• Working Principle of SIT9002AC-43H25DX

The SIT9002AC-43H25DX operates using a PLL (Phase Locked Loop) looping architecture. It utilizes a voltage controlled oscillator (VCO) which is controlled by the PLL loop. The PLL loop determines the output frequency of the oscillator based on a reference input, typically a crystal oscillator.The voltage controlled oscillator of the SIT9002AC-43H25DX is made up of a pair of transistors connected in a differential configuration. The oscillator is capable of producing a frequency range of 1MHz to 75MHz. The output signals from the oscillator are then fed into a divider circuit, where the frequency is divided by a programmable divider ratio.The output of the divider circuit is then fed into a phase comparator. The phase comparator compares the input frequency with a reference frequency, and produces an output error signal proportional to the difference between the two. The error signal is then used to control the VCO, by varying the voltage applied to the VCO. This keeps the output frequency of the oscillator in lock with the reference frequency.The SIT9002AC-43H25DX also includes a serial interface which allows the configuration of the PLL loop as well as programming of frequency, output voltage levels, and timing parameters. This allows the user to easily adjust and configure the oscillator for a wide range of applications.
