CS20-12.288MABJ-UT Application Field and Working Principle

The CS20-12.288MABJ-UT crystal oscillator is a quartz oscillator that has become popular due to its wide operating temperature range and high stability. The crystal oscillator is a precision frequency and time-keeping element used in a variety of communications and timing applications. It has a wide range of uses in the fields of communication, computing, Avionics, industrial and medical instrumentation, clock and watch-making, etc.

Types of Crystals

There are three main types of crystals: AT-cut crystals, SC-cut crystals, and BT-cut crystals. AT-cut crystals are capable of producing a higher frequency, but have a relatively lower temperature coefficient. SC-cut crystals are the most suitable for use in oscillators, while BT-cut crystals have a low frequency.

Working Principle

The working principle of CS20-12.288MABJ-UT or any other crystal oscillator is based on the piezoelectric effect. This is the phenomenon where certain materials, such as crystals, will produce an electric potential when they are mechanically deformed. When a crystal is connected to an electric circuit, the electric potential generated by the crystal will cause it to vibrate at a frequency determined by its physical structure.

The crystal oscillator works by using a specially designed LC circuit, which consists of an inductor and a capacitor. The LC circuit is connected to a crystal, usually through an amplifier. The crystal will begin to vibrate when an alternating current is applied to the LC circuit, and the vibration will be amplified by the amplifier.

The frequency of the oscillations generated by the crystal depends on the characteristics of the crystal itself. The crystal can be tuned to a specific frequency by changing the capacitance of the LC circuit or by adding additional inductors or capacitors to fine-tune the frequency.

Applications

CS20-12.288MABJ-UT crystals are used in a wide range of applications, including cellular phones, digital television, satellite navigation systems, avionics, instrumentation, timekeeping, and medical devices.

Cellular phones use crystals to maintain a stable frequency and enable accurate timing of the digital signals. In GPS receivers, crystals are used to generate the precise timing signals required to triangulate a location. In digital television and satellite navigation systems, crystals are used to ensure accurate synchronization of broadcast and playback signals.

In avionics and instrumentation, crystals are used to ensure synchronization of data transmissions, as well as to provide accurate timing data for navigation systems. In timekeeping, crystals are used to ensure accurate timekeeping and synchronization of clocks over long distances. In medical devices, crystals are often used for precise timing and synchronization of data.
