OCXO oscillator 9500B Space

electromechanicallow phase noise

The 9500B delivers the best stability performance available in a commercial space-qualified quartz oscillator. The 9500B is a high performance oven-controlled quartz crystal oscillator that produces a highly stable, low noise reference frequency output. It is particularly suited to space applications, and can be used as the on-board frequency reference for a satellite or its ground station. High Performance The 9500B features a 3rd overtone SC-cut quartz resonator which, along with its sustaining electronics, is completely enclosed in an insulating dewar and then kept at a precisely controlled temperature. The result is excellent short-term stability, phase noise, and aging characteristics. Ruggedized for Satellite Installations Assembly is performed by skilled operators certified to J-STD-001DS approved workmanship standards. All EEE parts on the 9500B are selected in accordance with MIL-STD-975/PPL-21 for Grade 1 or Grade 2 applications, and are procured from approved QML/QPL sources of supply. Key Features Output frequency: Standard 5 MHz & 10 MHz (contact Microsemi for alternate frequency requirements, available from 4 -100 MHz) Power consumption: 100 kRad (Si), ELDERS, neutron and SEE hardened Frequency aging @ 5 MHz: <5.0E-11/day, <1.0E-8/year
