Company: SiTime

Entry Statement

SiTime Endura VCXOs provide exceptional dynamic performance and high reliability for defense and aerospace
applications. These ruggedized devices are engineered to maintain phase noise performance and frequency tuning
accuracy in harsh environmental conditions.

Ruggedized platforms often operate in the most hostile environments. Aerospace and defense systems
can be exposed to extreme temperatures or large magnitude shock and vibration events. Reliable
operation under such harsh conditions couldn’t be more important, and in some circumstances could
make the difference between mission success or mission failure. Because MEMS-based timing products now exceed the
performance of traditional quartz oscillators in many performance categories, it is ideally suited to meet the challenges
of aerospace and defense.

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. 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.
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.
