Power
c
The Stratix PCI development board can be powered up from one of the
following sources:
The +2.5-, +1.5-, and +1.25-V power OK LEDs require the -12.0-V supply
to illuminate. These LEDs only illuminate when the PCI connector J11 or
power connector J18 supplies power to the board.
An LCD display installed at J5 and J19 requires +5.0 and +12.0 V to
operate. The LCD display only operates when the PCI connector J11 or the
power connector J18 supplies power to the board.
+2.5-V Regulators
The board contains two voltage regulators that generate +2.5 V from the
+3.3 V power for DDR SDRAM memory and the HSDI interfaces. The two
voltage regulators U4 and U5 operate in parallel to supply the current
required by the +2.5 V supply. Amplifier U9 equalizes the current flowing
through U4 and U5 by monitoring and matching the current flowing
through the resistors R13 and R15. See

PCI connector J11 supplies +3.3, +5.0, +12.0, and -12.0 V.
Power connector J18 supplies +3.3, +5.0, +12.0, and -12.0 V from the
external power adaptor cable plugged into an optional PC ATX
power supply.
HSDI port A connector J13 supplies +3.3 V.
HSDI port B connector J8 or J9 supplies +3.3 V.
The board has special power supply circuitry that can be
damaged if more than one power source is applied to the board
at the same time.
