NOTES:
1. Under no circumstances may the 1.5V supply voltage go past the AC min/max window. the 1.5V supply
voltage window may go outside the DC min/max window for transient events.
2. Note that the VCCEXP balls on the Intel® 6702PXH 64-bit PCI Hub should be inductively isolated from the
VCC balls to avoid potential noise injection from the core onto the VCCEXP rail, which is particularly sensitive
to AC noise. Refer to the appropriate Intel® 6702PXH 64-bit PCI Hub sections of the associated Platform
Design Guide for suggestions on how to achieve this isolation.
3. DC specification applies to conditions at frequencies below 5MHz. AC specification applies to transient
conditions at frequencies above 5MHz.
4. The VCCBGEXP rail can tolerate no more than +/- 10mV AC noise about the DC voltage, which must be
fixed within the DC limits shown.
5. The analog voltages are intended to be a filtered copy of the associated supply voltage. Refer to the Intel®
6702PXH 64-bit PCI Hub sections of the associated Platform Design Guide for reference implementation of
the filter and the filter response curve.
Table 4-2 and Table 4-3 apply only to the Intel® 6702PXH 64-bit PCI Hub, except where noted to
also apply to the Intel® 6702PXH 64-bit PCI Hub.
