AD9484 input Vcomm query

  Hi ADI Enineers : 

   I  intend to use ADA4939-1 to drive AD9484 , DC coupled , ADA4939-1 output 1V Vp-p volatge , AD9484's CML output 1.7V voltage , so ADA4939's positive output will reach to 2.2V , It seems exceed the absolute maxim VIN+ . Could you help give some advice ? Thanks .
