ADuM2250 I2C Isolator DC Power Supply voltage level

I am using ADUM 2250 I2C 5KV rms Isolator in my design. The VDD1 = 3.0 V DC is connected to 1st Micro controller SCL and SDA pins and VDD2 = 3.3V DC connected to 2nd Micro controller isolated SCL and SDA pins. Is it ok to use VDD1 = 3.0 V DC and VDD2 = 3.3 V DC or both should be equal ( VDD2 = 3.0V DC only) for proper functioning of ADuM 2250 IC
