Working Principle：

The SIT9005ACA2H-25SJ is based on the PLL (Phase Lock Loop) principle. This oscillator contains two different sections namely the reference circuit and the output circuit. The reference circuit is made up of a capacitor, an adjustable resistor and a voltage controlled oscillator (VCO). The voltage controlled oscillator is used to generate a signal of a specific frequency. The output circuit is made up of an amplifier, a frequency divider, and a phase detector. The frequency divider is used to divide the frequency of the VCO to obtain the output signal of the desired frequency.

The VCO signal is compared to the reference signal at the phase detector and the difference between the two signals is used to control the output frequency. The amplifier is used to increase the output signal strength and the frequency divider reduces the frequency of the VCO signal to the desired frequency. The output of the PLL is a steady signal at a precise frequency, which is stable and reliable.

Conclusion：

The SIT9005ACA2H-25SJ is a programmable oscillator that is used to generate signals at a precise and stable frequency. It has wide range of applications in various industrial, scientific and commercial operations. The principle of the PLL is used in this oscillator to ensure accuracy and reliability of the output signal. The SIT9005ACA2H-25SJ is a reliable and cost effective programmable oscillator for frequency control.
