Absolute phase noise of AD9914 is mentioned in datasheet using SMA 100 Signal generator clock of 3.5 GHz with clock buffered device ADCLK925. 

How much phase noise degradation happened from DDS generator using different external clock 3.5 GHz having 20 dB relative more phase noise with respect to SMA 100 signal generator in linear region up to 10 KHz offset.
