Immune to shock and vibration
Need to perform in harsh environments?
SiTime timing solutions can help.
As the world becomes more connected, electronic systems are finding their way into all corners of our lives – from the devices carried in our pockets to the dozens of sensors in our cars. But as electronic devices surround us in every type of environment, they are no longer protected from harsh mechanical shock and vibration. Not a problem for SiTime MEMS-based oscillators which are inherently immune to external disturbances.

MEMS Timing Outperforms Quartz
Since oscillators rely on vibration and mechanical resonance, external movement can couple into the device and degrade its performance, creating frequency shifts and increasing phase noise in quartz oscillators.
Without special corrective measures such as shock mounts, SiTime MEMS-based oscillators have low sensitivity to acceleration. Random or periodic mechanical vibrations found in portable devices that are exposed to significant vibration or in stationary units located near vibrating machinery or by a nearby cooling fan have little effect on SiTime products.
SiTime oscillators are inherently immune to shock and vibration. The small mass of a MEMS resonator (1000x to 3000x smaller than quartz crystal resonators) and its physical design, make them resilient against external motion.
