DESCRIPTION
The Crystal Oscillators provide generation of high stability signals.
Crystal Oscillators are widely used in communication, navigation, radiolocation systems, in frequency measurement equipment as reference signal sources and in atomic frequency standards as output signal sources.
Environmental resistance, small size, weight, power consumption and a short warm-up time allow to use Oscillators in various mobile systems and complexes.
