Working Principle of SIT9005ACL1G-XXDA

The SIT9005ACL1G-XXDA is based on a frequency control circuit design. The heart of the circuit is an on-chip Voltage Controlled Oscillator (VCO). This VCO core is a closed loop oscillator where the control voltage is determined by an external oscillator, an on-chip reference frequency, and an internal voltage reference.

The oscillator is programmed using an on-chip ADC (Analog to Digital Converter) and a programmable counter. The counter is used to adjust the VCO frequency by adjusting the voltage applied to the VCO based on the output of the ADC. The counter also provides a precise width control when the external oscillator is used.

Digital and analog control algorithms built into the ADC/DAC (Digital to Analog Converter) control registers provide precise frequency control and phase synchronization. These algorithms provide accurate control over the frequency, programmability and phase of the oscillator.

The oscillator is configured via an I2C, SPI or serial interface, which allows the programmer to accurately set the frequency and parameters of the oscillator. Furthermore, the oscillator can also be digitally recalibrated if necessary.

Conclusion

The SIT9005ACL1G-XXDA is a high performance programmable oscillator designed for demanding industrial and research applications. Its wide tuning range and excellent frequency stability make it the perfect choice for use in aerospace and military installations, as well as for applications where precise control and communication stability are essential.
