KVG is a German company with a 75+ year history focusing on the development and production of high-end frequency control products. Increasing demand for high performance crystal oscillators in mobile applications where vibrations impact 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 these applications.
This module uses an ultra-low g-sensitivity OCXO encapsulated in a specially developed mechanical vibration damping system. The 80 x 80 x 50 mm package weighs less than 600 g. The damping system resonant frequency is 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 temperature, altitude, vibration and shock conditions, specified by MIL-STD-810G Change Notice 1 and RTCA DO-160G. This module is ideally suited for civil and military airborne applications.
It exhibits outstanding dynamic phase noise under harsh vibration conditions. With random vibration from 10 Hz to 2 kHz and acceleration spectral density of 0.02 g2/Hz, the D-RUG 100 MHz module improves dynamic phase noise at frequency offset of 100 Hz and beyond significantly, compared to an uncompensated OCXO. The dynamic phase noise from 1 kHz is as good as the static phase noise.
