Oscillators are a type of electronic component that creates and maintains an oscillating electronic signal. They are widely used in a variety of applications, including health care, military and aerospace, consumer and automotive, communications, IT and networking, and industrial automation. The 520T25DA16M3690 is a frequency control oscillator (FCO) device from Ecliptek Corporation that offers features such as ultra-low current, low jitter or high frequency stability at very reasonable cost. In this article we will discuss the application fields and working principle of the 520T25DA16M3690.

Application Fields

The 520T25DA16M3690 is a very versatile FCO, and can be used in a variety of fields where low noise and high frequency stability are required. It can be used in TV and radio tuning circuits due to its low jitter and low noise, as well as frequency division circuits and frequency synthesis. In (consumer) automotive applications, the 520T25DA16M3690 can be used for systems such as ABS, brakes, engine management and LED lighting. Other fields of use include personal computers, cloud computing, data storage, medical imaging, surveillance and security.

Working Principle

The oscillator inside the 520T25DA16M3690 is an oscillator circuit with an active device, such as a transistor, and an R-C filter (made up of resistors and capacitors). When an electrical signal is input to the circuit, it begins to oscillate and produces an output signal. The output signal is then filtered through the R-C filter, resulting in a waveform of a certain frequency and amplitude. The frequency and amplitude of the oscillator can be controlled by adjusting the values of the components in the circuit (such as the resistors and capacitors).

The 520T25DA16M3690 uses an integrated circuit (IC) to make an oscillator, called a PLL (phase locked loop) oscillator. This type of oscillator has a reference circuit and a verification circuit. The reference circuit has its own oscillator, and the verification circuit follows the reference circuit’s output to compare and adjust its own frequency and amplitude. The comparison and adjustment are done continuously at high speed, and the generated output signal has very low jitter and is highly stable.

The 520T25DA16M3690 also includes other components, such as a voltage regulator and a temperature compensation circuit. The voltage regulator controls the voltage that is applied to the device, while the temperature compensation circuit ensures that changes in temperature do not affect the frequency or amplitude of the output signal.

Conclusion

The 520T25DA16M3690 is a frequency control oscillator that is suitable for a wide range of applications. It has low current consumption, low jitter and excellent frequency stability, making it an ideal choice for systems where frequency stability and low-noise operation is required. Its working principle is based on an oscillator circuit with an active device and an R-C filter, with other components such as a PLL oscillator, voltage regulator and temperature compensation circuit included to ensure it meets the system’s requirements.
