SiTime Introduces MEMS Timing Solutions for Airborne and Cold Temperature Terrestrial Applications

SiTime Corporation, a provider of MEMS timing solutions, has announced the availability of a significant new feature of the SiTime Endura SiT5146 Super-TCXO, EverythingRF reports.


Previously, these devices operated down to -40°C, but can now operate at temperatures as low as -55°C. With this new capability, the SiT5146 delivers stability from -55ºC to +105ºC, benefiting airborne applications such as low earth-orbiting (LEO) satellites, commercial aircraft, satellite communication systems, and rocket delivery systems as well as terrestrial systems residing in extremely cold environments.

Piyush Sevalia, executive vice president of marketing at SiTime said that aerospace and defense applications depend on precise and stable timing in the presence of extreme temperatures. While the challenge is significant, SiTime solves their customers’ difficult timing problems. Through their rapid-release derivatives program, they extended the operating temperature range of the SiT5146 to -55°C while maintaining ±1 to ±2.5 ppm stability and excellent performance in the presence of shock and vibration. With these features, the Endura SiT5146 becomes an obvious choice for airborne and terrestrial applications that operate in extremely cold environments.
