The output waveform is a low jitter and low-distortion sine wave.

The SIT8208AC-21-28E-72.000000Y is used in applications such as:

• Computer systems - This oscillator is ideal for ensuring system stability and providing reliable timing in computer systems.

• Cellular communication - This oscillator can provide the precise frequency required for modern cellular communication networks.

• GPS satellite receivers - This oscillator can provide a very accurate and stable signal for GPS receivers.

• Automotive electronics - This oscillator is used in a wide range of automotive electronic applications to ensure timing accuracy.

The working principle of the SIT8208AC-21-28E-72.000000Y oscillator is based on the use of a reference frequency and a frequency divider. The reference frequency is applied to the input of the frequency divided to produce a divided output, which is then used to drive the output stage of the oscillator. The frequency divided also has a digitally controlled capacitor (DCC), which is used to control the output frequency of the oscillator.

The DCC is controlled by an external voltage signal, such as a resistive divider voltage, and this voltage signal is used to adjust the output frequency of the oscillator. The output frequency can be adjusted up or down based on the external voltage signal, and is usually tuned to the required frequency to ensure accuracy. The DCC also has a temperature compensation circuit, which helps to ensure the output frequency remains stable even when subject to temperature variations.

The SIT8208AC-21-28E-72.000000Y oscillator is a highly reliable and accurate device, suitable for many applications. Its combination of a digitally controlled tuning facility and temperature compensation ensures it can provide a reliable and stable oscillating signal in any environment.
