Hi,
We found a non-monotonic at the falling edge of both SCL and SDA near the UCD90120A pins in our system.
My question is, does the SCL and SDA of the PMBUS of UCD90120A have internal Schmitt Trigger inputs?
If have, we not need to worry much about the non-monotic. Tuning the termination will cause the rise time of the I2C signal more than 300ns which not meet the I2C standard spec.
Thanks.
