Working Principle

The DSC1121CI2-125.0000T is a voltage controlled oscillator (VCO) that works by generating an output frequency that is proportional to an applied voltage. This voltage is applied to the VCO’s input stage, which consists of a frequency-selective amplifier and a resonator. The resonator provides the oscillator with a frequency-dependent feedback loop, which is what allows it to maintain a stable output frequency underneath varying environmental conditions.

The frequency of the oscillator is determined by two factors: the frequency-dependent amplifications of the amplifier and the natural resonance frequency of the resonator. Both of these components must be precisely tuned to ensure that the oscillator produces an accurate output frequency. This can be done by adjusting the supply voltage of the amplifier or by manipulating the resonator using an external voltage variable resistor (VVR).

In addition to the amplifier and the resonator, the DSC1121CI2-125.0000T utilizes a high output power amplifier to boost the signal output, allowing it to drive a wide variety of devices. The power amplifier also helps to reduce distortion levels in the signal, resulting in a cleaner output.

Conclusion

The DSC1121CI2-125.0000T is a highly reliable precision oscillator. Its combination of size, power consumption and features make it an ideal choice for a wide range of applications. It is a voltage controlled oscillator that works by generating an output frequency that is proportional to an applied voltage, using an amplifier and a resonator. It also utilizes a high output power amplifier to ensure minimal distortion in the output signal.
