Electrical and Thermal Characteristics
1.4.1.4 Output Driver Characteristics
Table 4 provides information on the characteristics of the output drivers referenced in Table 16. The values
are preliminary estimates from an IBIS model and are not tested.
Notes:
1
For DRV_PCI, IOH read from the IBIS listing in the pull-up mode, I(Min) column, at the 0.33V label by
interpolating between the 0.3 V and 0.4 V table entries’ current values which corresponds to the PCI VOH
= 2.97 = 0.9*OVdd (OVdd = 3.3 V) where Table Entry Voltage = OVdd - PCI VOH.
2
For all others with GVdd or OVdd = 3.3 V, IOH read from the IBIS listing in the pull-up mode, I(Min) col-
umn, at the 0.9 V table entry which corresponds to the VOH = 2.4 V where Table Entry Voltage =
GVdd/OVdd - VOH.
3
For DRV_PCI, IOL read from the IBIS listing in the pull-down mode, I(Min) column, at 0.33 V = PCI VOL =
0.1*OVdd (OVdd = 3.3 V) by interpolating between the 0.3 V and 0.4 V table entries.
4
For all others with GVdd or OVdd = 3.3 V, IOL read from the IBIS listing in the pull-down mode, I(Min) col-
umn, at the 0.4 V table entry.
