problem to connect the AD9643 and AD9684 to FPGA!

[javad2040]

hello guys.
I designed a data acquisition system with AD9643 and AD9684 ADC and ZYNQ-FPGA.
The ZYNQ-FPGA has two type of banks: HP(High Performance : 1.0v to 1.8v) and HR(High Range : 1.0v to 3.3v).
I have forced connect the AD9643 and AD9684 to HP bank, the interface of this ADCs is LVDS, the Vcm of both ADC is roughly 1.2v and FPGA has Vcm=1.2v for LVDS inputs.
I set the HP banks voltage to 1.8v and my question is that this manner is correct or not?
Can i connect the ADC to FPGA banks with 2.5 voltage?
please help me to solve this problem.

HP, LVDS, VCCO = 1.8V

or

HR, LVDS_25, VCCO = 2.5V
