SIT9002AC-43H25DB working principle

The SIT9002AC-43H25DB programmable oscillator operates on a patented Phase Locked Loop circuit. This circuit locks a reference frequency from an external clock to an oscillator, resulting in a much narrower frequency range than can be achieved through frequency synthesis circuits. The reference frequency is typically a quartz crystal oscillator, which provides unparalleled accuracy and stability. This also allows for a wide dynamic range, from a few Hz to several MHz.The PLL circuit is composed of four sections; the control section, the frequency multiplier chain, the limiter stage, and the amplifier chain. The control section is responsible for synchronization and adjusting the frequency of the oscillator. The frequency multiplier chain multiplies the reference frequency by a factor of 8 to increase its magnitude. The limiter stage then takes the multiplied frequency and limits it to the desired frequency output. The amplifier chain then amplifies this frequency to the desired output power. Any difference between the reference frequency and the desired output frequency is compensated by the control section.In addition, the SIT9002AC-43H25DB boasts advanced temperature compensation capability, delivering accurate frequency output even over a wide range of temperatures. It also offers built-in crosstalk control and frequency synchronization between modules, allowing for easy integration in multi-module systems. SIT9002AC-43H25DB is a single-chip solution for high-performance and low-failure ac motor control and generator applications. Its advanced temperature compensation, crosstalk control, and frequency synchronization capabilities make it an ideal choice for those looking for a reliable and robust solution.
