Crystals: LFXTAL028710BULK and Its Applications
Crystals are solid materials whose atoms and molecules are arranged in a three-dimensional, orderly and periodic array. They are commonly used in electronic and optical devices, such as oscillators, filters and frequency multipliers, for their special physical and electrical properties. Crystals divided into three types on the basis of their size and functionality: Quartz crystals, Multi-Layer Ceramic Capacitors (MLCCs), and Plastic Encapsulated Microcircuits (PEMs). Among them, quartz is often selected due to its stability and relatively high dielectric strength.
LFXTAL028710BULK is a type of quartz crystal which is a low frequency, low noise, high temperature resistant, and low power consumption device, specifically employed in many communication, navigation and monitoring systems. Both its application and working principle are unique. Let us take a closer look at both of these aspects.
Application field of LFXTAL028710BULK
This crystal is mainly used in a variety of electronic systems and devices, such as:
- Wireless communication systems
- GPS location and navigation systems
- Radio frequency identification (RFID) systems
- Automatic control systems
- Timing measurement devices
- Satellite communication systems
- Television transmitters and receivers
- Data storage, retrieval and analysis systems
- Industrial automation systems
The ability to keep accurate time and frequency even at high or low temperatures is one of the most important characteristics of LFXTAL028710BULK. The device can maintain an accurate frequency even in the presence of temperature changes, such as those that happen in a car or a plane. This makes the crystal suitable for use in these types of environments.
Another great feature is the low power consumption, which makes LFXTAL028710BULK perfect for use in portable and battery-operated devices as well. And due to its low noise operation, it also is a great choice for applications that require quiet and accurate operation without compromising the performance of the whole device.
Working principle of LFXTAL028710BULK
LFXTAL028710BULK works by taking in oscillation signals and amplifying them. The crystal is composed of two specific components: a resonator and an amplifier. The resonator is composed of two plates: first, a quartz plate which is cut in a manner that allows it to vibrate at its own natural frequency, and second, a metal plate. The amplifier amplifies the signal of the resonator, and then it is sent to the circuit.
By taking advantage of the quartz’s piezoelectric properties, the resonator produces two electric charges each time it vibrates. The piezoelectric effect is the electrical charges that are produced when a crystal material is deformed. When the quartz crystal vibrates, it causes an electrical oscillation in the metal plate, which is then amplified further by the amplifier.
The resonator oscillates at its natural frequency, which is determined by its size, shape, and material. The frequency of the oscillation is used to generate a very stable, accurate, and low-noise electrical signal. This signal is then used to control and synchronize other electrical systems, such as radio receivers and transmitters, clocks, watches and telecommunication systems.
Conclusion
Owing to its many advantageous features, such as low noise, high temperature resistance, and low power consumption, LFXTAL028710BULK is widely used in various communication, navigation and monitoring systems. The crystal is composed of a resonator and an amplifier, thereby taking advantage of the quartz’s piezoelectric properties to generate a very stable, accurate, and low-noise electrical signal. This makes the crystal an indispensable element in many electronic systems.
