SiTime’s Endura Timing Solutions for Aerospace and Defense –  A Standout in Ruggedized Performance

SiTime Corporation unveiled its Endura™ MEMS timing solutions for aerospace and defense applications such as field and satellite communications, precision GNSS, avionics, and space. The Endura products are engineered to offer unmatched performance in harsh conditions – such as severe shock, vibration, and extreme temperature – that are routinely experienced in these applications. The devices also offer maximum choice to customers with 5 million possible part numbers that can be created from 17 programmable products.

 

“When exposed to high levels of shock, vibration and extreme temperatures, legacy timing components have been prone to failure, degrading system performance and reliability,” said Piyush Sevalia, executive vice president of marketing. “To solve these problems, SiTime created an oscillator system of silicon MEMS, analog circuits, compensation algorithms and advanced packaging, which is designed to outperform any other available timing solution in harsh environments. For example, Endura precision TCXOs deliver 4 parts per trillion per g (ppt/g) of acceleration sensitivity, which is 50 times better than legacy quartz-based solutions. With such performance, we believe that Endura will transform the oscillator landscape in aerospace and defense.”

 

About the Endura products

SiTime’s broad portfolio of commercial off-the-shelf (COTS) Endura products spans six oscillator types and 17 products. All devices offer programmable options such as frequency, operating voltage, and stability. In addition, some devices offer specialized programmable features such as spread spectrum, pull-range, and differential output type. Endura products are available with up to two grades of acceleration sensitivity, as low as 4 ppt/g (typical). This breadth of products provides customers with a large selection and the ability to configure each device for their application requirements.

 

Endura products are also designed for continuity of supply for long-life programs. For more information and datasheets, click on the part links below.
