Magic Xtal Ltd MXO37/R Only magic technologies! Ultra Low power Ultra High Stability OCXO Revised in November 2014 Features Packaging: 20.2 x 20.2 x 12.0 mm Miniature 5 ccm packaging Power consumption: <200 mW High stability - to ± 5x10-10 over -40 to +85°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 NEW! Typical Applications GPS Disciplined Mobile Frequency Standards Portable Instrumentation Mobile Communication Systems Battery Supply Beacons RoHS compliant Description The МХО37/R model is built on advanced internally heated resonator (IHR) technology providing combination of very low power consumption and small sizes with outstanding frequency stability in wide temperature range that is unachievable with usage of conventional OCXO designs. The unique parameters of the oscillators make it very prospective for application in various high-end portable (especially battery supplied) equipment demanding superb frequency stability at minimal power consumption and smallest sizes.
