Electrical Characteristics
2. The supply voltage must stay within the DC min/max window in a static system (no active switching). The
DC window only assumes voltage regulator ripple and motherboard induced noise
3. Intel 5000P Chipset MCH with 4 active FB-DIMM channels. Total Core + I/O current drawn off the 1.5 Vrail
4. Intel 5000X Chipset MCH with 4 active FB-DIMM channels. Total Core + I/O current drawn off the 1.5 V rail
5. Intel 5000V Chipset MCH with 2 active FB-DIMM channels. Total Core + I/O current drawn off the 1.5 V rail
6. Tolerances are specified at the AMB DRAM package(s) and FB-DIMM voltage regulator designs should be
scaled accordingly to support these tolerances for the 1.5. DC min/max per the JEDEC specification. AC
tolerances from VR loop BW ~30 kHz to 1 MHz.

1. The analog voltage is intended to be a filtered copy of its associated supply voltage. Refer to the New Dual-
Core Intel® Xeon® Processor-Based Servers Platform Design Guide (PDG) for the recommended
implementation and frequency response requirements of each filter.

DC Characteristics
This section documents the DC characteristics of the MCH. The specifications are split
into five sections:
• Clocks
• FSB Interface
• FB-DIMM (Fully Buffered DIMM) Memory Interface¹
• PCI Express/ ESI Interface
• Miscellaneous Interface
— SMBus Interface
— JTAG Interface
1. Refer to the Intel^® 6400/6402 Advanced Memory Buffered External Design Specification (EDS)
Addendum for additional details on the FB-DIMM interface.
