Oscillators

An oscillator is an electronic circuit that produces a repeating waveform, typically an alternating waveform, such as sine, square, triangle, or sawtooth waveforms. Oscillators can be used for a variety of applications, including clock signals, frequency reference signals, audio frequency signal generation, radar signal modulation and amplitude modulation. In this article, we will discuss the application and working principle of ASTMHTA-20.000MHZ-XC-E oscillator.

Application

The ASTMHTA-20.000MHZ-XC-E oscillator is a highly stable and accurate oscillator that can be used for a variety of applications. It has a wide range of output frequencies up to 20MHz and a very low jitter output. It is commonly used in precision timekeeping applications such as clocks, watches, radio receivers, and audio equipment. It is also used for precision frequency reference in laboratory equipment, communication equipment, and digital instruments such as oscilloscopes and counters.

Working Principle

The ASTMHTA-20.000MHZ-XC-E oscillator is a quartz crystal oscillator that uses a quartz crystal as the primary frequency-determining component. The quartz crystal is a precision frequency-determining device that vibrates at a precise frequency when charged with a direct current. This property of quartz is exploited by the oscillator to generate a precise frequency waveform. The oscillator consists of an amplifier and a quartz crystal resonator, both of which are connected to the power source. The crystal resonator is driven by an external voltage or current which cause it to vibrate at its characteristic frequency. This characteristic frequency is determined by the physical properties of the crystal and cannot be changed.The electrical signals generated by the crystal resonator are amplified and the resulting waveform is then sent to the output. This waveform will be a sinusoidal waveform with a frequency that is very close to the crystal\'s characteristic frequency. The device is typically designed to have a low jitter output, as well as a high level of accuracy and stability.

Conclusion

The ASTMHTA-20.000MHZ-XC-E oscillator is a highly stable and accurate oscillator that is suitable for a variety of applications. It utilizes a quartz crystal resonator to generate a precise frequency waveform of up to 20MHz. The oscillator is typically used for precision timekeeping applications such as clocks, watches, radio receivers, and audio equipment, as well as frequency reference signals in laboratory and communication equipment.
