Description
The МХО37 series utilizes the internal heating resonator technology (IHR) with arrangement of the oven system together with
the crystal plate inside the TO-8 vacuum holder. Such approach results in radical reduction of the OCXO sizes, power
consumption and warm-up time. Compared with the basic MXO37/8 series the new model contains improved oscillator
circuitry providing operation at higher fundamental frequencies at substantially better temperature stability and lower phasenoise level. The MXO37/8P is excellent solution for various portable or/and battery fed applications with elevated
requirements to frequency stability and phase-noise of the OCXO.
