Board Components & Interfaces
Power Supply The power supply block distributes clean power to the Stratix II GX
device. You can either power-up using an on-board regulator or an
external power supply. This section provides the following board power
information:
■ Power supply for each component
■ Components attached to each power rail
■ Power distribution system
Power Supply for Each Component
Table 2–35 shows the board’s power specifications per component.
