Working Principle of SIT9003AI-2-25EO

The SIT9003AI-2-25EO utilizes a temperature compensated oscillator (TCXO) to achieve the desired output frequency. The TCXO uses a dual PLL loop to allow for precise control of the output frequency. The loop consists of two voltage controlled oscillators (VCOs), one of which is used to produce the desired output frequency, while the other is used to provide an error signal to the loop. An algorithm is then used to adapt the VCO frequency to match the desired output frequency.

In addition to the TCXO, the SIT9003AI-2-25EO utilizes several other components including an oscillator amplifier, a differentiator, a voltage controlled amplifier (VCA), a digital-to-analog converter (DAC), and a control logic circuit. The oscillator amplifier helps to generate the proper frequency output, while the VCA adjusts the frequency in order to maintain accurate control. The DAC then translates the digital instructions from the algorithm into analog signals, which are used to control the output frequency.

Finally, the control logic circuit allows the oscillator to be programmed with various frequency settings. These settings can be easily changed either manually or through an external controller. This flexibility makes the SIT9003AI-2-25EO an ideal choice for applications with changing requirements.

Conclusion

The SIT9003AI-2-25EO is a programmable oscillator designed for use in communication, space and industry applications. Its TCXO circuit and other components allow for precise control of the output frequency, and its power saving capabilities make it well suited for applications with power limitations. Furthermore, its control logic circuit allows for easy programming of the oscillator, making it an ideal choice for applications with changing requirements. Therefore, the SIT9003AI-2-25EO is an excellent choice for radio receivers, scan receivers, and other frequency conversion systems.
