Intel® 820 Chipset Design Guide Addendum for the Intel® Pentium® III Processor for the PGA370 Socket
The Intel® Pentium® III processor for the PGA370 socket is the next generation Intel® Pentium® III processor. The differences between the PGA370 and SECC2 design implementations are detailed in this addendum. The PGA370 design requires additional termination at the chipset for the AGTL+ signals. In addition, the platform power delivery requirements are different for the PGA370 design compared to the SECC2 design. AGTL+ layout considerations detailed in the Intel® 820 Chipset Design Guide still apply to FC-PGA designs (including ground referencing the AGTL+ signals).This is an update to the guidelines contained in the Intel® 820 Chipset Platform Design Guide Revision 1.0 (Order Number: 290631-00x).
