Other Parts Discussed in Thread: AM3357
Dear,
We are evaluating Signal Integrity of MII interface between the AM3357 and the TLK105L on our board.
We found that there is the undershoot on the PR1_MII0_TXEN sginal which is beyond the Absolute Maximum
Rating (-300[mV]) of the TLK105L(PHY) for 575[psec] and reaches -570[mV].
We know this is un-guaranteed condition, but could you tell us the following?
In detail, please check the attached file.
Thank you.
