AD9914- What is the Phase noise value?

Dear Supporter

The AD9914 data sheet specifies that the DDS output phase noise is 128 dBc/Hz (1 kHz offset at 1396 MHz) .

Question:

If the REF clock phase noise is -110dBc/Hz, can I get a phase noise of -128dBC/Hz at the DDS output?

Any idea/recommended configuration is welcomed.

Thanks

Fred
