The increasing demand of high-class crystal oscillators in mobile applications, where vibrations have an impact on performance, led to the development of our vibration isolated OCXO D-RUG module. It is designed to avoid the phase noise deterioration of crystal oscillators in such applications. This module adopts an ultra-low g-sensitivity OCXO encapsulated in a specially developed mechanical vibration damping system. The package size is 80 x 80 x 50 mm and the weight is less than 600 g. The resonance frequency of the damping system is kept below 40 Hz. It has excellent dynamic phase noise performance at a frequency offset of 100 Hz and beyond. The effective g-sensitivity can be improved by a factor of 10 at 100 Hz and by a factor of 100 at 1 kHz. It guarantees reliable performance under harsh environment conditions in terms of temperature, altitude, vibration and shock, specified by MIL-STD-810G Change Notice 1 and RTCA DO-160G. This module is ideally suited for civil and military airborne applications.
