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.
