Functional Operating Voltage Range – 1.4/1.0 GHz
1. These supplies can be derived from core Vcc, but should be filtered appropriately.
2. QDR references should be derived from Vddq so that they track fluctuations in Vddq.
3. During power-up, after NRESET is de-asserted, the device will experience an increase in current consumption after the PLL
4. SPI-4 reference should be derived from VCC25V so that they track fluctuations in VCC25V.
5. The tolerance on the PCI supply is tighter than specified in the PCI Local Bus Specification, Version 2.2*.

locks and the system clocks begin to operate at full speed. During this time a droop on the core power supply may occur due
to this increase in current consumption. It is acceptable that the core power supply droop a maximum of 100 mV to a minimum
of 1.2 V during this time. It is expected that the device be Idle during this time and that no instructions be executing until the
power is within the 5% regulation specification. The behavior is undefined if instructions are executed while the power is not
within the 5% regulation specification.
