I wonder knowing the realtionship the phase noise of output of DDS and clock phase noise
The relationship between the noise on the output of the DDS and the noise of the reference clock source is a direct one. There is no inherent filtering process within the DDS. You will typically find plots in the DDS datasheets of the 'residual' phase noise. This represents the noise you can expect to be added to the clock phase noise by the DDS.
