Oscillators - ABDFVCTCXO-19.200MHZ-E-2-CT application field and working principle

Introduction

Oscillators are electronic components that generate an oscillating signal with a constant amplitude and frequency. They are widely used in plodding, communication, measurement and control systems as clock or timing references.The ABDFVCTCXO-19.200MHz-E-2-CT oscillator is a miniature, analog, quartz oscillator component designed for low noise, low power operation and a low-temperature coefficient. This oscillator is widely used in portable and mobile communication systems and mobile devices due to its small size and low power consumption.

Application Field

The ABDFVCTCXO-19.200MHz-E-2-CT oscillator is designed to meet demand for high reliability, low-noise, and low-temperature-coefficient oscillators in demanding applications. Its frequency range is 19.200MHz with a stability of ±2 ppm maximum across the full environmental range of -40°C to +85°C. It is suitable for communication and mobile devices, portable applications, and more demanding applications where redundancy and reliability are required.

Working Principle

The ABDFVCTCXO-19.200MHz-E-2-CT oscillator is a quartz oscillator that utilizes a vibration piezoelectric effect of crystal to generate a signal with a precise and fixed frequency. The quartz crystal is placed between two electrodes and oscillates at its own frequency when an AC voltage is applied. The frequency is determined by the size and shape of the crystal, and by the capacitance inside the quartz oscillator.The oscillator is a VCTCXO (Voltage-Controlled Temperature-Compensated Crystal Oscillator). It utilizes a temperature-compensated circuit to compensate for the changes in the crystal oscillator frequency due to temperature variations. The temperature-compensated circuit automatically increases or decreases the drive voltage applied to the crystal to maintain the stability of the output frequency.

Conclusion

The ABDFVCTCXO-19.200MHz-E-2-CT is a miniature, low-power, quartz oscillator component designed for a range of applications requiring low-noise and low-temperature-coefficient oscillators. It utilizes a piezoelectric effect of crystalline quartz to generate a signal, and a temperature-compensated circuit to maintain the stability of the frequency. The oscillator is suitable for demanding applications such as communication and mobile devices, portable applications, and where redundancy and reliability are required.
