OCXO Specification IQOV-74 ISSUE 1; January 2016 Outline (mm) Description The IQOV-74 Oven Controlled Crystal Oscillator (OCXO) is from the world's first ASIC-based OCXO family using patented ASIC technology. This Stratum 3 compliant oscillator delivers stability as low as ±10ppb over -20 to 70°C and is capable of short-term ageing typically less than ±2ppb/day. The highly integrated oven ensures short warm-up times and low power consumption of typically 350mW at room temperature. The ASIC architecture delivers 1000x reliability improvement compared to traditional OCXOs and is available in a 14pin-DIL package. For specific enquiries please contact one of IQD’s Sales Offices where we can tailor a unique specification to meet your needs. Features: Frequency stability over temperature as low as ±10ppb over -20 to 70°C. Low power consumption. High reliability.

Note: Parts should be shielded from drafts causing unexpected thermal gradients. Temperature changes due to ambient air currents can lead to short term frequency drift. The characteristics of the component may be temporarily affected by the processes of assembly and soldering. The frequency specifications apply 48hrs after assembly. Nominal conditions apply unless otherwise stated.
