The article focuses on a simulation model which was developed to understand hybrid-clock, third-order sources of direct-digital synthesizer (DDS). The model is aimed at understanding the application of DDS sources in phase-sensitive fields such as satellite navigation receivers. When the DDS accumulator is used in a field-programmable gate array (FPGA), the output is less than the input by one clock cycle.
