Working Principle

The SIT9005ACA1H-28SB contains a programmable oscillator which is a type of oscillator that is able to generate signals with a frequency which is adjustable by a set of parameters. The parameters can be chosen to change the output frequency to the desired level. The oscillator is based on an I2C bus architecture and consists of two parts. The first is the oscillator control logic block, which is responsible for setting up the output frequency. The second part is the oscillator core, which is responsible for generating the oscillation.

The oscillator core is an analog circuit which integrates components such as capacitors, resistors and transistors to create an oscillating signal. The output of the oscillator is then fed back to the control logic which is responsible for adjusting the various parameters to achieve the desired output frequency. The parameters are adjustable by programming the I2C registers, which allow the user to program the oscillator to a certain frequency.

The programming of the oscillator is done through the I2C interface, which allows the circuit to be easily updated as needed. The oscillator is also equipped with on-chip EMI and ESD protection to ensure that the circuit remains stable even in the presence of strong electrical interference.
