Crystals are solid materials that are composed of atoms, molecules or ions arranged in a definite order and its structure tends to be periodic. It forms a regular lattice structure that results in a highly ordered and balanced structure from atoms to its external shape. In generally, crystals can be divided into several classes according to their characteristics and usages, such as quartz crystals, crystal oscillators, semiconductor crystals, light-emitting crystals, laser crystals, etc. LP221F23CDT belongs to crystal oscillators, and it is widely used in communication, medical equipment, audio and video equipment, computer, etc. Now, let’s examine its application field and working principle.

Application Field of LP221F23CDT

LP221F23CDT oscillator is one kind of general-purpose crystal oscillator which not only has great temperature stability, but also has low power consumption and systematic cost. It is designed to be a “drop-in” replaceable of other crystal oscillators with the same characteristics. It is usually used in embedded systems that have audio and video input and output, such as audio amplifiers, audio mixers, video decoders, LCD and LED televisions, multimedia players, computer systems and etc.

Working Principle of LP221F23CDT

Crystal oscillators are fundamental components used to generate very precise frequency signals, and LP221F23CDT is no exception. LP221F23CDT uses quartz crystal as its core and driven by the oscillation circuit, quartz crystal can resonates at an extremely stable frequency. The quartz crystal has unique characteristics of piezoelectricity which can be used to convert mechanical stress of the crystal into electrical current. When the current flows through the crystal, it will vibrate at a certain frequency and change the current into mechanical energy. This vibrating of the crystal produces a periodic signal, and when it reaches the same level as the initial current, it will maintain the same output frequency.

L2P221F23CDT also have a circuit built in that can accurately track the frequency and gain of the oscillations. This built-in circuit helps to strengthen the stability and accuracy of the oscillator. By utilizing temperature compensated parameters, it can also achieve temperature regulating functions and minimize the drift in frequency.

Conclusion

LP221F23CDT crystal oscillator is one of the most widely used type of crystal oscillators due to its cost efficiency and reliability. While crystals have been used in various applications since then, the quartz crystal has been advanced in various fields. It has become an essential component in many areas such as audio and video equipment, computer systems, communication and medical equipment, etc. With its temperature stability, low power consumption, and technological cost, LP221F23CDT crystal oscillator has become a preferred choice for use in embedded systems as well.
