Electrical Specifications
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. V
IL
is defined as the voltage range at a receiving agent that will be interpreted as a logical
low value.
3. V
IH
is defined as the voltage range at a receiving agent that will be interpreted as a logical
high value.
4. V
IH
and V
OH
may experience excursions above V
TT
. However, input signal drivers must
comply with the signal quality specifications in Chapter 3.
5. Refer to processor I/O Buffer Models for I/V characteristics.
6. The V
TT
referred to in these specifications is the instantaneous V
TT
.
7. Leakage to V
SS
with land held at V
TT
.
8. Leakage to V
TT
with land held at 300mV.
NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processor frequencies.
2. Measured at V
