Working Principle

The working principle of SIT8008BIA3-25E is based on the principle of phase-locked loop digital frequency synthesis. The phase-locked loop (PLL) consists of voltage-controlled oscillator (VCO), phase detector, integration circuit, low-pass filter and other components. The working principle of PLL is very simple. After the input signal of the phase detector is filtered by the low-pass filter, the control signal of the VCO can be realized by the phase detector and integration circuit. The phase difference between the input signal and the output signal of the VCO will be continuously adjusted by the control signals produced by phase detector and integration circuit to realize the frequency synthesis of PLL.

In addition to the working principle of PLL, different oscillator also need to consider additional operating parameters, including the oscillation mode, temperature range, frequency accuracy, power supply voltage and other relevant parameter settings. In general, SIT8008BIA3-25E selected ECL mode as the oscillator mode and integrated dual digital temperature compensation technology. It has a wide temperature range and excellent frequency accuracy. As long as the parameters are adjusted correctly, it can achieve excellent frequency control performance.

Conclusion

In summary, SIT8008BIA3-25E is a kind of programmable oscillator, which can be used in military equipment, industrial automation control, communication equipment, computer motherboards, and other equipment. The working principle of SIT8008BIA3-25E is based on the principle of phase-locked loop digital frequency synthesis, combined with the selection of ECL mode and integrated dual digital temperature compensation technology.
