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 is interpreted as a
logical low value.
3.
V
IH
is defined as the minimum voltage level at a receiving agent that is interpreted as a
logical high value.
4.
V
IH
and V
OH
may experience excursions above V
CCP
. However, input signal drivers must
comply with the signal quality specifications.
5.
This is the pull-down driver resistance. Measured at 0.31*V
CCP
. R

. R
TT
typical value of 55 Ω is used for R
ON
typ/
min/max calculations.
6.
GTLREF should be generated from V
CCP
with a 1%-tolerance resistor divider. The V
CCP
referred to in these specifications is the instantaneous V
CCP
.
7.
R
TT
is the on-die termination resistance measured at V
OL
of the AGTL+ output driver.
Measured at 0.31*V
CCP
. R
TT
is connected to V
CCP
on die.
8.
Specified with on die R
TT
and R
ON
turned off. Vin between 0 and V
CCP
.
9.
Cpad includes die capacitance only. No package parasitics are included.
10.
This is the external resistor on the comp pins.
11.
On die termination resistance measured at 0.33*V
CCP
.
