In a landmark move to streamline and accelerate the future of connected and autonomous mobility, a coalition of leading OEMs, Tier-1 suppliers, semiconductor firms, and ecosystem partners has come together to form the OpenGMSL Association. The new consortium aims to establish a global open standard for Gigabit Multimedia Serial Link (GMSL)-based SerDes (Serializer/Deserializer) transmission of high-speed video and data across automotive platforms.
As automotive systems become increasingly data-driven—with advanced driver-assistance systems (ADAS), infotainment, and autonomous driving pushing bandwidth and latency limits—there is a critical need for interoperable, high-performance communication frameworks. The OpenGMSL Association is set to address these demands by leveraging Analog Devices Inc.’s (ADI) road-proven GMSL technology, which has already seen over a billion integrated circuits shipped globally.
Building a Global Open Standard
OpenGMSL’s foundational technology—ADI’s GMSL—has been adopted by more than 25 OEMs and 50 Tier-1 suppliers worldwide. The new association will convert this proprietary success into an open standard that promotes innovation, reduces integration complexity, and lowers development costs. Products developed under the OpenGMSL banner will undergo mandatory compliance testing to ensure cross-vendor interoperability.
Paul Fernando, President of the OpenGMSL Association, said, “OpenGMSL builds on GMSL’s mature and proven legacy to push boundaries in autonomous driving, ADAS, and next-gen infotainment. This is about taking a thriving technology and turning it into an open, collaborative future.”
Widespread Industry Backing
The initiative has received widespread industry endorsement:
- ADI’s Yasmine King highlighted the company’s commitment to easing complexity for OEMs through precision sensing, edge processing, and robust connectivity.
- GRL’s CEO Vamshi Kandalla emphasised how the standard will accelerate deployment of connected and autonomous vehicles globally.
- GlobalFoundries’ Sudipto Bose pointed to the importance of manufacturing-ready, power-efficient silicon to support OpenGMSL adoption across geographies.
- Hyundai Mobis’ HH Lee welcomed the move to standardise GMSL, noting its longstanding use in their vehicles.
- Fred Jarrar of Indie Semiconductor stressed the need for open standards to fuel innovation in evolving automotive architectures.
- Keysight Technologies’ Thomas Goetzl reaffirmed their support in test and validation to mature the compliance ecosystem.
- Rohde & Schwarz, Teledyne LeCroy, and others echoed their commitment to supporting OpenGMSL through their testing and development expertise.
Collaborative Path Forward
Structured as a non-profit with an independent board of directors, the OpenGMSL Association invites participation from across the global automotive supply chain. By fostering a collaborative environment rooted in tested technology, it aims to accelerate the rollout of safe, high-speed, and standardised in-vehicle data transmission systems.
With real-time data playing an increasingly pivotal role in vehicle safety and performance, OpenGMSL’s launch marks a decisive step toward ensuring that the underlying communication infrastructure is both future-ready and industry-wide.
