Abstract
A direct digital synthesizer (DDS) includes a phase increment calculator that determines a phase increment for a selected frequency; a phase accumulator that accumulates the phase increment over time and provides an accumulated phase value; a converter that converts the accumulated phase value to an analog signal at the selected frequency; and a phase preset calculator that determines a phase preset value for the selected frequency. The phase accumulator resets the accumulated phase value to the phase preset value at a transition to the selected frequency in a phase coherent mode.
