Working Principle of SIT8920BM-72-33E-32.000000G

SIT8920BM-72-33E-32.000000G consists of three main components: the crystal oscillator, the frequency divider/modulator, and the control logic. The crystal oscillator, typically a quartz crystal, is the core of the oscillator. It acts as a resonator, based on the principle that when a quartz crystal is supplied a certain amount of energy, it will produce a very accurate frequency. The output of the crystal oscillator is then divided down by the frequency divider/modulator, and the output of this device is then used by the control logic to produce the desired frequency. The control logic in this oscillator is a very important component. It provides programmability to the oscillator, enabling it to be easily adjusted to a specific frequency. In addition, the control logic also allows the oscillator to produce a fixed frequency or a swept frequency. The swept frequency can be used to test the performance of the oscillator.

Conclusion

In conclusion, SIT8920BM-72-33E-32.000000G is a SiT8920 oscillator that is used for a variety of telecom and RF applications. It is equipped with a high precision crystal oscillator, a frequency divider/ modulator, and a control logic. The control logic provides programmability and a swept frequency to the oscillator, making it suitable for highly demanding applications.
