Isolation I2C with ADuM1250

I used ADuM1250 to isolate I2C Bus. I have only 1 Master and 1 Slave on bus with 2

different voltage power.

The problem is that the ADuM made a drop in communication periodically. I saw

that the communication is failed for a split second then it come again.

I tried removing the ADuM and bridging the bus and also replacing with a new ADuM.

The communication seems to be all right then.

I can't figure it out, why would it be? I hope that someone can point me something to

find out.

Thank in advance.
