摘要：
A direct digital synthesizer (DDS) (300) that uses a system for reducing spurious emissions in a digital-to-time converter (DTC) (317). The DDS (300) includes one or more dither sources (307) and a random access memory (RAM) (305). The RAM (305) utilizes a look-up table for storing delay error values by using an output of the look-up table which is combined with the dither source (307) to compensate unequal unit delay values in the DTC (317).
