LatticeECP2M PCI Express x4
Evaluation Board - Revision A User’s Guide
Introduction
This user’s guide describes the LatticeECP2M PCI Express x4 Evaluation Board featuring the LatticeECP2M
FPGA device. The evaluation board has been designed to support the LatticeECP2M35 device and the
LatticeECP2M50 device. Different versions of the evaluation board are available that contain either the
LatticeECP2M35 device or the LatticeECP2M50 device. The stand-alone evaluation PCB provides a functional
platform for development and rapid prototyping of applications that require high-speed SERDES interfaces to PCI
Express protocols.
The evaluation board includes provisioning to connect high-speed SERDES channels via SMA connectors to test
and measurement equipment. Please note that boards populated with the LatticeECP2M-35 device have all available SERDES channels routed to the PCI Express, and in this case the SMAs are not active. The SMAs are available in larger density LatticeECP2M FPGAs fitting the same footprint, but with additional SERDES channels. The
board is manufactured using standard FR4 dielectric and through-hole vias. The nominal impedance is 50-ohm for
single-ended traces and 100-ohm for differential traces.
The board has several debugging and analyzing features for complete user evaluation of the LatticeECP2M device.
This guide is intended to be referenced in conjunction with evaluation design tutorials to demonstrate the
LatticeECP2M FPGA.
This document describes boards marked with “Rev A” on the PCB silkscreen, next to the Lattice logo. For boards
marked “Rev B”, refer to the LatticeECP2M PCI Express x4 Evaluation Board - Revision B User’s Guide.

application by consulting documentation provided by Lattice. Differences in component selection and/or PCB layout
in the user's application may significantly affect circuit performance and reliability.
LatticeECP2M Device
This board features a LatticeECP2M FPGA with a 1.2V core supply. It can accommodate all pin compatible
LatticeECP2M devices in the 672-ball fpBGA (1mm pitch) package. A complete description of this device can be
found in the LatticeECP2M Family Data Sheet on the Lattice web site at www.latticesemi.com.
Note: The connections referenced in this document refer to the LFE2M35E-FF672 device. Available I/Os and associated sysIO™ banks may differ for other densities within this device family. For example, only the LFE2M50EFF672 device allows full use of the high speed SERDES test SMAs and SMPTE BNC connections.
Applying Power to the Board
The LatticeECP2M PCI Express x4 Evaluation Board is ready to power on. The 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 terminal 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 J1 and plug the wall transformer into an AC wall outlet.
Power Supplies
(see Appendix A, Figure 7)
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 provided for use with a bench top supply adjusted
to provide a nominal 12V DC.

Programming Daisy Chain
This board includes two Lattice programmable devices that can be programmed in a daisy chain. A jumper setting
of J105 controls the chain. Both devices are in the programming chain from the JTAG header, J8, with jumpers on
J105 across Pins{1-2}, Pins{3-4}, and Pins{5-6}. Jumpers on J10 across Pins{1-2} and Pins{3-4} are also required
for both devices to be in the chain.
If the user desires to only program U1, J105 requires jumpers across Pins{1-2} and Pins{4-6}. J10 requires only a
jumper across Pins {1-2}.
Download Procedures
Requirements:
• PC with ispVM System v.16.1.2 (or later) programming management software, installed with appropriate drivers
(USB driver for USB Cable, Windows NT/2000/XP parallel port driver for ispDOWNLOAD Cable). The latest
ispVM System software can be downloaded from the Lattice web site at www.latticesemi.com/ispvm.
Note: An option to install these drivers is included as part of the ispVM System setup.
• ispDOWNLOAD Cable (HW-DLN-3C, HW-USBN-2A, or equivalent)
JTAG Download
The LatticeECP2M device can be configured easily via its JTAG port. The device is SRAM-based; it must remain
powered on to retain its configuration when programmed in this fashion.
1. Connect the ispDOWNLOAD Cable to the appropriate header. J8 is used for the 1x10 cable.
Important Note: The board must be un-powered when connecting, disconnecting, or reconnecting the ispDOWNLOAD Cable. Always connect the ispDOWNLOAD Cable's GND pin (black wire), before connecting any
other JTAG pins. Failure to follow these procedures can in result in damage to the LatticeECP2M FPGA device
and render the board inoperable.
2. Connect the LatticeECP2M Evaluation Board to the appropriate power sources and power up board.
3. Start the ispVM System software.

Configuration Status Indicators
(see Appendix A, Figure 8)
These LEDs indicate the status of configuration to the FPGA.
• D8 (RED) illuminated, this indicates that the programming was aborted or reinitialized driving the INITN output
low.
• D11 (GREEN) is illuminated, this indicates the successful completion of configuration by releasing the open collector DONE output pin.
• D12 (GREEN) will flash indicating TDI activity.
• D10 (RED) illuminated, this indicates that PROGRAMN is low.
• D9 (RED) illuminated, this indicates that GSRN is low.
PROGRAMN and GSRN
(see Appendix A, Figure 8)
These push-button switches assert/de-assert the logic levels on the PROGRAMN (SW3) and GSRN (SW2).
Depressing the button drives a logic level “0” to the device.
CFG [2:0]
(see Appendix A, Figure 8)
The FPGA CFG pins are set on the board for a particular programming mode via the SW1 DIP switch. JTAG programming is independent of the MODE pins and is always available to the user
On-Board Flash Memory
(see Appendix A, Figure 8)
Two memory devices (U10 and U12) are on-board for non-volatile configuration memory storage. These two
devices occupy the same Flash slot on the board. U10 can be populated with an 8M or smaller 8-pin SOIC device.
U12 can be used in place of U10 with a 16-pin TSSOP 64M Flash device. U15 always supplies as an 8M Flash
device. J11 is used to control the selection of the Flash memory to be accessed.
FPGA Clock Management
(see Appendix A, Figure 12)
The evaluation board includes various features for generating and managing on-board clocks. The clocks are generated from either input provided from SMAs (see table below) or from crystal oscillators (Y1 and Y2). Y1 is socketed for interchangeability and Y2 is a 100MHz surface-mounted oscillator which is fanned out around U1 for
reference clocks with a fan-out buffer IC.
Y1 can be a 4-pin DIP type oscillator like the Connor-infield XO-400 series.
Both of these input clock sources are routed through the Lattice ispClock5620A devices (U2). These programmable
clock management devices allow for clock synthesis and buffering.

U2 Reference - Input
U2 is a Lattice ispClock5620A in-system programmable analog circuit that allows designers to implement clock distribution networks supporting multiple synchronized output frequencies using a single integrated circuit. By integrating a Phase-Locked Loop (PLL) along with multiple output dividers, the ispClock5620A can derive up to five

separate output frequencies from a single input reference frequency. PAC-Designer® software (available from the
Lattice web site at www.latticesemi.com/pacdesigner) is used to program the ispClock features.
ispClock supports reference clocks in the range of 10 to 320 MHz. The duty cycle of the clock source need not be
50%; the only requirement is that both the HIGH and LOW times of this signal must be 1.25 ns or longer. The following standards are supported with either minimal or no external components: LVTTL, LVCMOS, SSTL2, SSTL3,
HSTL, LVDS and LVPECL.
When the ispClock5620A is in a LOCKED state, the LOCK output pin goes LOW. The LOCKN pins are connected
to amber LED D13 and will illuminate when the LOCKN pin goes low. The lock detector has two operating modes:
phase lock mode and frequency lock mode. In phase lock mode, the LOCK signal is asserted if the phases of the
reference and feedback signals match, whereas in frequency lock mode the LOCK signal is asserted when the frequencies of the feedback and reference signals match.
U2 is controlled by SW4 or from a predefined connection to U1 (LatticeECP2M). The DIP switch controls the ispClock device. The reference clock selection and device reset is controlled using the switches. The switches controlling the ispClock outputs can be synchronously controlled by the SGATE output on a bank-by-bank basis or tristated on an output-by-output basis using the OEXb and OEYb inputs. All outputs may be tri-stated by bringing the
GOEb input high.
The VCCO voltage is board-connected to 2.5V or 3.3V based on the on-board connection of FB21 or FB22.
The output clocks of U2 are routed to devices to provide system level clocking. These pre-defined board clocks are
routed to input LatticeECP2M input clock pins for SERDES reference clocks, primary clocks, PLL inputs and DLL
inputs as well as connection to an SMA (J34). This SMA is 50-ohm terminated for off-board interconnection to test
equipment.
A clock input to the ispClock device can be provided from the PCI Express edge fingers. This is accomplished by
configuring the on-board resistor jumpers R79 and R80 (see Appendix A, Figure 9).
SERDES
(see Appendix A, Figure 9)
SERDES Reference Clock
The 50-ohm terminated SMA connectors are provided to supply reference clocks directly to the LatticeECP2M
device from the ispClock management device. This device drives clocks to both SERDES quads via 100-ohm
LVDS signaling. On-board clock oscillators mentioned in the previous sections can be chosen to drive the same
SERDES reference clocks. The board can also be provisioned to source the clock from the PCI Express edge fingers directly to the SERDES REFCLK pins.
SERDES Channels
Note: Surface Mounted SMA Connections are only available for the LFE2M50E-FF672 device.
(see Appendix A, Figure 9)
DC coupled top-mounted SMA connectors connect to the three SERDES Tx and Rx channels of the L-Quad SERDES. These pins are directly coupled to the designated SMA connector creating a path for both input and output
differential data.
