Application Field

Working Principle

The SIT9005ACR2D-28SK is a programmable oscillator that is based on the traditional inductive-Capacitive-L (ICL) structure. The ICL structure consists of two inductors, two capacitors, a feedback element and an output divider. The two inductors form an LC tank circuit that creates a sinusoidal signal at the output. The frequency of the oscillation is determined by the resonance frequency of the LC tank. To increase accuracy, the capacitors and inductors are adjusted until the desired output frequency is achieved.

The SIT9005ACR2D-28SK also uses a voltage control system to adjust the frequency of the oscillation. This control system uses a voltage reference to control an oscillator, which is in turn attached to the LC tank. A monitored control feedback loop is employed to ensure accurate frequency control. This system helps alleviate the need for manual tuning and allows for fast frequency changes.

Conclusion

The SIT9005ACR2D-28SK is a programmable oscillator that is designed to provide maximum accuracy and quick frequency changes. Its features make it ideal for communication, electronic equipment, and many other applications. It uses an ICL structure and a voltage control system to provide consistent, accurate oscillations and fast frequency changes.
