Oscillators

SIT9121AI-1D1-33E156.269531Y is an oscillator type electronic component. It has wide application in the circuit system. Here is an introduction of its application field and working principle.

Application Field

SIT9121AI-1D1-33E156.269531Y can be applied in many fields that need precise frequency generating and time controlling, including electrical appliances, robots, metering instruments, medical device, consumer electronics and so on.

For example, it can be used in medical imaging equipment such as scanning ultrasound machine, it will generate precise frequency signal to control the scan beam generation; it can be used in the power grid for frequency generating and signal control.

Working Principle

SIT9121AI-1D1-33E156.269531Y working principle is based on negative induction. It provides a certain level of frequency output, and maintains stability from the effect of feedback. The oscillator circuit is composed of a mixer, an amplifying device and a resonant circuit. When the feedback circuit that connected the output and input is operating, it is able to repeat the output voltage signal of the resonant circuit. This process is called the negative induction, which is used to maintain a certain level of frequency output, and to make the output of the oscillator stable and precise.

SIT9121AI-1D1-33E156.269531Y can work in two different operation modes, one is using the amplitude-controlled voltage of the voltage-controlled oscillator to control the frequency output, and the other is using temperature compensation, which means that the output frequency is maintained in a stable state when the ambient temperature changes.

Conclusion

SIT9121AI-1D1-33E156.269531Y is a oscillator type electronic component with a wide range of application. It can operate in two modes, amplitude-controlled and temperature-compensated. Its working principle is based on negative induction, which can provide the device with stable and precise frequency output.
