[hpsdr] questions re: output spurs using an AD9954 DDS chip

[Steven M. Simons]

To the list;

Built up a uP driven DDS circuit (to obtain a 10>100MHz output) using the
AD9954 chip. Upon looking at the spectral output, I see lots of close in
spurs. As this is a 1st attempt to use this chip, is there anything written
on how to clean up the output??? 

Thanks,

Steve
