Vibration Isolated VHF Citrine Plus


The Vibration Isolated VHF Citrine Plus is a 25 MHz to 160 MHz fixed frequency rugged OCXO coupled with an additional circuit such as a multiplier, divider, amplifier or filter, when the application demands something extra, and mounted within an outer enclosure using shock mounts. This integrated assembly can provide a fixed output frequency between 50 MHz and 700 MHz and offers good temperature stability, Standard or Premium phase noise and low g-sensitivity (to 2E-10/g per axis). Although vibration isolation may not be a viable solution for some applications, it works well for dampening vibration beyond the natural resonant frequency of the isolated unit, typically 30 Hz to 50 Hz, and varies depending on the weight of the isolated unit and vibration profile. This unit is an ideal solution for airborne and mobile applications with random vibration requiring improved dynamic phase noise performance at offsets at and beyond 80 Hz. Effective g-sensitivity to 5E-12/g (2 kHz offset) can be realized. The nickel-plated machined aluminum outer enclosure is 3” x 2.8” x 1.75”. An internal voltage regulator is provided for excellent power supply line rejection. Please consult the factory if you need any specifications to be modified to better suit your application.
