Processor 9500
Series
The Intel
®
Itanium
®
Processor 9500 Series implements a Serial VID BUS that is used
to transfer power management information between the microprocessor and the five
output voltages. Voltage levels are compliant to the VR12.0 1V TTL signaling
requirements and are shown in Table 2-32.
2. With input leakage current measured at the pin with 0V and with 1.1 V supplied to the pin. System designers
are advised to check the tolerance of their voltage regulator solutions to ensure a voltage of 1.1 V at the pin.
