New 9250 combines unique low g sensitivity oven controlled crystal oscillator in low profile package for next generation communications, navigation and targeting systems.

Symmetricom, Inc. (NASDAQ: SYMM), a worldwide leader in precise time and frequency products and services, today announced the new 9250, a unique military oven controlled crystal oscillator (OCXO) that combines low g sensitivity in a small, low profile package. The 9250 is designed for applications where low g sensitivity and low phase noise are critical application design parameters.

Space avionics and military platforms are some of the most demanding precise time and frequency applications where the environment is the harshest, the need for accuracy the greatest and the price for failure the highest,” commented Doug Lowie, product manager for Symmetricom. “These customers continue to demand improved phase noise and superior frequency stability to meet the needs of next generation Communications, Navigation and Identification (CNI) and we are in position to meet these increased requirements with the new 9250.”

The Symmetricom 9250 military OCXO is designed for ground tactical and airborne applications where superior frequency stability and phase noise are required. Advanced communications, navigation and targeting systems require precision oscillators that can withstand a wide range of operating environments with minimal degradation in frequency accuracy and stability. Part of a new family of low g oscillators from Symmetricom that support these applications, the 9250 uniquely combines excellent frequency stability and low dynamic phase noise in a small, low profile package. The 9250 achieves less than –100dBc phase noise at 1Hz from the 10MHz carrier.

Symmetricom designs and manufactures highly stable and precise rubidium, cesium and quartz oscillators for instrumentation and satellite applications. These oscillators are available in stand-alone and embedded frequency reference subsystems. Symmetricom’s staff includes experienced technologists who thoroughly understand the unique requirements of military environments.


The 9250 Low g Sensitivity Military Oven Controlled Crystal Oscillator (OCXO) will be shipping August 2006.
