Oscillators

Oscillators are a class of electronic circuit devices used for controlling and sustaining electrical frequency and oscillation in electrical circuits. Oscillators are used in applications such as regulating the frequency of a signal, and generating various waveforms for communications, video, computing, and audio systems. The SIT3808AC-D2-33NH-28.060000T component is an example of an oscillator, and this article will explore its application field and working principle.

Application Field

The SIT3808AC-D2-33NH-28.060000T component is an ultra-low power, temperature-controlled oscillator (TXCO) with a nominal output frequency of 28.06MHz. This device is designed to output a highly precise and stable frequency signal with extremely low power consumption. This TXCO component is ideally suited for applications such as: portable and handheld devices, mobile phones, digital cameras, telecom infrastructure, consumer and personal media players and other portable audio products.

The SIT3808AC-D2-33NH-28.060000T TXCO also has features like extremely low start-up time, low phase noise, an ultra-low power mode, no external components required, and no external tuning required. These features make it a great fit for battery-powered consumer electronics and audio applications, as well as telecom and datacom applications.

Working Principle

The SIT3808AC-D2-33NH-28.060000T TXCO operates by generating a precise frequency waveform from a quartz crystal. This oscillator operates on the principle of a Pierce oscillator, which uses two transistor stages to generate a high-stability and low jitter clock signal. First, a crystal is electrically connected between the base and collector of an NPN transistor. The crystal then produces a frequency waveform that acts as an input signal to the transistor\'s base.

In the second stage, the junction of the two transistors is connected to a feedback network consisting of a series of circuit elements. This network has the ability to alter its operation frequency slightly so as to compensate for changes in the load, temperature and frequency range of the oscillator. This is done by altering the magnitude of the current in the feedback path, which shifts the voltage at the base of the transistor, and consequently the frequency of the oscillator.

In addition to the Pierce oscillator configuration, the SIT3808AC-D2-33NH-28.060000T TXCO also features a PLL (phase locked loop) circuit which increases the stability of the signal. The PLL circuit actively detects any changes in frequency and automatically adjusts the oscillator\'s output frequency in order to maintain a precise output signal.

Overall, the SIT3808AC-D2-33NH-28.060000T oscillator component is an ideal solution for a variety of applications in consumer electronics, telecom and datacom, and other audio or video applications. Its features include precise frequency accuracy, ultra-low power and temperature-controlled operation, and advanced PLL technology for improved stability. With its ultra-low power operation, this device is an ideal solution for battery-powered electronic devices.
