I believe you will find that these pins are really analog in nature not
digital. Thus no IBIS models for them.

Subject: [IBIS] IBIS models for Intel LXT971A and LXT9785 Ethernet PHYs
I've obtained IBIS models "lxt971a_q_mii_3_31.ibs" and
"lxt9785_q_rmii_3_3.ibs" of the above-mentioned devices through the
following link:
http://www.intel.com/design/network/products/ethernet/linecard_ept.htm
<http://www.intel.com/design/network/products/ethernet/linecard_ept.htm>
Unfortunately the IBIS model for LXT9785 device does not show which I/O
models should be used for the 100Mbps pins: TPFOP, TPFON, TPFIP, TPFIN. The
IBIS model for LXT971A does not show the I/O models for the TPFOP, TPFON
pins.
I need the models for those pins to be able to perform signal integrity
analysis of a magneticless link through a backplane.
Does anyone have info on the missing models? Are those the right IBIS model
files for my analysis?
Thanks.
Hassan.
