Keywords: DDS application note  filter performance  clock jitter 

[Summary of tips] A reconstruction filter is an important element for creating a clean, low jitter clock signal from a direct digital synthesizer (DDS). A reconstruction filter is used at the output of the DAC to attenuate image frequencies. However, a physical filter cannot be implemented with ideal stop band rejection extending out to infinite......
