Electrical Specifications
NOTES:
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
CCP
. However, input signal drivers must comply with the
signal quality specifications.
5.
This is the pulldown driver resistance. Measured at 0.31*V
CCP
. R

(min) = 0.418*R
TT
, R

(typ) =
0.455*R

,
R
ON
(max) = 0.527*R
TT
. R
TT
typical value of 55
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. Refer to processor I/O buffer models for I/V characteristics.
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
.
12.
Applies to Signals A[35:3].
13.
Applies to Signals D[63:0].
14.
Applies to Signals BPRI#, DEFER#, PREQ#, PREST#, RS[2:0]#, TRDY#, ADS#, BNR#, BPM[3:0], BR0#,
DBSY#, DRDY#, HIT#, HITM#, LOCK#, PRDY#, DPWR#, DSTB[1:0]#, DSTBP[3:0] and DSTBN[3:0]#.
