Endura MEMS timing products. (Photo: SiTime) SiTime Corp. has unveiled its Endura micro-electro-mechanical system (MEMS) timing solutions for aerospace and defense applications including precision GNSS, as well as field and satellite communications, avionics and space. The Endura products are engineered to provide high performance in harsh conditions — severe shock, vibration and extreme temperature — that are routinely experienced in these applications. SiTime offers customers 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.” Highlights of the company’s solutions include: 4 parts per trillion per g force of acceleration (50 times better than quartz) Supports –55 degreesCelsius and +125 degrees Celsius operation Key timing specifications conform to MIL-PRF-55310 Five million possible part numbers Endura Super-TCXOs (temperature compensated oscillators) for use in high-speed communications and GNSS applications include: SiT5146/SiT5147 – 1 to 220 MHz, ±0.5 to ±2.5 ppm, -40 degrees Celsius to +105 degrees Celsius SiT5346/SiT5347 – 1 to 220 MHz, precision ±0.1 to ±0.25 ppm, -40 degrees Celsius to +105 degrees Celsius SiT5348/SiT5349 – 1 to 220 MHz, ultra-precision ±0.05 ppm SiTime’s 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.
