Oscillators are used for the generation of repetitive signals with precise frequency or time period and can be potentially used as timing circuits. An oscillator usually converts a DC voltage supply into an AC signal, and the generated signal keeps oscillating between two margins for an indefinite time. SIT9120AC-1B3-25E166.666000D oscillator is a standard type in the oscillator field with high performance and wide applications.

This oscillator belongs to the category of quartz oscillators, which have high stability and accuracy as compared to other types of oscillators such as RC or LC oscillators. It is basically a quartz crystal resonator that includes oscillating reverse-biased transistors. The oscillator can be conditioned electronically to generate signal of specific frequency. This type of oscillator requires some additional hardware like capacitors, inductors and other elements for loading during the operation.

The frequency of oscillation generated by this SIT9120AC-1B3-25E166.666000D oscillator range from 1KHz to 25MHz and can also be configured to even higher frequencies. The output signal is also quite clean with close to zero distortion. Furthermore, it has a very low phase noise and hence it is widely used for frequency multipliers and modulators.

The working principle of the SIT9120AC-1B3-25E166.666000D oscillator is quite simple. It involves two stages - an oscillating stage and a frequency-determining stage. The oscillating stage consists of two transistors, the base-emitter junction of each transistor is reverse-biased. External circuitry such as a capacitor is connected in series with the oscillating transistors to form an oscillation loop. The resultant voltage across the transistors generates an oscillating signal between two extreme voltages. This signal is further amplified in the frequency-determining stage where the gain of the amplifier is directly proportional to the frequency of the signal.

The SIT9120AC-1B3-25E166.666000D oscillator is widely used in industrial, telecom and electronic field. Some applications include frequency modulation, communication systems, cellular phones, 3G/4G multi-mode networks, satellite and broadcast systems, clock generation in GPS systems, industrial machinery, embedded systems, consumer products, and many more. They are also used for test and measurement applications like frequency counter, signal generators, and spectrum analyzers.

The SIT9120AC-1B3-25E166.666000D oscillator is highly reliable due to its robust construction and low power consumption. It offers good immunity to environmental disturbances like temperature, pressure, electromagnetic radiation, and vibration. Its features like small size, low cost and increased performance have made it one of the most popular choices for many electronic, telecom and industrial applications.
