Hi Experts,
A customer of ours has one board with microcontroller and 3 slaves. Each slave uses one I2C line. Everything works fine.
Now he wants to separate them into two boards: 1= microcontroller, 2= slaves.
I have attached two images of P82B96DR part of schematics from master(microcontroller) and the slaves.
The two-board setup is not working, because slaves are not ACK the microcontroller during I2C communication.
Since this is his first encounter with the P82B96DR, would you please look at the two schematics and see if everything is alright?
He is also worried maybe pullups values or voltages might be an issue.

Please advise. Thank you.
