Lastly, the frequency accuracy can be achieved with the use of an internal trimmer.

Working Principle

The DSC2033FL2-F0028T works by modulating a quartz crystal, effectively changing its frequency. The oscillator maintains its frequency by constantly monitoring the crystal\'s frequency and then modulating the quartz crystal again until it reaches the desired frequency. This modulation is achieved through the use of an onboard comparator, which compares the reference frequency to the output frequency. The difference between the reference and output frequency is used to fine-tune the oscillator until it reaches the desired frequency. This process is repeated until the oscillator is at the correct frequency. Furthermore, the adjustable output frequency is ensured by the use of a divider and customer selectable connection pins.

Conclusion

The DSC2033FL2-F0028T is a pin configurable/selectable oscillator that combines the features and capabilities of both a programmable crystal oscillator and an adjustable frequency oscillator. Its output frequency and duty cycle can be adjusted and optimized through the use of an extra pin. Additionally, it provides excellent temperature stability and low power consumption, making it ideal for various applications such as radio frequencies, high precision timing, and data acquisition. Finally, its working principle involves a quartz crystal that is monitored and modulated in order to reach the desired frequency and accuracy.
