ADV7390 using VDD_IO @ 2.5V

Hello,

 

In the datasheet of the ADV7390/1/2/3 it is stated that VDD_IO should be 1.8V or 3.3V (page 20), but VDD_IO can be between 1.71V and 3.63 (page 7).

 

1) Can i use this chips with a 2.5V or 2.8V  power supply for VDD_IO ?

 

2) are the Vih and Vil are defined like 1.8V power supply (0.7Vdd_io for Vih and 0.3Vddio for Vil) ?

 

3) How the digital timings are affected by this changes ?

 

Best Regards.
