Electrical Specifications
3.
These voltages are targets only. A variable voltage source should exist on systems in the
event that a different voltage is required. See
event that a different voltage is required. See
and
for more
information.
4.
The voltage specification requirements are measured across VCC_SENSE and VSS_SENSE
lands at the socket with a 100 MHz bandwidth oscilloscope, 1.5 pF maximum probe
capacitance, and 1 M minimum impedance. The maximum length of ground wire on the
probe should be less than 5 mm. Ensure external noise from the system is not coupled into
the oscilloscope probe.

Refer to
, for the minimum, typical, and maximum V
CC
allowed for a
given current. The processor should not be subjected to any V
CC
and I
CC
combination
wherein V
CC
exceeds V
CC_MAX
for a given current.

loadline. Refer to

must be provided using a separate voltage source and not be connected to V
CC
. This
specification is measured at the land.
8.
Baseboard bandwidth is limited to 20 MHz.
9.
This is the maximum total current drawn from the V
TT
plane by only the processor. This
specification does not include the current coming from on-board termination (R
TT
),
through the signal line. Refer to the Voltage Regulator Design Guide to determine the total
I
I
TT
drawn by the system. This parameter is based on design characterization and is not
tested.

Adherence to the voltage specifications for the processor are required to ensure reliable
processor operation.
processor operation.
NOTES:
1.
The loadline specification includes both static and transient limits except for overshoot allowed as shown in
2.
3.
The loadlines specify voltage limits at the die measured at the VCC_SENSE and VSS_SENSE lands. Voltage
regulation feedback for voltage regulator circuits must be taken from processor VCC and VSS lands. Refer
to the Voltage Regulator Design Guide for socket loadline guidelines and VR implementation details.
4.
Adherence to this loadline specification is required to ensure reliable processor operation.
