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

Highlights

• 4 parts per trillion per g force of acceleration – 50 times better than quartz
• Supports -55°C and +125°C operation
• Key timing specifications conform to MIL-PRF-55310
• Maximum choice – 5 million possible part numbers

SANTA CLARA, Calif., July 23, 2019 — SiTime Corporation, a market leader in MEMS timing, today 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.

SiTime’s +105°C Elite Super-TCXOs Named Product of the Year by Electronic Products Magazine

MEMS Timing Devices Recognized for Enabling 5G Anywhere with Best Dynamic Performance and 30x Better Reliability

SANTA CLARA, Calif., January 23, 2019 —SiTime Corporation, a leading provider of MEMS timing, today announced that its +105°C Elite Platform™ Super-TCXOs™ have been named the Product of the Year by Electronic Products magazine in the Analog/Mixed-Signal ICs category.

“The SiTime Elite Platform Super-TCXOs are outstanding timing products with high-performance features, including high dynamic stability, ultra-low jitter, wide frequency range, and programmability,” said Gina Roos, editor-in-chief, Electronic Products. “These are high-frequency and tight-stability TCXOs that deliver ±100-ppb frequency stability over an extended temperature range up to 105°C, enabling them to be used in a wide range of high-reliability end markets from networking and RF/wireless to avionics and defense and including 5G applications.”

From thousands of products launched in 2018, the editors of Electronic Products have chosen those they feel are among the most outstanding. As always, the selection is based on a significant advance in technology or its application, innovation in design, or gain in price/performance.

“5G’s goal of delivering multi-gigabit bandwidth with very low latency requires a 10x improvement in timing and synchronization performance. As 5G equipment is deployed closer to the consumer, in uncontrolled environments, the timing system needs to sustain its performance in the presence of environmental disturbers such as vibration, shock, high temperature and fast thermal ramps,” said Piyush Sevalia executive vice president of marketing at SiTime. “SiTime’s Elite Platform Super-TCXOs exceed 5G’s timing requirements and enable 5G to be deployed anywhere. We’re honored that Electronics Products has recognized the unique capabilities of the Elite Super-TCXOs with their prestigious Product of the Year award.”
