, and has been adopted as IEEE 2977-2021. For OEMs, this means reduced reliance on proprietary SerDes solutions, greater compatibility across the supply chain, and potentially lower costs and faster innovation cycles.
With more than 50 companies now building or planning products around A-PHY, the ecosystem is expanding rapidly. The MIPI Alliance is also setting up a compliance program and interoperability test events to ensure parts actually work together properly in real automotive settings. Overall, entering mass production gives A-PHY a premier status, as it shifts from spec and design wins into real-world deployment—and is likely to reshape how future vehicles handle high-bandwidth sensor, camera, and display data.
