Magic Xtal Ltd MXODR Only magic technologies! Miniature Ultra High Stability OCXO Revised in November 2014 Features Packaging: 20.2 x 20.2 x 12.9 mm Miniature 5 ccm packaging High stability - to ± 1x10-10 over -30 to +70°C Low aging rate - to ± 2x10-10/day, 2x10-8/year Low Allan variance value – up to 3x10-12 at 1s Frequency range: 8 to 100 MHz Typical Applications Rubidium Standard Replacement GPS Disciplined Frequency Standards Instrumentation Communication Systems RoHS compliant Description The МХОDR series combines advantageous of the double-oven and internal heated resonator (IHR) technologies providing smallest in the class 5 ccm volume and less than 1W power consumption at as high as 0.1 ppb temperature stability and 0.2 ppb/day aging (for 10MHz). The MXODR oscillators are excellent to use in high-end clock systems, instrumentation, and other applications where utmost frequency stability should go along with the smallest sizes.
