Its low phase noise and high frequency stability make it suitable for use in high frequency signal generators, signal synthesizers, and frequency dividers. It is also suitable for use in military applications as its wide frequency range allows it to be used for radio communications. It can be used in a variety of other applications such as low noise sources in testing, metrology, medical equipment, and defense systems.
Working Principle
SIT3822AC-2B-25NG is an analog programmable oscillator. It consists of an external crystal oscillator and an internal circuitry consisting of a voltage-controlled oscillator (VCO). The VCO is the main element of the oscillator circuit and its frequency is determined by the external frequency control signal. The external frequency control signal determines the output frequency of the oscillator. The VCO also includes a voltage-controlled amplifier, which controls the amplitude of the output signal.
The frequency and amplitude of the output signal are adjusted by applying a digital signal to the programmable logic device (PLD). This signal configures the logic structure of the PLD, which in turn determines the exact frequency and amplitude of the signal generated. It also enables the programming of the signal parameters such as duty cycle and pulse width.
The output signal of the SIT3822AC-2B-25NG oscillator is then further filtered to remove any high frequency components, which can cause signal distortion. This signal is then amplified and used as the output of the oscillator.
Conclusion
SIT3822AC-2B-25NG is a versatile programmable oscillator that is capable of generating stable, accurate and wide frequency signals. Its frequency range covers a range from 1MHz to 25GHz. It is mainly used in microwave applications, low noise testing and metrology, military communications and other applications. The oscillator is also easy to program, as its output signal parameters can be adjusted by applying a digital signal to the programmable logic device.
