Oscillators: SIT8208AC-82-28S-8.192000Y application field and working principle

Oscillators generally refer to electronic components that can generate periodic signals. Its main function is to provide mechanical transmission signals, produce pulse or sinusoidal signals, and provide stable frequency reference signals for the operation of rest of the circuits. Oscillators are widely used in a number of areas such as communications, computer systems, and machine controllers. The Oscillator application field and working principle of SIT8208AC-82-28S-8.192000Y is described in detail below.

Applications for SIT8208AC-82-28S-8.192000Y Oscillators

SIT8208AC-82-28S-8.192000Y Oscillator belongs to the high stable and high-frequency oscillator developed by the company. Its typical application contains but not limited to the following areas.

Computer systems

Computer system is one of the most commonly used systems areas which need an oscillator to function properly. The CPU in a computer system depends heavily on a stable oscillator. The SIT8208AC-82-28S-8.192000Y oscillator adopts Flexible Oscillator Architecture (FOA), which supports store-and-forward PLL structure, with input clock level from 0V to 3.3V. This could provide a stable reference signal to the CPU to make sure it runs at the defined speed and parameters.

Communication equipment

The oscillator is also an indispensable part in the communication systems. Whether it is a base station in a radio communication system or a booth in a telephone communication system needs an oscillator to coordinate operations. The SIT8208AC-82-28S-8.192000Y Oscillator has the characteristics of wide operating temperature, small size and high stability. It is an ideal choice for communication application areas.

Portable product

In order for a “portable” product to be able to maintain the same performance no matter where it is being used, a high-stability oscillator is also needed. The SIT8208AC-82-28S-8.192000Y Oscillator is specially designed to meet the needs of portable products such as Personal Digital Assistant (PDA), Mobile Phone and Digital Camera. Its excellent performance greatly improve the system stability and reliability.

The Working Principle of SIT8208AC-82-28S-8.192000Y Oscillator

The working principle of the SIT8208AC-82-28S-8.192000Y Oscillator is relatively simple. It works by amplifying a weak signal into a strong signal and then rectifying Half Wave Rectification or Full Wave Rectification to generate an oscillation wave of an accurate frequency.The basic structure of the oscillator contains an amplifier, filter and feedback circuit. There are two kinds of SIT8208AC-82-28S-8.192000Y Oscillator: negative feedback and positive feedback. These two oscillators are equal and share the same principle: the amplifier amplifies the input signal, and the filter attenuates the frequency of the signal so that only certain part of the signal will contain energy; and the feedback circuit completes the feedback, makes the signal being amplified again, so that the output signal will be an oscillation wave that frequency is exactly the frequency of the amplifier.

Conclusion

The SIT8208AC-82-28S-8.192000Y Oscillator is ideal for high-stability applications in the computer, communication and portable product fields. Its excellent performance and the simple working principle make it easier for it to be used in these fields. Its wide operating temperature range, small size and high stability make it an ideal choice for all these application areas.
