Other Parts Discussed in Thread: LM96080
Hi team,
My customer use the AMC80 in their system, and the I2C communication has some issue.
Below is the schematic and diagram of the AMC80.

So after power up, they will firstly use the CPLD to reset the AMC80 and then do some read in AMC80 by the I2C of CPLD.
But it there is no ACK from AMC80 and cause the failure of I2C communication between the CPLD and AMC80.
Below is the I2C wave:
Please help to check the schematic and the I2C waveform.
And give your comment, what may be the cause for the failure communication of I2C?

Thanks a lot!
