AD9691 Power supply recommendations error?

Power supply recommendation, Figure 83, in the AD9691(Rev 0) datasheet,

 

3.3V Input -> ADP2164 (1.8V) -> ADP125 -> AVDD1_SR

 

It is normal power supply sequence as I know.

 

But in the ADP125(Rev D) datasheet,

Input voltage supply range of ADP125 is between 2.3V and 5.5V.

 

It is NOT include 1.8V.

 

I wonder I can design as figure 83? ( = ADP125 have more range?)

 

or I must some modify?
