Electrical Specifications
NOTES:
1.
1.
Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2.
V
IL
is defined as the maximum voltage level at a receiving agent that will be interpreted as
a logical low value.
3.
V
IH
is defined as the minimum voltage level at a receiving agent that will be interpreted as
a logical high value.
4.
V
IH
and V
OH
may experience excursions above V
CCSM
. However, input signal drivers must
comply with the signal quality specifications.
5.
This is the pull down driver resistance.
6.
V
CCSM
varies with typical/min/max cases. Refer
for details.
7.
DDR_VREF could either be from external or internal reference voltage.
