Working Principle

The 849N202CKI-999LF has a several-step process for clock generation. First, it takes an input signal, which can be either digital or analog, and uses a voltage-controlled oscillator (VCO) to generate a high frequency clock signal. The VCO takes the input signal and turns it into a steady and high-resolution clock signal. The signal is then routed through a prescaler, which divides the signal by a specified number to obtain a lower frequency clock signal. This signal is passed through a phase detector circuit, which measures the phase difference between the reference signal and the synthesized signal to create a control voltage. This voltage is then used to adjust the frequency of the VCO, thereby allowing for precise clock signal generation. Finally, the signal is routed through a frequency multiplier, which can boost the signal up to its final output frequency.

Overall, the 849N202CKI-999LF is an excellent choice for applications that require precise timing and frequency hopping capabilities. It has a wide variety of uses and offers excellent noise suppression and fast switching capabilities.
