The SIT8208AI-81-25S-27.000000Y is a synthesized VCO with the high performance of integer-N frequency synchronization capability and extremely low phase noise, making it ideal for a wide range of applications. It can be used in wireless communications systems, such as cellular phones and vehicular systems; in video broadcast systems; in digital TV systems; in multi-mode base stations; in satellite communications systems; and in satellite navigation systems. It can also be used for frequency synthesizers, frequency hopping systems, frequency modulation systems, and data communication systems.

SIT8208AI-81-25S-27.000000Y Working Principle

The working principle of the SIT8208AI-81-25S-27.000000Y is based on the alternating configuration of two frequency dividers. This configuration provides a constant oscillation frequency that is determined by two parameters: the reference frequency and the ratio between the dividers. This ratio is set by digital control signals applied to the divider. These control signals are the input for the frequency control.The SIT8208AI-81-25S-27.000000Y supports various frequency ranges, and the oscillation frequency can be changed by selecting an appropriate reference frequency. With this oscillator, the switching speed between different frequencies is exceptionally fast, and the same type of oscillator can also be used for different frequency bands by simply changing the reference frequency. Additionally, the phase noise levels generated by the oscillator are very low, which helps maintain the stability of the oscillator.In short, the SIT8208AI-81-25S-27.000000Y is a high-performance synthesized VCO that is widely used for many applications. It is a low-phase noise, high-speed synthesized VCO with excellent frequency synchronization capability, making it ideal for a variety of applications from wireless communications and digital TV systems to satellite communications and navigation systems.
