Oscillators: FN2500165 application field and working principle

Oscillators are circuits that generate repetitive signals. The FN2500165 oscillator is a low-cost, low-power oscillator integrated circuit (IC). It has an internal frequency setting circuit allowing frequencies from 2MHz to 150MHz to be generated.

Application field

The FN2500165 oscillator is used in a variety of applications, such as clock and data generation, radio frequency (RF) oscillation, signal analysis and timing tools in test systems. Integrated timing tools are used in embedded systems, monitoring equipment, motor controls and digital receivers.

It is also used for automotive multimedia systems, digital video and data communications, xDSL modems, frequency counter boards, multi-channel demodulators, digital still camera and in medical devices such as electrocardiography units.

Working Principle

The FN2500165 oscillator IC has an output frequency that is determined by a timing resistor and capacitor connected to pins 4 and 5 of the IC. This pin configuration is known as an RC oscillator. A voltage is applied across the capacitor and resistor. This creates a time delay to charge and discharge the capacitor. The oscillation frequency is calculated by the time taken to charge and discharge the capacitor, which is determined by the values of the capacitor and resistor. The oscillator generated frequency can be adjusted by altering these values.

The FN2500165 IC also has a temperature compensation feature. This allows the oscillator to maintain a steady output frequency regardless of changes in temperature, ensuring that a stable signal frequency is outputted. This makes it an ideal choice for applications such as HDTV and audio systems, medical instruments, military systems and other devices.

Conclusion

The FN2500165 low-cost, low-power oscillator IC is a robust and reliable choice for applications that require a regulated output frequency in a variety of settings. It is a versatile and easy to use oscillator that is suitable for many applications. By using temperature compensation, the oscillator can maintain consistent output frequencies regardless of environmental changes.
