·The OpenGMSL standard is based on the industry-leading gigabit multimedia serial link technology GMSLTM, providing an open standard for video and/or high-speed data transmission. The application and innovation of this standard will reshape the development of autonomous driving, advanced driver assistance systems (ADAS), and information entertainment systems.

Beijing, China, June 4, 2025- Several leading automotive original equipment manufacturers (OEMs), first tier suppliers, semiconductor manufacturers, and ecosystem partners have jointly announced the establishment of the OpenGMSL Alliance, aimed at bringing together industry forces to build SerDes transmission of video and/or high-speed data into an open standard for the global automotive ecosystem.

From ADAS (Advanced Driver Assistance Systems) to infotainment systems and autonomous driving, the demand for various modern automotive systems is rapidly growing. ADAS visual systems heavily rely on high-quality video data to make critical real-time decisions, thereby improving driving safety and reducing accidents. Meanwhile, touchscreen infotainment systems require high-speed, low latency connections to provide a smooth immersive user experience. The above factors have increased the development cost of new car models, made integration more complex, suppressed innovation, and ultimately delayed the improvement of safety performance.

OpenGMSL standard unveiled

With the establishment of the OpenGMSL Alliance, participation in OpenGMSL global standards will help promote autonomous driving ADAS、 Innovation in information entertainment and other applications. OEMs and suppliers will be able to leverage efficient collaborative solutions to accelerate product launch and reduce operating costs.

The OpenGMSL standard is based on ADI's industry-leading and road tested Gigabit Multimedia Serial Link (GMSL) technology. Paul Fernando, Chairman of the OpenGMSL Alliance, stated that the shipment volume of GMSL ICs has exceeded 1 billion units and has been adopted by over 25 OEM car manufacturers and 50 first tier suppliers worldwide. GMSL is one of the most mature and road tested high-speed video link technologies in the automotive industry. Based on this solid foundation, OpenGMSL will accelerate innovation in autonomous driving, ADAS, and next-generation information and entertainment technologies, helping existing thriving ecosystems move towards an open and collaborative future. ”

The OpenGMSL Alliance is a non-profit entity with an independent board of directors and encourages broad participation from all parties worldwide. Products developed using the OpenGMSL standard require mandatory compliance testing to ensure seamless interoperability between products from different suppliers.
