1. Introduction
The Lattice Semiconductor CrossLink™-NX Evaluation Board allows designers to investigate and experiment with the
features of the CrossLink-NX Field Programmable Gate Array (FPGA). The features of the CrossLink-NX Evaluation Board
can assist engineers with the rapid prototyping and testing of their specific designs.
The CrossLink-NX Evaluation Board is part of the CrossLink-NX Evaluation Kit, which includes the following:

CrossLink-NX Evaluation Board pre-loaded with the shipping demo design

12 V AC/DC power adapter and international plug adapters

Lattice Radiant® Software license information

USB-A to USB-B (Mini) Cable for programming FPGA through a PC

Quick Start Guide
The contents of this user guide include top-level functional descriptions of the various portions of the development
board, descriptions of the on-board headers, diodes and switches and a complete set of schematics.
1.1. CrossLink-NX Evaluation Board
The CrossLink-NX Evaluation Board features the CrossLink-NX FPGA in the 400-ball caBGA package (LIFCL-40-9BG400C)
w the ability to expand the usability of the CrossLink-NX with Raspberry Pi, PMOD, FMC LPC connector, along with
access to PCIe channel. 118 wide range I/O and 37 high speed differential pairs are available for user-defined
applications.
