Helium can cause oscillatkr issues when it diffuses through glass enclosures of rubidium standards. Consider splitting it into new pages, adding subheadingsor condensing it. Harmonics are an exact integer multiple of the fundamental frequency.

Whitaker 23 December A technique used in the world of amateur radio for slight decrease of the crystal 11.0592mhx may be achieved by exposing crystals with silver electrodes to vapors of iodinewhich causes a slight mass increase on the surface by forming a thin layer of silver iodide ; such crystals however had problematic long-term stability.

The large ones are large enough to allow some osclllator of smaller ions and molecules through the crystal. The most common type of piezoelectric resonator used is the quartz crystal, so oscillator circuits incorporating them became known as crystal oscillators, [1] but other piezoelectric materials including polycrystalline ceramics are used in similar circuits.

An oscillator crystal has two electrically conductive plates, with a slice or tuning fork of quartz crystal sandwiched between them. They are also often incorporated in a single package with the crystal oscillator circuit, shown on the righthand side.


Techniques minimize the phase noise in crystal oscillator circuits. This is generally minimized by ensuring that the maintaining circuit has insufficient gain to activate unwanted modes. The composition of the crystal can be gradually altered by outgassing, diffusion of atoms of impurities or migrating from the electrodes, or the lattice can be damaged by radiation.

Low drive levels are better for higher stability and lower power consumption of the oscillator.

The relative orientation of the acceleration vector to the crystal dramatically influences oscillwtor crystal’s vibration sensitivity. Wikimedia Commons has media related to Crystal oscillators.

The mounting and contacts may undergo relief of crystap built-in stresses.

It has well known and repeatable characteristics.

Some cuts are less sensitive to stresses; the SC Stress Compensated cut is an example. When the field is removed, the quartz generates an electric field as it returns to its previous shape, and this can generate a voltage. High-purity quartz crystals are grown with especially low content of aluminium, alkali metal and other impurities and minimal defects; the low amount of alkali metals provides increased resistance to ionizing radiation.


Retrieved August 24, Silver can be passivated by exposition to iodine vapors, forming a layer of silver iodide. Another quality indicator is the etch channel density; when the crystal is etchedtubular channels are created along linear defects.

Oscillators, whether they are crystal oscillators or others, are designated with the class letter G G1, G2, etc. From Wikipedia, the free encyclopedia.


These cuts operate at bulk acoustic wave BAW ; for higher frequencies, surface acoustic wave SAW devices are employed. Microwave and Wireless Synthesizers: Silver and aluminium are often used as electrodes; however both form oxide layers with time that increases the crystal 11.05922mhz and lowers frequency. Other influencing factors are the overtone used, the mounting and electrodes, impurities in the crystal, mechanical strain, crystal geometry, rate of temperature change, thermal history due to hysteresisionizing radiation, and drive level.

Strip resonators, usually AT cuts, are oscillattor and therefore less sensitive to mechanical shocks. SC-cut crystals are most advantageous where temperature control at their temperature of zero temperature coefficient turnover is possible, under these circumstances an overall stability performance from premium units can approach the stability of Rubidium frequency standards.

Although crystal oscillators still most commonly use quartz crystals, devices using other materials are becoming more common, such as ceramic resonators. The result is that a quartz crystal behaves like an RLC circuit. Proceedings of the 32nd Annual Symposium on Frequency Control.
