Oscillators

An oscillator is an electronic circuit that produces a repetitive signal. It is an electronic device used to maintain a stable frequency or generate a signal in communication systems. Oscillators are especially important for radio applications as they are used to generate the radio frequency signals used in transmitting and receiving radio communication. One example of oscillator is the 535FB106M250DGR.

Application Field

The 535FB106M250DGR oscillator is a standard type of active crystal oscillator. It is mainly used in local area networks (LANs), Wi-Fi, satellite systems, microwave systems, and digital radio communication. Its application field also includes data processing systems, broadband signal application, and industrial automation for providing accurate frequency references for processors or controllers. It is especially suitable for high-speed data processing and because of its low power consumption.

Working Principle

The basic working principle of the 535FB106M250DGR is based on the generation of a quartz crystal oscillator signal generated by applying a high frequency electric signal to the oscillator. This oscillator signal is then amplified and the PLL (Phase Locked Loop) is used to maintain the desired frequency. The oscillator output can be seen as a triangle wave, which is then applied to the RF (radio frequency) amplifier circuit to create a sinusoidal waveform. The output of this amplifier circuit is the actual radio frequency signal.

The 535FB106M250DGR is composed of a quartz crystal tank circuit with an amplifier circuit connected to it. The oscillation of the tank circuit is influenced by the electric field applied to the quartz crystal, thus the frequency can be precisely adjusted by the electric field frequency. The PLL will detect the oscillation frequency and compare it to the reference frequency and will then adjust the driving voltage applied to the quartz crystal to maintain the reference frequency.

In addition, the amplifier circuit is used to boost the amplitude of the oscillator output. The output of the amplifier is then processed by an band pass filter to restrict the frequency range and shape the waveform of the output signal. Finally, the PLL will monitor and adjust the driving voltage according to the detected frequency.

Conclusion

The 535FB106M250DGR is an oscillator that is used in many applications such as LANs, Wi-Fi, satellite systems, and digital radio communication. The working principle of this oscillator is based on the generation of a quartz crystal oscillator signal, which is then amplified and the PLL (Phase Locked Loop) is used to maintain the desired frequency. The output of this amplifier circuit is then processed by an band pass filter to restrict the frequency range and shape the waveform of the output signal.
