HF Citrine Plus


The HF Citrine Plus is a 10 MHz to 25 MHz fixed frequency rugged OCXO coupled with an additional circuit such as a multiplier, divider, amplifier or filter, when the application demands something extra. The integrated unit can provide output frequencies from 1 MHz to 125 MHz and offers excellent aging and temperature stability, Standard or Premium phase noise and low g-sensitivity (to 1E-10/g per axis). Designed for demanding applications, the HF Citrine Plus 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.
