Power, Ground and Sense Signals
Processors also include various other signals, including power / ground and sense
points. Details can be found in Table 7 on page 23.
Power and Ground Lands
All VCCD, VCCIN, and VCCIO_IN, and VCCPECI lands must be connected to their respective
processor power planes, while all VSS lands must be connected to the system ground
plane.
For clean on-chip power distribution, processors include lands for all required voltage
supplies. These are listed in the following table.

Each VCCIN land must be supplied with the voltage determined
by the SVID Bus signals. Table 5 on page 21 defines the
voltage level associated with each core SVID pattern. Table 15
on page 34 and Figure 4 on page 35 represent VCCIN static
and transient limits.

Each VCCD land is connected to a switchable 1.20 V supply,
provide power to the processor DDR4 interface.
VCCD is also controlled by the SVID Bus. VCCD is the generic
term for VCCD_01 and VCCD_23.

Decoupling Guidelines
Due to its large number of transistors and high internal clock speeds, the Intel®
Xeon® processor E5-1600 and E5-2600 v3 product families is capable of generating
large current swings between low and full power states. This may cause voltages on
power planes to sag below their minimum values if bulk decoupling is not adequate.
Large electrolytic bulk capacitors (CBULK), help maintain the output voltage during
current transients, for example coming out of an idle condition. Care must be taken in
the baseboard design to ensure that the voltages provided to the processor remain
within the specifications listed in Table 13 on page 31. Failure to do so can result in
timing violations or reduced lifetime of the processor.
Voltage Identification (VID)
The reference voltage or the VID setting is set via the SVID communication bus
between the processor and the voltage regulator controller chip. The VID settings are
the nominal voltages to be delivered to the processor's VCCIN lands. Table 5 on page
21 specifies the reference voltage level corresponding to the VID value transmitted
over serial VID. The VID codes will change due to temperature and/or current load
changes in order to minimize the power and to maximize the performance of the part.
The specifications are set so that a voltage regulator can operate with all supported
frequencies.
Individual processor VID values may be calibrated during manufacturing such that two
processor units with the same core frequency may have different default VID settings.
