What is an Oscillator

An oscillator is a device that oscillates, or vibrates, continuously. Oscillators are used in a variety of applications such as electronic circuit design, electronic clock generation, computer-aided design, and communications technology. In order to understand the purpose of an oscillator, it is necessary to understand the concept of AC. AC, or alternating current, is an electrical current with periodic reversals in the polarity of its waveform. Oscillators generate AC, and they can also be used to modify or filter AC signals.

SIT9120AI-1CF-25E148.500000T Application Field and Working Principle

The SIT9120AI-1CF-25E148.500000T is a quartz oscillator module used in many electronic products. It is a high-quality, low-power, and low-phase noise product, suitable for resonators in voltage-controlled crystal oscillators (VCXOs), temperature-compensated crystal oscillators (TCXOs), and precision clock generators. The SIT9120AI-1CF-25E148.500000T operates at 9.12MHz and offers excellent phase control, low voltage drift, and tight frequency stability.The SIT9120AI-1CF-25E148.500000T can be used in a variety of applications, such as clocks and timers, frequency synthesisers, data conversion, and video stability. It is a reliable and low-jitter solution for a wide range of designs. The device features an inertial compensation technology, which helps mitigate temperature-induced drift. This compensates for slow frequency changes due to temperature fluctuations, ensuring that the specified frequency remains stable. The device is highly integrated and requires fewer external components for operation.The working principle behind the SIT9120AI-1CF-25E148.500000T is simple. A quartz crystal is mounted in a chamber called a resonator that vibrates at a predetermined frequency. A driver circuit begins to oscillate when voltage is applied to the resonator. This oscillation is then amplified and shaped, and sent out the output pin. The resonator\'s frequency can be adjusted using the external voltage control pin. The device is also temperature-compensated, meaning that its frequency will remain stable over varying temperatures.
