Additionally, SIT9120AI-2D3-25E166.666000Y oscillator is also used in wireless standards like Wi-Fi, Bluetooth, ZigBee and GSM for the same purpose.

The working principle of SIT9120AI-2D3-25E166.666000Y oscillator revolves around the synchronization of multiple PLL blocks. When the voltage input is given, the PLL blocks generate a pulse width modulation (PWM) signal to control the timing, turning, frequency and voltage of the output. The electrical characteristics and frequency are determined by the feedback loop, which comprises of voltage-controlled oscillator (VCO), phase detectors, low pass filters, and charge pumps.

The PLL blocks, in conjunction with the other components, keeps the output\'s frequency within a specific range and at a particular value. When deployed, the oscillator automatically trims and tunes itself to acquire the proper frequency values. Moreover, it can detect sudden variations in the supply voltage, preventing undue wear and tear of the components.

The SIT9120AI-2D3-25E166.666000Y oscillator also incorporates a spread spectrum frequency modulation (SSFM) scheme in order to further reduce the jitter noise and minimize the effect of electromagnetic interference (EMI). This reduces the amount of power dissipated while switching during the oscillation of the frequency, resulting in an efficient and accurate operation.
