We’re redefining what timing can do. In a world scaling faster than ever, from AI data centers to 5G base stations to autonomous platforms, timing and synchronization have become mission critical. Legacy analog clocks can no longer keep pace. That is why we built a fully digital architecture based on CMOS technology. It delivers femtosecond level jitter, unmatched stability, and the flexibility to scale across a wide range of applications. We do more than provide industry leading multi-gigahertz performance. We work side by side with engineers at the core of system design to simplify integration and overcome the limitations of traditional solutions. Our clocks are made for rugged environments, real world demands, and the most advanced platforms on the planet. With agile design and scalable deployment, Mixed-Signal Devices is synchronizing the fastest systems in the world.
