Working Principle of the CDCVF857GQLR

The CDCVF857GQLR is a combination of a clock generator and a Phase Locked Loop (PLL) component. It is an AC coupled device and operates using an external crystal oscillator as an input. The oscillator then passes through a programmable, low-pass filter and an amplifier to reduce jitter and noise. The input signal is then divided by a programmable set of integers and a set of diodes to generate a programmable set of clock frequencies.

From this point, the output of the clock generator is passed through a voltage controlled oscillator, which is capable of producing output clock signals with varying frequencies and phases. The output of the voltage controlled oscillator is then passed through the PLL, which is able to compare the input signal to the feedback loop and make any necessary corrections in order to ensure that the output frequency is within a certain accuracy range. The output frequency will then be the same as the set frequency. This allows the device to have accurate control over the output frequency.
