Crystal oscillator is an electronic oscillator circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a precise frequency. The most common type of piezoelectric resonator used is the quartz crystal, so oscillator circuits incorporating them became known as crystal oscillators.

Quartz crystals most are used for consumer devices, inside test and measurement equipment, such as wristwatches, clocks, radios, computers, cellphones, counters, signal generators, and oscilloscopes.

Kingtronics produce below Quartz Crystals and Oscillators, with good price and quality. Welcome check our product link and send your inquiry to us! 

Quartz Crystal Advantages:

Quartz Crystal

Crystal Oscillator

Application:  
* Widely used in :Communications, such as ADSL, routing, Intercom, IP telephone, WiFI, GPS, RF module,etc.;
* Security, such as monitoring cameras, Entrance guard systems, anti-theft devices, etc.;
* Consumers, such as car stereos, DVB, smart metering, remote control toys, MP3, MP4, wireless microphones, digital frame, card reader, etc.

A quartz crystal resonator depends on the piezo-electric effect to work. This effect converts a mechanical stress in a crystal to a voltage and vice versa. In this way the piezo-electric effect converts the electrical impulses to mechanical stress which is subject to the very high Q mechanical resonances of the crystal, and this is in turn linked back into the electrical circuit.

The quartz crystal can vibrate in several different ways, and this means that it has several resonances, all on different frequencies. Fortunately the way in which the quartz crystal blank is cut from the original crystal itself can very significantly reduce this. In fact the angle of the faces relative to the original crystal axes determines many of its properties from the way it vibrates to its activity, Q, and its temperature co-efficient. There are three main ways in which a crystal can vibrate: longitudinal mode, low frequency face shear mode, and high frequency shear. A cut known as the AT cut used for most crystals used in traditional radio and electronics circuits uses the high frequency shear mode.

Vibrational modes of a quartz crystal resonator
(For the sake of clarity, the movements have been greatly exaggerated)

Quartz is used in the making of sandpaper, optics, glass, liquid filters, circuit boards, computer components, cement, mortar, and jewelry. Quartz crystals are also piezoelectric meaning when an electrical current passes through them they vibrate a small amount. Time can be measured from the vibrations of the quartz crystals so quartz crystals are often used in clocks.

Quartz crystals may either operate in a fundamental mode or in an overtone mode. Below frequencies of around 25 MHz crystals are normally designed to operate in their fundamental mode, whereas above this they will normally be designed for overtone operation, although with manufacturing techniques improving higher frequency crystals are becoming available. The mode is therefore an important element of the crystal specification.
