Oscillators – FN7770025 Application Field and Working Principle

Oscillators are regularly used to generate repetitive waveforms. There is no single solution that is suitable for all purposes, and the specific application will dictate the particular oscillator design to be used. The FN7770025 is an oscillator which is mainly designed for applications in the telecommunication, automotive, and computing fields.

Design Features

The FN7770025 is a Surface Mount Crystal Oscillator (SMXO). This oscillator has been designed with many features that make it very attractive for its intended markets. It operates over a wide range of frequencies, from 1.3 MHz to 39 MHz. It is also very small, measuring only 2.93 x 1.6 mm, which makes it well suited for high density PC boards.The FN7770025 has a temperature range of -20°C to + 70°C. This makes it suitable for use in environments that are subject to wide fluctuations in temperature. The frequency accuracy of the device is 1 ppm over the specified operating temperatures, which is ideal for applications such as timing circuits in automotive engines.

Working Principle

The most common type of oscillator is the LC oscillator, which consists of an inductor and a capacitor connected in series to form a resonant circuit. The oscillations of the current flowing through this circuit are generated by the interaction between the inductor and capacitor.The FN7770025, however, uses a crystal as the resonant element and so is classified as a crystal oscillator. The circuit consists of an oscillator circuit and the crystal itself. The crystal is made of a piezoelectric material, which means that it can vibrate when an electric voltage is applied to it. This vibration is converted to an alternating current which is used to generate the required oscillation.

Noise Suppression

Noise suppression is important in timing circuits, as it can result in the output being jittery and inaccurate. The FN7770025 has two built-in noise suppression circuits. The first is a built-in shield that surrounds the oscillator, which helps to reduce RF interference. The second is an internal filter, which helps to reduce the effect of noise on the output signal.

Conclusion

The FN7770025 is a Surface Mount Crystal Oscillator that has been designed for use in communication, automotive, and computing applications. It is small, has a wide frequency range, and has good temperature accuracy and noise suppression capabilities. The working principle of the FN7770025 is based on the use of a crystal oscillator that is driven by an electric voltage, and the oscillations created are used to generate the required output waveform.
