LatticeECP2M™ SERDES Evaluation Board User’s Guide May 2010 Revision: EB25_01.7 LatticeECP2M SERDES Evaluation Board User’s Guide Lattice Semiconductor Introduction This user’s guide describes the LatticeECP2M™ SERDES Evaluation Board featuring the LatticeECP2M FPGA. This stand-alone evaluation PCB provides a functional platform for development and rapid prototyping of applications that require high-speed SERDES interfaces. The board also includes a PCI Express x1 edge for future expansion. Please note the PCI Express x1 edge is only connected if the board is populated with the LatticeECP2M-50 or larger FPGA. The evaluation board includes provisioning to connect four high-speed SERDES channels via SMA connectors to test and measurement equipment. 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 customer evaluations of the LatticeECP2M FPGA. The intended use of this guide is to be referenced in conjunction with evaluation design tutorials to demonstrate the LatticeECP2M FPGA. Figure 1.

LatticeECP2M SERDES Evaluation Board, Top View 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 LatticeECP2/M Family Data Sheet. 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. However, only the LFE2M50E-FF672 device allows full use of the PCI Express x1 edge, SFP and SATA interfaces. Applying Power to the Board The LatticeECP2M SERDES 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 2) 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 to use with a bench-top supply adjusted to provide a nominal 12V DC. All input power sources and on-board power supplies use surface mounted fuses and have green LEDs to indicate power GOOD status of the intermediate supplies 4 LatticeECP2M SERDES Evaluation Board User’s Guide Lattice Semiconductor Table 1.

This interface allows the user to provide power from a PCI Express Host board. Programming/FPGA Configuration (see Appendix A, Figure 4) A programming header is provided on the evaluation board, providing access to the LatticeECP2M JTAG port. Note: An ispDOWNLOAD® Cable is included with each ispLEVER design tool shipment. Cables may also be purchased separately from Lattice. ispVM Download Interface J8 is an 10-pin JTAG connector used in conjunction with the ispVM USB download cable to program and control the device. 5 LatticeECP2M SERDES Evaluation Board User’s Guide Lattice Semiconductor Table 4. ispVM JTAG Connector (see Appendix A, Figure 2) Pin 1 VCC Pin 2 TDO Pin 3 TDI Pin 4 PROGRAMN Pin 5 NC Pin 6 TMS Pin 7 GND Pin 8 TCK Pin 9 DONE Pin 10 INITN Programming Daisy Chain This board includes two Lattice Semiconductor 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}. Also a jumper 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 only to program U1, J105 requires jumpers across pins{1-2} and pins{3-5}. J10 requires only a jumper across pins{1-2}. Download Procedures Requirements • PC with ispVM System v.16.0 (or later) programming management software, installed with appropriate drivers (USB driver for USB Cable, Windows NT/2000/XP parallel port driver for ispDOWNLOAD Cable). Note: An option to install these drivers is included as part of the ispVM System setup. • ispDOWNLOAD Cable (HW-DLN-3C, HW-USBN-2A, etc.) 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. 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. 6 LatticeECP2M SERDES Evaluation Board User’s Guide Lattice Semiconductor 1. Press the SCAN button located in the toolbar. The LatticeECP2M device will automatically be detected. 2. Double-click the device to open the device information dialog. In the device information dialog, click the Browse button located under Data File. Locate the desired bitstream file (.bit). Click OK to both dialog boxes. 3. Click the green GO button. This will begin the download process into the device. Upon successful download, the device will be operational. 7 LatticeECP2M SERDES Evaluation Board User’s Guide Lattice Semiconductor Configuration Status Indicators (see Appendix A, Figure 4) These LEDs indicate the status of configuration to the FPGA. • D8 (red) illuminated – Indicates that programming was aborted or reinitialized, driving the INITN output low. • D11 (green) illuminated – Indicates the successful completion of configuration by releasing the open collector DONE output pin. • D12 (green) flashing – Indicates TDI activity. • D10 (red) illuminated – Indicates that PROGRAMN is low. • D9 (red) illuminated – Indicates that GSRN is low. PROGRAMN and GSRN (see Appendix A, Figure 4) 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 4) 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 4) 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 is supplied 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 8) The evaluation board includes various features for generating and managing on-board clocks. The clocks are generated from input provided via SMAs (see Table 5) 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. A 4-pin DIP type oscillator such as the Connor-Winfield XO-400 series can be used in socket Y1. Both of these input clock sources are routed through the Lattice ispClock5620A programmable clock manager devices (U2). These clock management devices allow for clock synthesis and buffering. 8 LatticeECP2M SERDES Evaluation Board User’s Guide Lattice Semiconductor Table 5. SMA Clock Input SMA Signal J35 U2 Reference + Input J36 U2 Reference - Input U2 is an ispClock5620A clock generator that allows designers to implement clock distribution networks supporting multiple, synchronized output frequencies using a single device. 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 for download from the Lattice web site at www.latticesemi.com/pac-designer) 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 does not need to be 50%; the only requirement is that both the HIGH and LOW times of this signal must be 1.25ns 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. 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 that control 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 a 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 5). The board has various component stuffing options to provision specific clock source variations. Table 6 outlines the need to open or short connections on the board as well as required terminations for proper signal quality. Table 6.

This device drives clocks to both SERDES quads via 100-ohm LVDS signaling. The on-board clock oscillators mentioned in previous sections of this document can be chosen to drive the same SERDES reference clocks. In addition, the board can be provisioned to source the clock from the PCI Express edge-fingers directly to the SERDES REFCLK pins. SERDES Channels Surface Mounted SMA Connections (see Appendix A, Figure 5) DC coupled top-mounted SMA connectors connect to the four SERDES Tx and Rx channels. These pins are directly coupled to the designated SMA connector, creating a path for both input and output differential data. Table 7.
