Working Principle

At its most basic level, an oscillator is an electrical circuit capable of producing an alternating current signal with a constant amplitude and frequency. The SIT8208AC-2F-33E-12.800000X oscillator is an example of an oscillator that uses a digital phase-locked-loop (PLL) to generate an output signal. The main components of a digital PLL include a phase frequency detector (PFD), a voltage-controlled oscillator (VCO), and a charge pump.

The PFD is used to compare the frequencies of the input signal and the output signal. When the two frequencies are not equal, the PFD sends out control signals that change the frequency of the VCO. The voltage-controlled oscillator is then used to create the output signal with the desired frequency. The charge pump is used to provide the necessary voltage to control the VCO.

In addition to using the PLL, the SIT8208AC-2F-33E-12.800000X oscillator also features a temperature-controlled oscillator (TCXO) to ensure optimal frequency stability under changing conditions. The TCXO provides a small temperature coefficient of frequency so that the output of the oscillator is unaffected by fluctuations in temperature.

The SIT8208AC-2F-33E-12.800000X oscillator is a robust and reliable component that is used in a variety of applications. Its digital PLL makes it ideal for precise frequency control in frequency synthesizer and radio receiver circuits. With its temperature-controlled oscillator, it is also able to maintain a constant output frequency under varying conditions.
