FN2500246 is a versatile oscillator which can be used in many applications to generate reference signals for systems. This oscillator contains two types of components, a Voltage Controlled Oscillator (VCO) and a Phase Locked Loop (PLL) fabricated in a single monolithic silicon chip package. As a result, the oscillator is capable of generating ultra-low jitter, high-frequency signals.

Application Field

FN2500246 oscillators have been used in a wide range of applications, such as communication systems, signal source generation, ultra-low-noise power supply regulation, clock generation, and frequency synthesis. The oscillator is also used in military and aerospace applications for ultra-precise timing and frequency stability. Furthermore, these oscillators are suitable for automotive and medical applications, as well as professional audio and broadcast systems.

Working Principle

FN2500246 oscillators are based on a simple principle - the phase-locked loop (PLL). The PLL consists of two main components, an oscillator and a control circuit. The oscillator produces a reference signal, which is then compared to an input signal. The control circuit adjusts the generated signal until it is in phase with the input signal. Once the oscillator and the PLL are locked together, the oscillator produces a consistently accurate output signal.

The oscillator in the FN2500246 is a voltage-controlled type. This means that the oscillator’s output frequency is determined by the control voltage applied to it. The voltage applied can be either a low or high voltage, depending on the desired output frequency. In addition to the voltage-controlled oscillator, the generator also contains a phase-frequency detector, and a number of other elements such as amplifiers, counters, dividers and comparators to ensure the oscillator operates accurately.

The output of the oscillator is typically sine, square, or triangle waves. This output is then fed through dividers, which divide the frequency of the output signal. The number of stages in the dividers and the division ratio determine the frequency of the output signal.

The output of the oscillator has a very low jitter, typically less than 10 picoseconds peak-to-peak. It also has a very high frequency stability, typically better than 1 ppm. Additionally, the oscillator can operate over a wide frequency range, from 25 MHz to 250 MHz.

In summary, FN2500246 oscillators are versatile and reliable signal generators that are suitable for many applications, such as communication systems, signal source generation, ultra-low-noise power supply regulation, clock generation, and frequency synthesis.
