Oscillators

Oscillators are electronic circuits which generate repetitive signals. They are widely used in a variety of applications such as timekeeping, communication, signal processing and control systems. One of the most commonly used oscillators is the SIT1602BI-12-25N-74.176000D.

Application Field

One of the main applications for this oscillator is in radio frequency (RF) systems. It can be used to generate high-frequency signals, such as those used in Frequency Modulation (FM) and Phase Locked Loop (PLL) systems. It is also suitable for digital applications such as mobile phones and portable audio systems. This oscillator can also be used in analog applications as it has low jitter and good frequency stability.

Working Principle

The SIT1602BI-12-25N-74.176000D oscillator is based on a Digital Phase Locked Loop (DPLL) circuit which is made up of a Voltage Controlled Oscillator (VCO), a phase detector, and a low-pass filter. The DPLL circuit operates by comparing the phase of the output of the oscillator to the reference clock. If there is a discrepancy, the phase detector generates a control voltage that is used to adjust the frequency. This adjustment of the frequency is what allows the circuit to maintain the desired frequency stability.

Conclusion

The SIT1602BI-12-25N-74.176000D oscillator is a versatile and reliable component which is suitable for a broad range of electronic and digital applications. Its Digital Phase Locked Loop (DPLL) circuit allows it to maintain a steady frequency, making it ideal for frequency modulation and phase locked loop systems.
