Hi Guys,

 

We met a strange phenomena in using AD9928.

In the datasheet(Rev. SpE) page 30, Figure 43,

In the datasheet it says only the 14 MSBs of the 16bit is valid data, the 2 LSBs are 0.

 

While in our test, in normal data output, we will get signal on the 2LSB.

 

I shall mention here that we have get the correct LVDS test data.
Thanks very much for help.
