AD9970 LVDS output common mode voltage

Please let us know the common mode voltage of AD9970 LVDS output.

 

In our design, the LVDS output of AD9970 is interfacing the Cyclone IV E 2.5V LVDS which has 1.25V common mode voltage.

 

The input signal to Cyclone IV are corrupted some time.

 

We suspect the common mode voltage between them are different.

 

Please let me know the answer.

 

Many thanks.

 

David.
