Factory Automation

Engineer using tablet check and control automation robot arms machine

Factory automation relies on HMI (human machine interface) products to control the manufacturing process from end to end. These HMI tools, and the equipment they manage, operate in Industrial environments that can be extremely harsh. Industrial timing solution must be extremely resilient under a range of conditions including fast and high temperature swings, shock, and vibration.   

SiTime high-temp MEMS timing solutions deliver a more robust and stable reference clock with better dT/dT slope, lower jitter, higher reliability, resilience to shock and vibration.
