Vibration Isolated HF Citrine PLO

DESCRIPTION

The Vibration Isolated HF Citrine PLO is a 10 MHz to 25 MHz fixed frequency rugged OCXO integrated with a low noise phase lock loop circuit and mounted within an outer enclosure using shock mounts. The PLO offers excellent aging and temperature stability (when free-running), Standard or Premium phase noise options and low g-sensitivity (to 1E-10/g per axis). Frequency dividers are used to prescale the internal HF oscillator and the external reference frequencies to phase lock at a common lower frequency. The PLL loop bandwidth is typically ≤ 1 Hz, but can be configured for optimal performance considering the reference signal provided. 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. The Vibration Isolated HF Citrine PLO 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 3.25” x 3.05” 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.
