A small part from SiTime runs a big part of your world

Whether you're building medical devices, space shuttles, railways, or factory machinery, timing is critical.

If timing fails…

  • An airplane's landing gear may not descend at the right time
  • Robotic surgeries could be compromised or even stop in the middle of a procedure
  • An earthquake detection system may fail to alert residents nearby

Industrial equipment is exposed to vibration, shock, and high temperatures. That's a challenging environment for quartz timing devices. Our MEMS timing solutions are designed to perform better and perform longer in these extreme conditions.
