I am using HDMI TX ADV7511W with its digital inputs interfaced to FPGA (Virtex 7).

The datasheet mentions that its video/audio logic accepts levels from 1.8V to 3.3V.

The IC ADV7511W has 1.8V Supply Voltage (DVDD, AVDD, PVDD, BGVDD) and 3.3V Supply Voltage (DVDD_3V). There is no specific IO voltage pin (like DVDD_IO for some other interfaces). So how does it know which IO Voltage its working with? 

Can I interface its digital inputs with LVCMOS18 IO standard working on 1.8V IO interfaced to FPGA?
