LatticeECP3 Device
This board features a LatticeECP3 FPGA with a 1.2V core supply. It can accommodate all pin compatible
LatticeECP3 devices in the 1156-ball fpBGA (1mm pitch) package. A complete description of this device can be
found in the
Applying Power to the Board
The LatticeECP3 Video Protocol Board is ready to power on. This board can be supplied with power from an AC
wall-type transformer power supply shipped with the board. Or it can be supplied from a bench top supply via termi-
nal screw connections. It also has provisions to be supplied from the PCI Express edge fingers from a host board.
To supply power from the factory-supplied wall transformer, simply connect the output connection of the power cord
to J15 and plug wall-transformer into an AC wall outlet.
Supply Power from Bench Power Supply
The evaluation board incorporates an alternate scheme to provide power to the board. The board is equipped to
accept a main supply via the TB1 connection. This connection is intended to be used with a bench top supply
adjusted to provide a nominal 12V DC.
All input power sources and on-board power supplies are fused with surface mounted fuses. Table 1 shows these
fuses and the corresponding powers.

on the board. There are six LEDs used to indicate the status of the monitoring voltages. If the monitoring voltage is
not in the +/- 5% voltage window, the corresponding LED will flash; otherwise, the LED will stay ON. Table 2 shows
these six voltages and the corresponding LEDs.
