Oscillators

An oscillator is an electronic circuit that produces a steady, repetitive waveform. Oscillators are commonly used in many different types of electronic systems to generate a reference clock signal or create other waveforms useful for various purposes. One example of an oscillator commonly used in today’s products is the AST3TQ-30.720MHZ-5-T. In this article, we will discuss the application field and working principle of this device.

Application Field

The AST3TQ-30.720MHZ-5-T is a low noise oscillator designed with quartz crystal resonators to produce a constant frequency signal with accuracy up to ±50ppm. This makes it suitable for various applications such as clock synchronization, telecommunication, automotive electronics and many more. This oscillator is also available with frequency range from 16MHz to 110MHz, allowing it to be used in a wide variety of different applications.

Working Principle

The AST3TQ-30.720MHZ-5-T works on a principle called crystal oscillation. A quartz crystal is an extremely precise frequency-determining element, which is placed between two electrical contacts. When an alternating current is applied to the contacts, the crystal experiences an alternating electric field which causes the crystal to vibrate at its resonant frequency. This frequency is determined by the physical dimensions of the crystal. In the case of the AST3TQ-30.720MHZ-5-T, the resonant frequency is 30.720MHz.

The output of the device is amplified to produce a stable waveform at the resonant frequency. The oscillator also features a frequency trimming function, allowing the frequency to be adjusted within a range of ±50ppm to ensure maximum accuracy of the output frequency.

Conclusion

The AST3TQ-30.720MHZ-5-T is a low noise oscillator designed for applications such as clock synchronization, telecommunication, automotive electronics and many more. The device works on the principle of crystal oscillation to produce an output frequency of 30.720MHz with an accuracy of up to ±50ppm. This oscillator also features a frequency trimming function for maximum accuracy of the output frequency.
