This section provides overview, applications, and principles of clock generators. Also, please take a look at the list of 14 clock generator manufacturers and their company rankings.
A clock generator is a device that generates a constant frequency signal called a digital clock on a steady basis. This clock serves to convey timing to electronic devices and clock generators, which can accurately oscillate signals in a wide range of frequencies according to that timing, and are indispensable devices for operating various electronic devices.
For the internal circuits of electronic devices such as personal computers to operate accurately, it is necessary to keep sending signals of a specific frequency, and clock generators are utilized for this purpose.
Clock generators oscillate at a precise frequency regularly, and the frequency and accuracy of the oscillation depend on an internal element called an oscillator.
Generally, quartz is the most commonly used crystal oscillator, but rare metals such as rubidium are also used in clock generators that require higher precision.
Inside a clock, the generator is a component called an oscillator, which is composed of a material represented by a crystal.
Populated quartz crystals, crystallized with high purity, have a property called the piezoelectric effect. Thanks to this property, the crystal can become an element that converts pressure and electricity and vibrates in response to an applied voltage.
The frequency of this vibration is determined by the way the crystal is cut, so a crystal unit that vibrates at the desired frequency can be used to produce regular vibrations in a stable manner.
Unlike signals produced by analog devices, the constant frequency vibrations produced by a crystal oscillator are highly stable because they are produced by the crystal itself, which has a high degree of symmetry. This is why clock generators can maintain a very stable clock for long periods.
Furthermore, since quartz crystals are tiny, they are an excellent match for precision electronic devices, which have become increasingly miniaturized in recent years.
