Hi Bala,
Many Ethernet PHY datasheets mentioned this 5% as overshoot value for
Network interface signals(I.e MDI signals towards magnetic transformr).Does
it sounds like same value.?

Subject: [SI-LIST] Reg:Overshoot and undershoot levels for 100mbps MII
signals
Hi Team,
In our design i am using One Ethernet PHY supporting 10/100 Mbps speed.I
carrying out Signal Integrity simulation for this interface.I checkedthem
various datasheets of Ethernet PHY from various manufacturers ,none of
provide Overshoot and Undershoot details for the MII signals between MAC,an
and PHY.
Could you please provide Overshoot and Undershoot details and suggest on
the following .
" I gone through IEEE802.3 standard, under section 22.4 it is given as
overshoot of 7.5 volts and undershoot of -1.8 volts with a duration notreference.
exceeding 15ns is allowed for this signals." May i take this as
