Magic Xtal Ltd MXO37/14P Only Magic Technologies! Revised in November 2014 Ultra Low Power High Stability Miniature OCXO Features 9.3mm height 14 DIP compatible 14DIP Compatible 9.3mm Height Packaging Very Low Power Consumption (0.18W at +25°C) High Stability (up to ±3x10-9 over -40°C to 85°C) Fast Warming-up 60 s (to 15 s – spec. option) Low Phase Noise (-173 dBc/Hz floor at 100MHz) Low Aging (2x10-10/day, 2x10-8/year) Wide Frequency range (8 – 150 MHz) NEW! Typical Applications Portable Wireless Communications Mobile Test equipment Synthesizers Battery Powered Application RoHS compliant Description The МХО37 series utilizes the internal heating resonator (IHR) technology incorporating the whole oven system together with the crystal plate inside the TO-8 vacuum holder. Such OCXO concept results in radical reduction of its volume, power consumption and warm-up time. The novel MXO37/14P version differs from the basic MXO37/14 model by improved oscillator circuitry providing essentially better temperature stability at the same miniature sizes, extremely low power consumption and low phase-noise level.
