DSC1030BI1-020.0000T

Application Field

The DSC1030BI1-020.0000T is a quartz oscillator that is commonly found in watches and other timekeeping devices. It is an essential component in the development of devices that require a stable, accurate reference time signal, such as those used for scientific measuring instruments as well as for the global positioning system. It is also used as a frequency reference in radio frequency applications, as well as in other professional audio and video applications.

Working Principle

The DSC1030BI1-020.0000T oscillator works on the piezoelectric principle. Quartz is a material that has a quality known as "piezoelectricity,” meaning that when a physical force is applied to it, it creates an electrical charge. The DSC1030BI1-020.0000T oscillator harnesses this property of quartz and uses it to produce a stable time signal.

In the oscillator, a crystal oscillator is made up of a quartz crystal that is cut into a particular shape and then mounted onto an electronic circuit. When an alternating current is applied to the crystal, it vibrates at a fixed frequency: the same frequency at which it is excited. The frequency of the oscillator is determined by the shape of the quartz crystal and is usually in the range of 32.768 kHz. This frequency is known as the resonant or natural frequency of the crystal. The output of the oscillator is a precise square wave with a frequency that is exactly double of the resonant frequency.
