Figure 12-1: PWRGD Relationship
The PWRGD inputs to the Intel® 450NX PCIset and to the Pentium® II Xeon⢠processor(s)
should be driven with an âANDâ of âPower-Goodâ signals from the 5 V, 3.3 V and VCCcoreP
supplies. The output of this logic should be a 3.3 V level and should have a pull-down resistor
at the output to cover the period when this logic is not receiving power.
