SIT8209AI-GF-28S-106.250000T Working Principle

The oscillator is based on the PLL circuit and is based on a robust analog circuit. The frequency is fixed by an external crystal oscillator. The external input frequency multiplied by the loop filter and phase comparator of the PLL is generated. The output of the voltage controlled oscillator (VCO) is applied to the loop filter and phase comparator as feedback. As the output of VCO adjusts to the input frequency, the output of the loop filter stabilizes and the VCO output frequency locks.

The PLL technology used in the oscillator is a wide-range frequency, including both wide-band and narrow-band output. The oscillator circuit of SIT8209AI-GF-28S-106.250000T has a wide input frequency range, and the frequency resolution of 0.00625 MHz. The standby current consumption of the oscillator circuit is relatively low, which is only 6mA, which greatly reduces the power consumption of the package.
