The oscillator is also capable of providing an output signal up to 250 MHz. This makes it suitable for applications that need to generate an extremely high precision signal in a short period of time.

The oscillator also features a ± 50 ppm stability which ensures its high accuracy in generating signals even under varying conditions. Its Highly Stable Frequency also makes it a good choice for applications requiring signal stability over a wide range of temperatures. In addition, the SIT9005ACR2D-18SI is available in various frequencies, making it suitable for a wide range of applications.

Working Principle

The working principle behind the SIT9005ACR2D-18SI is that of frequency division. This type of oscillator works by using an input reference clock signal, which is divided down to create the output frequency. The oscillator contains frequency dividers, which are responsible for dividing the input frequency and producing the desired output frequency.

The frequency dividers employed in the SIT9005ACR2D-18SI are digital synthesizers which allow the user to program and fine-tune the frequency division ratio for optimum signal accuracy. This is done by setting two different input frequencies, one for the programmable frequency division ratio (FDR) and the other for the clocking reference signal. The two signals are then combined in a Phase-Locked Loop (PLL) circuit, resulting in the output frequency.

The PLL circuit allows for precise frequency tuning and control. By manipulating the two input frequencies, a variety of output frequencies can be generated with the utmost accuracy. In addition, the output frequency can be changed on the fly, allowing users to adjust the signal as needed.

The SIT9005ACR2D-18SI also contains an adjustable phase shift circuit, which allows for fine-tuning of the frequency division ratio. This circuit ensures that the output frequency is precisely adjusted to the desired value without any phase shift that could result in poor signal quality.

Conclusion

The SIT9005ACR2D-18SI is a Programmable Oscillator with a wide range of applications in the embedded and industrial sectors. Its fast response time, low power consumption, high accuracy and flexibility make it a great choice for applications that require precision signal generation and quick, accurate frequency tuning.

The oscillator works by employing frequency division, which is accomplished through the use of frequency dividers and PLL circuits. The dividers provide the users with the ability to program and tune the frequency division ratio, while the PLL circuit allows for precise adjustment of the output frequency. The adjustable phase shift circuit further ensures that the output frequency is precise and that no phase shift is present.
