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
