NOTES:
1.
Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2.
VIL is defined as the maximum voltage level at a receiving agent that will be interpreted as
a logical low value.
3.
VIH is defined as the minimum voltage level at a receiving agent that will be interpreted as
a logical high value.
4.
VIH and VOH may experience excursions above VCCSM. However, input signal drivers must
comply with the signal quality specifications.
5.
This is the pull down driver resistance. Refer to processor I/O Buffer Models for I/V
characteristics.
6.
The minimum and maximum values for these signals are programmable by BIOS
7.
DDR2 values are pre-silicon estimations and subject to change.
8.
VCCSM varies with typical/min/max cases. Refer Table 4-29 for details.
9.
Determined with 2x Buffer Strength Settings into a 50 to 0.5x VCCSM test load.
10. DDR_VREF could either be from external or internal reference voltage.
