Electrical Specifications
5. Refer to Table 5 and Figure 1, 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.
6. I
CC_MAX
specification is based on V
CC_MAX
loadline. Refer to Figure 1 for details.
7. V
TT
must be provided via 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
TT
drawn by the system. This parameter is based on design characterization and is not
tested.
10. Adherence to the voltage specifications for the processor are required to ensure reliable
processor operation.
NOTES:
1. The loadline specification includes both static and transient limits except for overshoot
allowed as shown in Section 2.6.3.
2. This table is intended to aid in reading discrete points on Figure 1.
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.
