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.
