Oscillators often referred to simply as “generators” are circuit components capable of producing an oscillating waveform. SIT9120AI-2D2-XXE106.250000X is one of these oscillators, the application field and working principle of it will be explained in the following.

Application Field

SIT9120AI-2D2-XXE106.250000X is a pair of RF oscillators with an adjustable frequency range from 10MHz to 1.025GHz. These oscillators have a wide range of applications, including use as a local oscillator in TV broadcast frequency synthesis, GPS tracking applications, and use in radar systems for signal modulation. This kinds of oscillator is used extensively in commercial and military applications due to its low cost and high performance.

Working Principle

The SIT9120AI-2D2-XXE106.250000X oscillator is based on the Pierce generated type oscillator. A Pierce generated type oscillator is a type of oscillator circuit that uses an amplifier in negative feedback with capacitive coupling to generate a sinusoidal signal. This type of circuit has the advantages of low harmonic distortion, low phase noise, and low power consumption compared to other circuits. In a Pierce generated type oscillator, a voltage controlled oscillator (VCO) is used to produce an alternating current signal whose frequency can be controlled by an external control voltage. The VCO signal is then passed through an amplifier in a negative feedback configuration to modify the amplitude of the signal in order to generate a sinusoidal waveform.

The SIT9120AI-2D2-XXE106.250000X oscillator is also known as a Pierce type oscillator because it uses a modified Pierce circuit cycle configuration to achieve the desired output frequency. The oscillator is designed so that the frequency of the generated signal is determined by three parameters: the oscillator’s supply voltage, the oscillator’s output frequency, and the oscillator’s loading capacitance. These parameters are adjustable to allow the frequency of the generated signal to be adjusted. Additionally, the oscillator has a temperature stability of ±10ppm, which is suitable for RF applications.

Conclusion

As a conclusion, SIT9120AI-2D2-XXE106.250000X is an excellent choice of oscillator for many RF applications. By using a modified Pierce generated type oscillator circuit, this oscillator achieves a low harmonic distortion, low phase noise, and low power consumption, while also having a wide adjustable frequency range and temperature stability. As such, it is an ideal option for many commercial and military applications.
