Signal Descriptions
§
V
CCIN_SENSE
V
SS_VCCIN_SENSE
Isolated, low impedance connection to the processor power and ground. These signals
must be connected to the voltage regulator feedback circuit, which ensures processor
voltage remains within specification.
V
CCIO_IN
Power supply for miscellaneous I/O interfaces of the processor.
V
CCPECI
Power supply for PECI interface of the processor.
V
CCD
Variable power supply for the processor system memory interface. Provided by one
regulator per CPU socket for all memory channels. The valid nominal voltage of this
supply (1.50V or 1.35V) is configured by BIOS after determining the operating voltages
of the installed memory.
Note: The processor must be provided V
CCD
for proper operation, even in
configurations where no memory is populated.
VSS Processor ground node.
