Oscillators - SIT9120AC-1D3-33E161.132800Y application field and working principleOscillators are components used to generate electrical signals. The oscillator produces a signal output, which can be the same frequency as the input or it can be an entirely different type of signal. In electronic and electrical engineering, an oscillator is an electronic circuit used to represent a repetitive and time-varying signal. It has many uses and functions such as providing a clock signal for digital logic; they are also used in electronics to produce a range of frequencies that are useful in analog radio transmitters, other wireless communications systems, electro-mechanical systems such as clocks, and oscilloscope time bases.A type of oscillator, or oscillating circuit, that has become very popular with OEMs (original equipment manufacturers) is the SIT9120AC-1D3-33E161.132800Y oscillator. This is a Voltage Controlled Crystal Oscillator (VCXO) that operates within a band that is tuneable and also has excellent phase noise performance.This oscillator has many applications, including high speed data transmission in wireless communications, GPS (Global Position System) based applications and in hardware encryption systems. It is designed for time-critical applications, which require low jitter, and the accuracy and stability, as well as the repeatability of the oscillations, that are determined by a crystal oscillator that has integrated compensation-steering features.The SIT9120AC-1D3-33E161.132800Y oscillator has a frequency range of 28.8 to 131.13 MHz and a frequency accuracy of up to ±10 ppm over the full operating temperature range. It features a low phase noise of -184 dBc/Hz at 100 kHz offset and a wide range of frequency ratios.The working principle of the oscillator is based on the production of an alternating electrical signal. It consists of two main parts: an electrical circuit and a crystal. The electrical circuit produces a repetitive in-phase signal, while the crystal filters this signal by converting it from a sine wave to square wave and then back to a sine wave. This creates a stable frequency signal that is then amplified and sent through output connections.The SIT9120AC-1D3-33E161.132800Y oscillator has several key advantages, including: a low total phase noise; a high level of output frequency stability; a narrow range of frequencies; and a minimal temperature drift. The oscillator also has a low input voltage sensitivity and is able to meet the most stringent EMI (electromagnetic interference) and noise-coupling requirements.In summary, the programmable and highly accurate SIT9120AC-1D3-33E161.132800Y voltage controlled crystal oscillator is an invaluable and reliable electronics component for use in various electronic products, and is particularly useful for applications that require a stable and reliable signal, such as wireless communications and GPS systems. Its ability to output a range of specific frequencies with a high degree of accuracy and stability makes it a perfect choice for many electronics applications.
