Output Voltage Requirements
Notes:
1. These values are either pre-silicon or the latest known values and are subject to change. See the respective
Processor’s Electrical, Mechanical, and Thermal Specifications (EMTS) for the latest IccTDC and IccMAX
specifications.
2. FMB = Planned Flexible Motherboard guideline for processor end-of-life.
3. Voltage regulator thermal protection circuitry should not trip for load currents greater than ICCTDC
4. For platforms designed to support several processors, the highest current value should be used.
5. For platforms designed to support a single specific processor, only use that processor’s current
requirements.
2.2 Load Line Definitions - REQUIRED
To ensure processor reliability and performance, platform DC and AC transient voltage
regulation must be contained within the V
CCMIN and the VCCMAX die load line
boundaries, except for short burst transients above the V
CCMAX as specified in
Section 2.4. Die load line compliance must be guaranteed across 3-sigma component
manufacturing tolerances, thermal variation and age degradation. The following load
line contains static and transient voltage regulation data as well as maximum and
minimum voltage levels. It is required that the regulator’s positive and negative
differential remote sense pins be connected to both the V
CC_DIE_SENSE, VSS_DIE_SENSE,
V
CC_DIE_SENSE2 and VSS_DIE_SENSE2 pin pairs of the processor socket, see Figure 3-1.
The prefix V
CC is designated for the positive remote sense signal and the VSS prefix for
the negative remote sense signal.
