Functional Operating Voltage Range – 650 MHz
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. SPI-4 reference should be derived from VCC25V so that they track fluctuations in VCC25V.
4. The tolerance on the PCI supply is tighter than specified in the PCI Local Bus Specification, Version 2.2*.
