Design Guide Introduction
1
This design guide documents Intel’s design recommendations for dual-processor systems based on the
Intel
®
Pentium
®
III Processor with 512KB L2 Cache and the Intel
®
Pentium
®
III Processor (CPUID
068xh) with AGTL signalling capability for use with the ServerWorks* HE-SL chipset. In addition to
providing motherboard design recommendations such as layout and routing guidelines, this document
will also address possible system design issues such as processor power delivery, layout considerations
for mechanical pieces, EMI design impacts and system bus decoupling.
Please note that this document describes the design recommendations that are driven by the Intel
®
Pentium
®
III Processor with 512KB L2 Cache’s specifications. Because of this, the recommendations
explicity mentioned the Intel
®
Pentium
®
III Processor with 512KB L2 Cache in most places. The Intel
®
Pentium
®
III Processor (CPUID 068xh) with AGTL signalling capability is compatible with systems
designed to the recommendations in this document and will operate in its AGTL compatible mode when
placed in the system.
Carefully follow the design information, board schematics, debug recommendations and system
checklist presented in this document. These design guidelines have been developed to ensure maximum
flexibility for board designers while reducing the risk of board related issues. The design information
provided in this document falls into one of the two categories below.
•
Design Recommendations are items based on Intel's simulations and lab experience to date and
are strongly recommended, if not necessary, to meet the timing and signal quality specifications.
•
Design Considerations are suggestions for platform design that provide one way to meet the
design recommendations. They are based on the reference platforms designed by Intel. They should
be used as an example, but may not be applicable to your particular design.
1.1
Audience
This document is targeted at the following audience:
•
Intel
®
Pentium
®
III Processor with 512KB L2 Cache system developers;
•
System developers modifying an existing PGA370 socket dual-processing platform to be Intel
®
Pentium
®
III Processor with 512KB L2 Cache ready.
