Oscillators

The SIT8208AC-G2-25S-33.333300X is a type of oscillator. Oscillators are electronic circuits that generate a repetitive output in the form of a periodic waveform. Oscillators are used in a variety of applications to generate signals at a desired frequency, such as in timing and control circuits.

Application Field

The SIT8208AC-G2-25S-33.333300X oscillator is specifically designed for Frequency Synthesis applications. This oscillator can be used as part of a frequency synthesizer to generate signals of a variety of frequencies, permitting the transmission or reception of multiple radio frequency channels. It can also be used in modem systems, microwave systems, and cellular base stations.

Working Principle

The SIT8208AC-G2-25S-33.333300X oscillator features both a reference oscillator circuit and a voltage-controlled oscillator (VCO) circuit, as well as a feedback circuit that converts the VCO frequency into a voltage that is used to control the VCO frequency. The reference oscillator is designed to generate signals of a pre-defined and stable frequency. The voltage-controlled oscillator is designed to generate signals of a frequency that is dependent on the voltage applied to it. The feedback circuit is designed to convert the VCO frequency into a voltage that is used to control the VCO frequency, thus maintaining the desired frequency.

The reference oscillator is a crystal oscillator with a fixed oscillation frequency. The voltage-controlled oscillator is designed with an amplifier and a variable capacitor bank. When voltages are applied to either side of the capacitor bank, the capacitance changes and thus alters the frequency of the oscillator. The output of the VCO is then fed back to the control input of the VCO, which adjusts the oscillator frequency to the desired frequency.

Conclusion

The SIT8208AC-G2-25S-33.333300X oscillator is an ideal choice for applications requiring precise frequency synthesis due to its combination of reference oscillator and VCO circuitry, as well as its feedback circuit. It is well suited for use in a variety of applications such as modem systems, microwave systems, and cellular base stations.
