Oscillators are components which generate recurrent alternating waveforms that are used as timing signals or continuously oscillate without being externally triggered. These electronic components feature properties that make them suitable for many modern applications, such as radio wave generation. MXO45-2C-27M0000 oscillators, in particular, are microprocessor-controlled frequency generators, developed to meet the needs of precision timing applications. This article will explain the fields of application and working principle for these oscillators.

Application Fields

The MXO45-2C-27M0000 oscillator is a high-precision frequency generator, with frequency stability of +/- 10 Parts-per-Million (PPM) over -40 to 125 C. This precision makes them suitable for a variety of applications, such as clock circuitry, signal processing, and microprocessor control. They are commonly used in communication systems, medical equipment, satellites, telecommunications, microcontrollers, test and measurement equipment, broadcasting, aviation, automobile, navigation and tracking systems.

Further, these oscillators feature an extended temperature range (-55 to +125 C). This extended range allows the device to function in diverse environmental conditions, from factory floors to the chill of space. Additionally, these oscillators offer additional control features such as output tri-state enable, output logic selection, and a bidirectional frequency adjust signal.

Working Principle

The MXO45-2C-27M0000 oscillator is a microprocessor-controlled frequency generator and operates based on a two-stage frequency synthesizer architecture. It combines a phase-locked-loop (PLL) and voltage controlled oscillator (VCO).

The first stage of the oscillator is the PLL, which compares the signal from an external reference frequency with its own output signal. The PLL amplifies any differences in the signals and uses this information to adjust the control voltage which is sent to the VCO, which then produce the frequencies that are needed for the given application. The output frequencies can then be adjusted further by the control signals which are sent back to the PLL.

The oscillators also feature a start-up circuit which allows the device to quickly and accurately measure and store the frequency and voltage of the given reference signal and set up the oscillator. This start-up circuit improves the accuracy and reliability of the oscillator and ensures that it is able to accurately produce the frequency needed for the given application.

Conclusion

The MXO45-2C-27M0000 oscillator is a high precision frequency generator designed to meet the precision timing requirements found in many modern applications. Its two-stage frequency synthesizer architecture, along with its extended temperature range, makes it suitable for a variety of applications such as communication systems, medical equipment, and microprocessor control. With these features, these oscillators are sure to remain a reliable and stable source of timing for many years to come.
