The LMK04000BISQE/NOPB works on the principle of Phase-Locked Loop (PLL) technology. In this type of circuit, the frequency of the output signal is made to be exactly the same as the frequency of the input signal by controlling an oscillator. The PLL consists of an oscillator (VCO), inputs for reference and feedback signals, a phase detector and an amplifier. The phase detector determines the phase difference between the reference and feedback signals and the amplifier is used to adjust the VCO frequency to that of the input signal.

The LMK04000BISQE/NOPB is designed to provide excellent phase noise performances at different frequencies and applications. The device works at a 54MHz to 6600MHz frequency range, and it requires a low-noise voltage-controlled oscillator (VCO) to achieve the desired performance.
