Oscillators

Oscillators are control devices that have the ability to maintain an output signal and produce a steady-state waveform of desired parameters. Oscillation, which is an important attribute of oscillators, enables them to generate a series of signals at relatively constant intervals and can be classified into various types depending on different requirements. One of them is SIT8208AC-22-18E-32.768000Y oscillator.

SIT8208AC-22-18E-32.768000Y oscillator is designed for general-purpose applications such as clock and timing control, low EMI and EMC. It is suitable for both commercial and industrial environments. It is especially suitable for consumer electronics as it has low power consumption, good temperature stability and high stability over frequency. It is often used in embedded systems, microcontrollers, hard disk controllers, drives, digital audio devices, digital video players and mobile phones.

Working Principle of SIT8208AC-22-18E-32.768000Y Oscillator

The SIT8208AC-22-18E-32.768000Y oscillator generates a clock signal of a specified frequency by using a quartz crystal as an oscillator element. The quartz crystal consists of a tuning fork shaped quartz piezoelectric crystal and two electrodes. When the quartz is vibrated, it will generate an alternating ac voltage across the two electrodes, and the frequency is determined by the shape and physical parameters of the crystal. This generated ac voltage is smoothed by a high-stability electronic circuit, thus providing a steady and accurate frequency for the oscillator.

In the SIT8208AC-22-18E-32.768000Y oscillator, a quartz crystal is placed between two electrodes in a metal can. The quartz crystal resonance is driven by the external voltage input, and its specific frequency is determined by the manufacturer in accordance with the requirements of customers. Then the resonance circuit is composed of a resonant capacitor and an inductor, and the output signal is generated from the resonance circuit. This output signal is temperature compensated, and its jitter and frequency stability are also guaranteed, so that good performance can be achieved in most applications.
