Minimum V

CC

 and maximum I

CC

 are specified at the maximum processor case temperature 

(TCASE) shown in 

.

9.

This specification refers to the total reduction of the load line due to VID transitions below 
the specified VID.

10.

Individual processor VID values may be calibrated during manufacturing such that two 
devices at the same frequency may have different VID settings.

11.

This specification applies to the VCCPLL land.

12.

Baseboard bandwidth is limited to 20 MHz.

13.

I

CC_TDC

 is the sustained (DC equivalent) current that the processor is capable of drawing 

indefinitely and should be used for the voltage regulator temperature assessment. The 
voltage regulator is responsible for monitoring its temperature and asserting the necessary 
signal to inform the processor of a thermal excursion. The processor is capable of drawing 
I

CC_TDC

 indefinitely. Refer to 

 for further details on the average processor current 

draw over various time durations. This parameter is based on design characterization and 
is not tested.

14.

This is the maximum total current drawn from the V

TT

 plane by only one processor with R

TT

 

enabled. This specification does not include the current coming from on-board termination 
(R

TT

), through the signal line. Refer to  the Voltage Regulator Design Guidelines to 

determine the total I

TT

 drawn by the system. This parameter is based on design 

characterization and is not tested.

15.

I

OUT

 is specified at 1.1 V.

16.

I

CC_RESET

 is specified while PWRGOOD and RESET# are asserted.

17.

The processor is intended for dual processor workstations only.

NOTES:
1.

Processor or Voltage Regulator thermal protection circuitry should not trip for load currents 
greater than I

CC_TDC

.
