A new generation of veryhigh stability BVA oscillators

International audienceA third generation of “Oscilloquartz” OCXO's using the technique of housing a BVA SC-cut crystal resonator and its associated oscillator components in double oven technology has been developed with the funding support of European Space Operations Centre (E.S.O.C). The main purpose is to provide a local oscillator for high performances ground clock. The main features targeted of that new “8607-C series” are to get significant improvements compared to the classical “state of the art” 8607-B design in a better short term stability @ 1 sec in Allan variance, a better-low phase noise and outstanding short term stability and a better-high isolation from “pressure and humidity” variations
