Oscillators: M670-669.3266 Application Field and Working Principle

Oscillators are electrical circuits used to generate and control a steady and continuous frequency of alternating current (AC). This frequency can be as low or high as desired, and it helps in creating regular pulses for various purposes, such as controlling the operation of a clock or a motor. Oscillators of the type M670-669.3266 are mainly used to control the operation of airplanes, as they are designed with high stability and reliability.

Applications of M670-669.3266

The M670-669.3266 oscillator is a commonly used oscillator in many aviation systems. It is mainly used in controlling aircraft and their components. It is designed to work particularly with two systems, the Attitude Heading Reference System (AHRS) and the Autopilot Management System (AMP). Both of these systems are governing the movement, navigation, and orientation of the aircraft. The AHRS maintains the aircraft’s attitude, direction and velocity by referring to a global positioning system, while the AMP is used for maintain the aircraft’s altitude, speed, and increase or decrease the speed during the flight.

Because of its high reliability and stability, the M670-669.3266 is widely used in jet airplanes, turboprop and gliders, helping the pilots maintain constant signals and eliminating the need for manual adjustments. It can also be used properly in weather radar applications, where the output frequency is constant and provide stable signals over varying weather conditions.

Advantages of the M670-669.3266 Oscillator

The M670-669.3266 oscillator is designed to withstand high-shock and vibration environments, making it ideal for aircrafts’ components. It operates at -55 to 150 degrees Celsius, which is suitable for rigorous aviation operations. The system also has very low phase noise values and it features very high frequency stability, meaning it is able to maintain constant output signals even when the environmental conditions changes.

The M670-669.3266 oscillator is also suitable for various power supplies. It is able to run off an AC power supply, although it is also available as a battery-backed up system, where a backup battery allows it to keep operating even if the main power is cut off.

Working Principle of the M670-669.3266 Oscillator

The M670-669.3266 oscillator is a combination of voltage-controlled oscillator and a phase-lock loop. It features a voltage-controlled crystal oscillator (VCXO) with a temperature-sensed resonator. The VCXO is connected to a temperature-sensed quartz crystal resonator, with the resonator’s frequency adjustment depending upon temperature and frequency variations. This ensures that the frequency of the oscillator’s output is constant and its accuracy stays within the required range.

The temperature-sensed resonator is also connected to an amplifier and a low noise amplifier. The amplifier amplifies the output signal from the VCXO and increases it to the required level. The low noise amplifier then eliminates any noise introduced through the process, ensuring the signal that is generated is clean and stable.

Conclusion

The M670-669.3266 oscillator is an excellent choice for aircraft control due to its high reliability and stability. It has a low phase noise and high frequency stability, meaning it is able to maintain constant output signals even when the environmental conditions changes. The combination of its voltage-controlled oscillator and a phase-lock loop also ensures the signal that is generated is clean and stable.
