External Power Supply Requirements
This section describes the different external power supplies required to power
Cyclone IV devices. Table 11–1 and Table 11–2 list the descriptions of external power
supply pins for Cyclone IV GX and Cyclone IV E devices, respectively.
f For each Altera recommended power supply’s operating conditions, refer to the
Cyclone IV Device Datasheet chapter.
f For power supply pin connection guidelines and power regulator sharing, refer to the
Cyclone IV Device Family Pin Connection Guidelines.
