Crystals: 4P250F35CET Application Field and Working Principle

Layout and crystal technology is indispensable in modern telecommunication networks, computer systems and embedded systems. The technology has enabled the development of many components and systems, including 4P250F35CET crystals. Described below are the application field and working principle of 4P250F35CET crystals.

Application Field of 4P250F35CET Crystals

4P250F35CET crystals are used in applications such as cellular base stations, P X GSM (Personal Extended GSM) networks, TDMA systems and WiFi systems. These crystals are also used in GPS, RFID, text to speech, and DVD players. Their major application field is in the industrial, medical and commercial settings allowing for the navigation and measuring of distance, time or electronic signal.

In addition, 4P250F35CET crystals are used in broadcasting and communications systems, manufacturing, automotive and defense. Furthermore, they are used in advanced point-to-point and microwave links, time base generators, digital and analog clocks, medical imaging systems, and earthquake detectors.

Working Principle of 4P250F35CET Crystals

At the heart of 4P250F35CET crystals is the frequency determined by its quartz crystal. This frequency is determined and set by a combination of the cut angle determined for the quartz and an external pull/trim capacitor. These two elements work together to to find the electrical resonance frequency.

When an electric voltage is applied to the quartz crystal, a small, electrical current flows through it. This current is periodic and inversely proportional to the quartz’s size. This current supplies the energy required to the quartz crystal, allowing it to vibrate at its fundamental, resonant frequency.

The cut angle and the external capacitor then set the amount of current that can flow through the quartz crystal as well as its electrical resonance frequency. All other characteristics, such as the shape and size of the crystal, are determined by the design requirements of a particular application.

The resonance frequency can be adjusted by an external tuning control, enabling the crystal to be “tuned” to its exact desired frequency. This tuning process can be controlled either by a dedicated electrical or electronic oscillator or by a phase-locked loop (PLL).

Conclusion

4P250F35CET crystals have a wide range of applications in various industries, from cellular base stations and GPS to RFID and medical imaging systems. The working principle of these crystals rely on the small electrical current it produces when an electrical voltage is applied to the quartz crystal, which allows the crystal to vibrate at its fundamental frequency. This frequency can be determined and adjusted with the help of external tuning. In this manner, 4P250F35CET crystals can be used in many different applications.
