Oscillators are commonly used in many electrical circuits. They produce a periodic electrical signal, and are used for various applications. Most kinds of oscillators are powered by alternating current (AC) or direct current (DC) power supply. The 590PB27M0000DG is an example of an oscillator.

Application Field of 590PB27M0000DG

The 590PB27M0000DG oscillator is a high-precision oscillator, and it is designed for many kinds of radio navigation equipment, such as loran, Loran-C, and Omega navigation systems. It enables the radio navigation systems to receive precise timing information from GPS satellites. Furthermore, it is also suitable for quasi-continuous wave (QCW) and pulse operation. It is especially helpful with its impressive I2C synchronization interface, which is very important for the absolute timing alignment of radio navigation systems.

Working Principle of 590PB27M0000DG

The 590PB27M0000DG is based on the quartz crystal as the timing reference, which makes it an electro-mechanical oscillator that produces a precise output frequency. Within the oscillator, an amplifier is used to increase the impedance of the quartz crystal for it to oscillate correctly. Generally, the amplifier consists of an amplifier stage and a feedback stage, where the feedback stage determines the influence factor of the oscillation output frequency. In order to get a precise output frequency, a highly stable and temperature-insensitive resonator is required, and the quartz crystal fits this purpose perfectly. The quartz crystal operates based on the piezoelectric effect, which is the key of the oscillator’s function. For this effect, when an electrical charge is applied to the quartz crystal, the quartz crystal vibrates/oscillates at a certain frequency. This frequency can be determined by the constants of the quartz crystal. That is, if the constants are known, you can then calculate the frequency at which the quartz crystal will vibrate. And the 590PB27M0000DG makes use of this principle to produce a precise output frequency.

Conclusion

The 590PB27M0000DG is an oscillator device primarily used in radio navigation systems. It works based on the piezoelectric effect of the quartz crystal, and features a high-precision and a highly stable output frequency. With its impressive I2C synchronization interface and other features, it is an ideal device for the absolute timing alignment of radio navigation systems.
