DDS Refout & Refin (AD9835)

I have developed the evaluation boards for AD9835 (as per datasheet), As mentioned in datasheet REFOUT should generate 1.2V but in my case its 0V and 2V on Refernce pin, without connecting any external supply to REFIN.


When I short REFIN to REFOUT I get 0V, Ideally it should be 1.2V. ( mentioned in data-sheet).


Please help me to understand the same.
