Better reliability than legacy quartz

Mean time between failure (MTBF) predicts the expected lifetime of a device. The higher the MTBF, the more reliable the device. SiTime has stress tested tens of thousands of oscillators and found our MEMS based oscillators to be highly reliable with quality levels among the best in the semiconductor industry, and orders of magnitude better than quartz timing devices.

In fact, SiTime timing devices are guaranteed to perform—forever. Our lifetime warranty demonstrates our commitment to producing products with the highest quality and reliability and is designed to give you added confidence of using the most reliable timing components in your application.

* SiTime oscillators are up to 50 times more reliable than comparable quartz devices.
