Working Principle

SIT1602BI-11-18N-40.000000E oscillators employ a Phase Locked Loop (PLL) circuit. The PLL consists of an oscillator, a voltage- controlled oscillator, a loop filter, and a phase detector.The oscillator generates a continuous wave signal, which serves as a reference signal for the phase locked loop. The voltage-controlled oscillator utilizes the reference signal to generate a frequency signal, which is compared with the reference signal and adjusted by the phase detector.The phase detector compares the phase and frequency of the reference signal and the VCO signal, and then adjusts the parameters of the VCO until the two signals are in phase and have the same frequency. The loop filter then filters out any noise or ripple that may be present in the VCO signal, ensuring stable and reliable operation.

Conclusion

SIT1602BI-11-18N-40.000000E oscillators are used in a wide range of applications, such as cellular communications, test and measurement equipment, quartz crystal oscillators, and other applications that require tight frequency stability. These oscillators employ a Phase Locked Loop circuit, which enables them to maintain a stable and accurate frequency output.
