LFXTAL003215BULK Datasheet/PDFCrystals: LFXTAL003215BULK Application Field and Working Principle
Crystals are one of the oldest and most useful components of electronics. They are usually used to control the operating frequency of electronic circuits, and they provide good stability over temperature and environmental changes. Crystals can also be used to build resonators and are used in many high-accuracy frequency circuits. When they are used in resonators, they can be used to build oscillators, filters, and even radio receivers.
The LFXTAL003215BULK is a high quality quartz crystal from the manufacturer Murata. This crystal comes in a low profile 6.0mm x 3.2mm x 1.6mm package and is suitable for high-speed frequency control. It features an ultra-low ESR and superior quality and temperature stability.
Application Fields
The LFXTAL003215BULK is a popular choice for many applications, including:
- High frequency clock oscillators
- RF and wireless communication
- PCI Express
- USB
- GPS
- Broadcast radio
This crystal is also used in higher frequency motion control and precision timing applications.
Working Principle
The working principle of the LFXTAL003215BULK is quite simple. It is composed of a quartz crystal oscillator, which is made of a quartz crystal that has been cut and shaped to form two separate plates. The plates are held together in a special holder and a voltage is applied across it. The crystal has the property of piezoelectricity, which means it deforms slightly when a voltage is applied to it, and then returns to its original shape when the voltage is removed. This movement of the crystal causes it to create a vibration at a specific frequency. This vibration is the frequency used to control the operating frequency of the circuit.
The frequency of the crystal oscillator can be changed by changing the voltage applied to the crystal, which can be done by changing the ratio of the two capacitors used in the circuit. The frequency is also dependent on the type of quartz used and its dimensions. By changing one or both of these factors, the frequency of the oscillator can be changed to control the operating frequency of the circuit.
Conclusion
The LFXTAL003215BULK is a reliable and high-quality quartz crystal from Murata. It is suitable for a wide range of applications, from high frequency clock oscillators to PCI Express and USB. It has a very low ESR and excellent temperature stability. The working principle of this crystal is quite simple, based on the property of piezoelectricity of the quartz. By controlling the capacitors used in the circuit, the frequency of the oscillator can be changed to control the operating frequency of the circuit.
