Introduction

This document describes the Pentek Model 7858 Dual 500−MHz A/D, 800−MHz D/A PCI Express tion, and installation steps.

(PCIe®) board, its associated software, what to consider before installa−

Before You Begin: Description of Hardware

Pentek’s Model 7858 is a multichannel, high−speed data converter suitable for connec− tion to HF or IF ports of a communications system. Using the PCI Express (PCIe) half− length card format, it includes two A/Ds and two D/A converters, dual Virtex−5 FPGAs, and two banks of DDR2 SDRAM.

The Model 7858 consists of one Pentek Model 7158 PMC/XMC module mounted on a Pentek Model 78010 or 78011 PMC/XMC PCI Express carrier, assembled and tested as a single board. It is ready to plug into computer boards with PCIe bus slots.

Refer to the Pentek Model 7158 Operating Manual (800.71580) for a complete description of the 7158 hardware operation and programming.

Before You Begin: Consider the Host Bus Characteristics

When you install the Model 7858, you will need to set jumpers and switches and con− sider installation options based on the characteristics of the host bus. Therefore, you will need to know the bus mode of operation and bus speed (MHz). You will also need to know whether the XMC connector (Option 5xx) will be used.

Option 5xx for the Model 7858 provides an XMC connector that complies with the VITA 42.0 XMC Switched Mezzanine Card Auxiliary Standard. This standard provides two 4x 2.5 GHz data links between the XMC and the baseboard. Three options are available for the XMC reference clock:

• Option 520 provides a 156.25−MHz reference clock.

• Option 521 provides a 125−MHz reference clock.

• Option 522 provides a 100−MHz reference clock.

To preview the jumper and switch settings you’ll need to consider, refer to Chapter 2 of the Pentek Model 7858 Installation Manual (800.78580). The PMC module jumpers control PCI/PCI−X bus operation, XMC Lane 0 path, and FLASH memory protect. The PCIe carrier jumpers control power sequencer enable, XMC MVMRO, SM bus enable, and PMC ID select. The PCIe carrier switches control PMC PCI/PCI−X modes and XMC serial data routing.

Before You Begin: Description of Software

Board Support Software for the Pentek Model 7858 PCIe Board

Pentek’s ReadyFlow® Board Support Packages (BSP) contain software support for the

Model 7858 PCIe board. This includes a device driver for the 7858, plus the ReadyFlow Board Support Library data structures and routines. The following available BSPs allow high−level programming for various workstation platforms. Refer to the User’s Guide indicated for each platform:

• Model 4994A Option 156 ReadyFlow BSP for Linux® (816.71560)

• Model 4995A Option 156 ReadyFlow BSP for Windows

• Model 4996A Option 156 ReadyFlow BSP for VxWorks

Pentek’s ReadyFlow® Board Support Libraries contain a set of C−language routines for the Model 715x. Refer to the Programmer’s Reference for the Model 7156 (801.71561).

(815.71560)

(813.71560)

NOTE: The Model 7156 ReadyFlow software package is used for both the Model 7156

and Model 7158 modules.

Software for the FPGAs

The FPGA is supported with a Pentek GateFlow® FPGA Design Kit. The GateFlow Design Kit (Model 4953−158 Options −083, −084, −085, and −087) facilitates user− installed FPGA functions using the Xilinx ISE Foundation tool suite. The FPGA Design Kit allows you to modify, add to, or replace the default logic functions within the FPGA with functions of your own definition.

Note that GateFlow is a very specialized software package intended for users with experience in FPGA logic programming. This package may not be required if your application needs are met with the Pentek−default FPGA code.

Refer to the following GateFlow software documentation: Pentek Model 4953−158−083/

084/085/087 User’s Manual: Design Kit for the Processing FPGA on the Model 7158 PMC/ XMC Dual A/D & D/A Converter (807.71580).

Before You Begin: Consider the Product’s Options

Timing and Synchronization

The following timing and synchronization options are available for the Pentek Model 7858 module’s A/D and D/A converters:

• Internal timing buses: Two internal timing buses provide either a single clock or two different clock rates to the A/D and D/A signal paths. Each timing bus includes a clock, sync, and a gate or trigger signal. An internal clock generator receives an external sample clock from the front panel SMC connector (labeled EXT CLK). This clock can be used directly for either the A/D or D/A sections or can be divided by a built−in clock synthesizer circuit to provide different A/D and D/A clocks. The external clock signal must be a sine wave of +2 dBm to +6 dBm, with a frequency range from 10 to 200 MHz. This input is enabled using the Master Bus Control Register RF2 & RF1 SEL bits (see the Pentek Model 7158 Operating Manual).

• Onboard crystal oscillator: Alternately, the sample clock can be sourced from an onboard voltage−controlled crystal oscillator (VCXO). In this mode, the front panel SMC connector (labeled EXT CLK) can be used to provide a 10 MHz reference clock for synchronizing the internal oscillator.

• 26−pin sync bus front panel connector: This connector (labeled SYNC) allows multiple modules to be synchronized. In the slave mode, it accepts LVPECL inputs that drive the clock, sync, PPS, and gate signals. In the master mode, the LVPECL bus can drive the timing signals for synchronizing multiple modules. Up to four Model 7158 boards can be driven from the LVPECL bus master, supporting synchronous sampling and sync functions across all connected boards. The mating 26−pin connector is Pentek part # 353.02607 (ERNI # 214346). For a description of the SYNC connector pin configuration, refer to the Pentek Model 7158 Operating Manual.

FPGAs

The Model 7858 includes one 7158 PMC module that has two Xilinx Virtex−5 FPGAs for signal interfaces and processing:

• Processing FPGA − Provides signal translation, processing, and time delay functions.

• PCI Interface FPGA − Provides board interfaces, including PCI−X.

Following are FPGA considerations:

• Supported Processing FPGAs: The Processing FPGA can be populated with a

variety of different FPGAs to match the specific requirements of the processing task. Supported FPGAs include:

• Standard (Option 084) − XC5VSX50T

• Option 083 − XC5VLX155T

• Option 085 − XC5VSX95T

• Option 087 − XC5VFX100T

• Supported PCI Interface FPGAs:

• Standard (Option 090) − XC5VLX30T

• Option 093 − XC5VSX50T

• FPGA I/O through the P14 Connector (Option 104): Option −104 adds the P14 PMC

connector with 16 pairs of LVDS connections to the Processing FPGA and 16 pairs of LVDS connections to the Interface FPGA for custom I/O. For more information, refer to Section 2.7.4 in the Pentek Model 7858 Installation Manual.

• Heat Sinks (Option 73x): Because the 7158 series can have complex programming in

large FPGAs, the power dissipation can exceed 30W. Because of this, Pentek provides several two−slot heat sink options with superior cooling capabilities relative to the standard, single−slot heat sink. The following heat sink options are available.

• Option 730 − heat sink with no fan

• Option 731 − heat sink with 5V fan

• Option 732 − heat sink with 12V fan

• JTAG Expansion Assembly: The Model 9269 JTAG expansion assembly provides

several LEDs and connectors, which provide access to both FPGAs for JTAG functions, and access to the PowerPC in the Processing FPGA for Ethernet and RS232 I/O. The Model 9269 is usually just plugged into the J1 connector on the 7158 PCB. However it is also possible to mount the JTAG board permanently to the 7158 PCB. Call Pentek for further details. For more information about the JTAG assembly, refer to Section 2.5 of the Pentek Model 7158 Operating Manual (800.71580).

Step 1: Unpacking and Inspecting the Unit

After unpacking, inspect the unit carefully for possible damage to connectors or com− ponents. Refer to page 3 for a list of what should be in the box. If anything is missing or damaged, contact Pentek immediately at (201) 818−5900. Please save the shipping container and packing material in case reshipment is required.

Step 2: Checking the Jumper and Switch Settings

At the factory, all jumpers and switches on the Model 7858 are installed in default positions. The default parameters selected may or may not meet your requirements. As described above in jumpers and switches are set based on the characteristics of the host bus.

Before installing your Model 7858, review Chapter 2 in the Model 7858 Installation Manual to determine whether you need to change any settings.

Before You Begin: Consider the Host Bus Characteristics, the

NOTE: If you need to access the jumpers or switches on the PCIe carrier, you must

first remove the PMC module from the PCIe carrier, as described in Section

2.2.1 of the Model 7858 Installation Manual.

NOTE:

You should only change the jumpers that are described in the Model 7858 Installation Manual − all others are reserved for factory test and setup

purposes.

Step 3: Installing the Hardware

The Model 7858 is designed to operate in personal computers that provide PCI Express (PCIe) card slots. To install the Model 7858, follow the procedure in Section 2.8 (Installing the Model 7858 in a Personal Computer) in the Pentek Model 7858 Installation Manual.

NOTE: When the Option 73x heat sink is mounted on the Model 7858 PCB, the overall

size of the board extends 1.3737 inches (34.89 mm) from the baseboard or carrier (measured from the PMC standoff to the edge of the heat sink). Note that this configuration will require a second slot in most PC chassis. For more information, refer to Section 2.8.2 in the Pentek Model 7858 Installation Manual (800.78580).

Step 4: Installing the Cabling

Connect a cable for each input and output your application requires to the Model 7158 PMC front panel SMC microminiature coaxial connectors. These are labeled CH 1 and CH 2 IN: one for each ADC input channel, and CH 1 and CH 2 OUT: one for each DAC output channel. The other cabling you install on the Model 7158 PMC front panel depends on how you want to handle timing and synchronization (see chronization). Multiple modules can be synchronized via the 26−pin sync bus connec− tors (SYNC) using a ribbon cable. The bus format is compatible with other Pentek PMC modules and can be used with Pentek’s Clock/Sync Distribution Amplifier products for creating larger, multi−channel systems.

NOTE: When connecting LVPECL Sync Bus pins to additional 7158 PMC modules,

the LVPECL pins on the LAST unit must be terminated. Pentek includes a terminating board, part # 002.71504, with your shipment for this purpose.

Note that if you transfer a new configuration for the Virtex−5 FPGAs on the Model 7158, you will use a Xilinx download cable as described in Sections 2.3 and 2.4 of the Pentek Model 4953−158−083/084/085/087 User’s Manual (807.71580).

GateFlow FPGA Design Kit

The following software and hardware is required to use the GateFlow FPGA Design Kit:

• Xilinx’s Foundation ISE (Version 11.4 or later − the design kit was produced using

ISE Project Navigator Release 11.4).

• Xilinx’s Platform Cable: To connect to your development computer system you will

need one of the following two cables, purchased from Xilinx:

• Parallel Cable IV (Model DLC7, Xilinx part # HW−PC4)

• Platform Cable USB (Model DLC9, Xilinx part # HWUSB−G)

The Parallel Cable IV has two connectors at one end that both connect to your com− puter system, one to the ECP−enabled Parallel port (you may need to check this port setting in your BIOS) and the other, a 5V supply connection, may be inserted between your mouse or keyboard and its PS/2 port, or simply plugged into one of those ports if your mouse and keyboard connect via USB.



The Platform USB cable connects to a USB port on your development computer system, and thus carries its own 5V supply connection.



The other end of both cables terminates in a pod, which contains a shrouded con− nector for a 14−pin, 2 mm pitch ribbon cable. The ribbon cable is included with the shipment of both Xilinx programming cables.

To install the FPGA Design Kit for the Model 7158 module’s Processing FPGA, copy the

\GateFlow folder on the DVD−ROM to the root directory of the C: drive of the system

you’ll be working on.

Rev. C

Page 12

Page 12 Pentek Model 7858 Getting Started Guide

GateFlow FPGA Design Kit (continued)

The directory structure of the GateFlow DVD−ROMs mimics that of the development system upon which the original projects were created. We recommend that you copy

\GateFlow folder on each DVD−ROM to the root directory of the C: drive of the sys−

the tem you’ll be working on, such that the original, absolute pathnames of all files in the included project are maintained.

NOTE: Many of the files in the included project folders reference the absolute

pathnames of other files in the same project. If you copy the GateFlow project

to a different directory, then you can expect problems when the Project Navigator interface is unable to locate the “missing” (i. e., differently−named) files.

Full details for installing the FPGA Design Kit are provided in Chapter 1 of the Gate− Flow user manual listed in Documentation Required for Installation.

Step 6: Using the Software

ReadyFlow Software

Chapter 3 of the User’s Guide for each ReadyFlow BSP provides instructions for using the ReadyFlow software:

• Introduction to ReadyFlow − Provides an overview of how the software is used.

• Using ReadyFlow − Provides details about using ReadyFlow, along with a modified code snippet from the 7156

• DMA Setup and Usage − Describes the DMA engine, how to set up DMA transfers for either a single transfer or multiple transfers, and how to set up an interrupt to signal the end of a DMA transfer.

• ReadyFlow Documentation − Describes how the ReadyFlow package descriptions are organized in the Programmer’s Reference Guide.

GateFlow FPGA Design Kit

Chapter 2 of the GateFlow User Manual covers procedures for implementing a project:

example program.

• Using Your GateFlow FPGA Design Kit with Xilinx’s Foundation ISE Software

• Preparing for a New FPGA Configuration

• Transferring Configuration Data to the Model 7158

GateFlow FPGA Design Kit (continued)

The GateFlow FPGA Design Kit includes test bench files and simulation projects that functionally simulate many operations of the Model 7158, when the FPGAs are config ured with their factory default configurations. Details are provided in Chapter 3 of the GateFlow User Manual (see

We recommend that before attempting any operational modifications of the default FPGA design, you should become very familiar with the board’s performance when operated with the default design. Once you are comfortably familiar with the default operation, we recommend that your first project with the FPGA design kit should be to re−compile the default code with one very simple change (the contents of the read− only FPGA Revision registers), and re−configure the FPGA with the re−compiled con figuration file. (Refer to Chapter 2 of the GateFlow User Manual for details.)

If you discover that you can use the entire default design for the FPGA, and simply need to add another function or two, the tables in Chapter 1 of the GateFlow User Man ual will help you to determine how much of the FPGA’s resources remain available for your use.
