The HF Citrine PLO is a 10 MHz to 25 MHz fixed frequency rugged OCXO integrated with a low noise phase lock loop circuit. 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. Designed for demanding applications, the HF Citrine PLO provides excellent phase noise performance under vibration with both hard mount and a vibration isolated version available. The hard mount nickel-plated machined aluminum package is 2.25” x 2.25” x 1.3”. 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.
