LatticeECP3 PCI Express Solutions Board – Revision A
Lattice Semiconductor
User’s Guide
Introduction
As PCI Express applications have emerged, the LatticeECP3™ FPGA family has become a well-suited solution for
many system designs. The features of the LatticeECP3 PCI Express Solutions Board can assist engineers with
rapid-prototyping and testing their designs. The board is an enhanced form-factor of the PCI Express add-in card
specification. It allows for full x1 form-factor compliance and x4 is available for demonstration purposes with some
non-standard form-factor issues. The flexibility to use the same board to demonstrate both x1 and x4 configurations
is accomplished by simply changing the mounting hardware. The board has several debugging and analyzing fea-
tures for complete evaluation of the LatticeECP3 device. This guide is intended to be referenced in conjunction with
evaluation design tutorials to demonstrate the LatticeECP3 FPGA.
This user’s guide describes the LatticeECP3 PCI Express Solutions Board featuring the LatticeECP3 LFE3-95EA-
FN672 FPGA. The stand-alone evaluation board provides a functional platform for development and rapid prototyp-
ing of applications that require high-speed SERDES interfaces to demonstrate PCI Express capabilities using an
add-on card form-factor. The board is manufactured using standard FR4 dielectric and through-hole vias. The nom-
inal impedance is 50-ohm for single-ended traces and 85-ohm for differential traces.
Important: This document (including the schematics in the appendix) describes LatticeECP3 PCI Express Solu-
tions Boards marked as Rev A. This marking can be seen on the silkscreen of the printed circuit board, under the
