Oscillators are an important class of electronic circuit whose purpose is to generate a periodic signal. The ABLNO-V-81.920MHZ-T is a type of oscillator, with its application field and working principle being of particular interest in this article.

Application Field

The ABLNO-V-81.920MHZ-T is a low-cost oscillator with a wide range of uses. It is specifically designed for applications such as smart phones, navigation systems, and frequency meters, where precision is of great importance. It has a frequency stability of 8.5ppb, meaning that the frequency of the signal that it outputs can remain steady even under changing conditions. This makes it ideal for use in applications where stability over a long period of time is desired.

Additionally, this oscillator is designed for both surface-mount and through-hole mounting. This allows for its usage in a wide range of applications, as it can fit a variety of circuit designs. The relatively small size of the ABLNO-V-81.920MHZ-T, as well as its low cost, make it an ideal choice for many applications.

Working Principle

The ABLNO-V-81.920MHZ-T oscillator works by using quartz crystal as the resonator. Quartz crystals have a low temperature coefficient, meaning that they can maintain an oscillating signal with minimal drift over a wide range of temperatures. A key component of the ABLNO-V-81.920MHZ-T is the feedback oscillator circuit, which consists of two transistors in a bi-stable configuration. This circuit is responsible for maintaining the desired oscillation frequency.

The oscillator is powered by a voltage supply, usually of 3.3V or 5V. This voltage is then converted into a sinusoidal wave by the oscillator circuit. It is then compared to a reference square wave, generated by the crystal. Depending on the result of this comparison, the frequency of the oscillator is adjusted accordingly.

The oscillator will remain in this oscillation state until the voltage is removed, at which point the oscillator will switch off.

Conclusion

The ABLNO-V-81.920MHZ-T is a low-cost oscillator designed for use in applications such as smart phones, navigation systems, and frequency meters. It is powered by a voltage supply of 3.3V or 5V, and uses quartz crystal as the resonator, with a feedback oscillator circuit for maintaining the desired frequency stability. Its low cost and small size make it an ideal choice for many applications.
