The Quad-Core Intel® Xeon® Processor 5400 Series is intended for high performance
server and workstation systems. The Quad-Core Intel® Xeon® Processor 5400 Series
supports a Dual Independent Bus (DIB) architecture with one processor on each bus,
up to two processor sockets in a system. The DIB architecture provides improved
performance by allowing increased FSB speeds and bandwidth. The Quad-Core Intel®
Xeon® Processor 5400 Series will be packaged in an FC-LGA Land Grid Array package
with 771 lands for improved power delivery. It utilizes a surface mount LGA771 socket
that supports Direct Socket Loading (DSL).

) is shared and must connect to all FSB agents. The processor core voltage
utilizes power delivery guidelines specified by VRM/EVRD 11.0 and its associated load
line (see Voltage Regulator Module (VRM) and Enterprise Voltage Regulator-Down
(EVRD) 11.0 Design Guidelines for further details). VRM/EVRD 11.0 will support the
power requirements of all frequencies of the Quad-Core Intel® Xeon® Processor 5400
Series including Flexible Motherboard Guidelines (FMB) (see

the appropriate platform design guidelines for implementation details.
The Quad-Core Intel® Xeon® Processor 5400 Series supports either 1066 MHz,
1333 MHz, or 1600 MHz Front Side Bus operations. The FSB utilizes a split-transaction,
deferred reply protocol and Source-Synchronous Transfer (SST) of address and data to
improve performance. The processor transfers data four times per bus clock (4X data
transfer rate, as in AGP 4X). Along with the 4X data bus, the address bus can deliver
addresses two times per bus clock and is referred to as a ‘double-clocked’ or a 2X
address bus. In addition, the Request Phase completes in one clock cycle. The FSB is
also used to deliver interrupts.

Terminology
A ‘#’ symbol after a signal name refers to an active low signal, indicating a signal is in
the asserted state when driven to a low level. For example, when RESET# is low, a
reset has been requested. Conversely, when NMI is high, a nonmaskable interrupt has
occurred. In the case of signals where the name does not imply an active state but
describes part of a binary sequence (such as address or data), the ‘#’ symbol implies
that the signal is inverted. For example, D[3:0] = ‘HLHL’ refers to a hex ‘A’, and
D[3:0]# = ‘LHLH’ also refers to a hex ‘A’ (H= High logic level, L= Low logic level).
