An application of direct digital frequency synthesizer at frequency transform circuit
This paper introduces a solution of frequency converter that generates a 10.24MHz high-stability signal from a 10MHz high-stability reference source.This design is based on Direct Digital Synthesis(DDS).For DDS devices,internal or external high-order multiplier circuits are no longer used,and the output frequency and phase can be step-adjusted.The synthesized 10.24MHz signal can be used as a high-stability clock reference of the phase-locked loop circuit after subsequent noise suppression and filtering processing,thereby improving the accuracy and stability of the output signal frequency of the phase-locked loop circuit.
