Electrical Specifications
34 Document Number: 318080-002
Notes:
1. The V
CC_MIN
and V
CC_MAX
loadlines represent static and transient limits. Please see Section 2.11.3 for VCC
overshoot specifications.
2. Refer to Table 2-9 for processor VID information.
3. Refer to Table 2-10 for V
CC
Static and Transient Tolerance
4. The load lines specify voltage limits at the die measured at the VCC_SENSE and VSS_SENSE pins and the
VCC_SENSE2 and VSS_SENSE2 pins. Voltage regulation feedback for voltage regulator circuits must also
be taken from processor VCC_SENSE2 and VSS_SENSE2 pins. Refer to the Voltage Regulator Module
(VRM) and Enterprise Voltage Regulator Down (EVRD) 11.0 Design Guidelines for socket load line
guidelines and VR implementation. Please refer to the appropriate platform design guide for details on VR
implementation.
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
TT
. 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. GTLREF should be generated from V
TT
with a 1% tolerance resistor divider. The V
TT
referred to in these
specifications is the instantaneous V
TT
.
7. Specified when on-die R
TT
and R
ON
are turned off. V
IN
between 0 and V
TT
.
8. This is the measurement at the pin.
