The components of a crystal oscillator are essential to the proper function and stability of the oscillator, which is why SCTF prides itself on offering products with oscillators that have been properly manufactured and protected from external stresses and environmental changes. Typically, a crystal oscillator will consist of a ceramic package, integrate circuit with quartz crystal. IC was bonded with wire and quartz crystal is attached by conductive epoxy on the package, and then the whole package is sealed hermetically under N2 condition.
