DS64BR401: VDD voltage

Part Number: DS64BR401
Other Parts Discussed in Thread: LMH1228

Hi support team, 

My customer wants to use this device, in case SMBus supply voltage is 3.3V and VDD is 2.5V.

from the electrical characteristic, that seems no wrong.

However the datasheet is written this sentence that I attached.

 Is it ok to use DS64BR401  if  SMBus supply voltage is 3.3V and VDD is 2.5V?

and  Is it ok to use LMH1228  if  SMBus supply voltage is 3.3V and VDD is 2.5V either?

Regards, 

Shoo
