Electrical Specifications
This chapter describes processor signaling, DC specifications, and signal quality.
References to various interfaces (memory, PCIe*, Intel QPI, PECI, etc.) are also
described.
Integrated Voltage Regulation
A new feature to the processor is the integration of platform voltage regulators into
the processor. Due to this integration, the processor has one main voltage rail (V
CCIN
)
and a voltage rail for the memory interface (V
CCD01,
V
CCD23
- one for each memory
channel pair), compared to five voltage rails (V
CC
, V
TTA
, V
TTD
, V
SA
, and V
CCPLL
) on
previous processors. The V
CCIN
voltage rail will supply the integrated voltage
regulators which in turn will regulate to the appropriate voltages for the cores, cache,
and system agents. This integration allows the processor to better control on-die
voltages to optimize for both performance and power savings. The processor V
CCIN
rail
will remain a sVID -based voltage with a loadline similar to the core voltage rail (called
V
CC
) in previous processors.
Processor Signaling
The Intel
®
Xeon
®
processor E5-1600 and E5-2600 v3 product families includes 2011
lands, which utilize various signaling technologies. Signals are grouped by electrical
characteristics and buffer type into various signal groups. These include DDR4
(Reference Clock, Command, Control, and Data), PCI Express*, DMI2, Intel
®
QuickPath Interconnect, Platform Environmental Control Interface (PECI), System
Reference Clock, SMBus, JTAG and Test Access Port (TAP), SVID Interface, Processor
Asynchronous Sideband, Miscellaneous, and Power/Other signals. Refer to
on
page 23 for details.
System Memory Interface Signal Groups
The system memory interface utilizes DDR4 technology, which consists of numerous
signal groups. These include: Reference Clocks, Command Signals, Control Signals,
and Data Signals. Each group consists of numerous signals, which may utilize various
