Oscillators refer to devices that generate an output waveform with a certain frequency and amplitude. Common oscillator types include phase-locked loops (PLLs), voltage-controlled oscillators (VCOs), crystal oscillators (XO), and SIT8256AC-81-25S-156.257812Y oscillators. They are usually used in applications such as frequency synthesizers, clocks, and timers.The SIT8256AC-81-25S-156.257812Y oscillator is a quartz crystal oscillator (QXO) that subdivides the 25MHz reference frequency generated by a monitoring circuit into a required output frequency. It utilizes a proprietary and reliable oscillation structure with low phase noise performance, allowing for a high level of automation when used in today\'s frequency synthesizers.This oscillator operates at 0°C to 70°C temperatures, operates at a supply voltage of 3.3V and 3.8V, has an operating frequency range of 25MHz to 800MHz, and is packaged in a ceramic surface mount package. It has a superior pull range of ±50ppm. This oscillator also has a variety of features, such as wide frequency range operation, low jitter, low phase noise, and wide supply voltage operation.The main applications of SIT8256AC-81-25S-156.257812Y oscillator are in frequency synthesizers, telecom, Wi-Fi, data communications, military/aerospace equipment, medical equipment, GPS systems, KVM switches, Bluetooth, and consumer electronics.When used in frequency synthesizers, the oscillator generates a reference signal that is later used to generate the desired output frequency. This oscillator contains a quartz crystal that resonates at a certain frequency and helps to stabilize the oscillation signal. This quartz is held at the center in a housing by a pair of electrodes and a gap filled with air.When a voltage is applied to the electrodes, the quartz vibrates and creates an alternating electric field. This alternating electric field creates a voltage that is fed back into the oscillator, creating a feedback loop, and the oscillation signal. This signal can then be output from the oscillator at a range of frequencies up to 800MHz.The oscillation signal is very important to the operation of the frequency synthesizer. The frequency synthesizer uses the oscillation signal to generate the desired output frequency. The oscillation signal is also used to measure the exact frequency of the output frequency.In conclusion, the SIT8256AC-81-25S-156.257812Y oscillator is a quartz crystal oscillator that is used for generating a reference signal for frequency synthesizers. It is designed to operate at temperatures from 0°C to 70°C, has an operating frequency range of 25MHz to 800MHz, and comes in a ceramic surface mount package. This oscillator also has features such as low phase noise, wide supply voltage operation, and a wide pull range of ±50ppm, making it ideal for frequency synthesizers and other telecom, Wi-Fi, data communications, and consumer electronics applications.
