Applications

SG3225EAN 200.000000M-KJGA3 oscillator is ideal for applications used in high speed radio communication systems, including point-to-point, point-to-multipoint, Bluetooth, and Wi-Fi systems, as well as cellular, LTE/LTE-A, UMTS, and CDMA networks.

Working Principle

The SG3225EAN 200.000000M-KJGA3 oscillator operates by converting a low frequency voltage control signal to a high frequency signal at the output. The voltage signal is applied to the Control Terminal of the oscillator and a feedback loop is created with the capacitor and resistor network inside the oscillator. When the voltage applied to the control terminal reaches a certain value, a stable pulse is generated and this is amplified and fed back to the input to create an oscillating signal.

The frequency of the output is primarily determined by the external components such as inductors, capacitors and resistors. The frequency of the oscillator can be changed by changing the external components or by applying a different voltage to the control terminal. This allows the frequency to be tuned and kept within a certain tolerance.

Conclusion

The SG3225EAN 200.000000M-KJGA3 oscillator is a suitable solution for applications requiring frequency synthesis and clock generation, offering a wide range of operating frequency from 200MHz to 2.6GHz. The device offers a wide range voltage control for frequency, low total harmonic distortion, and is suitable for a variety of applications such as point-to-point, point-to-multipoint, Bluetooth, and Wi-Fi systems, as well as cellular, LTE/LTE-A, UMTS, and CDMA networks.
