Overview

This document presents the steps to setup an environment for using the EVAL-CN0178-SDPZ

evaluation board together with the Xilinx KC705 FPGA board and the Xilinx Embedded Development

Kit (EDK). Below is presented a picture of the EVAL-CN0178-SDPZ Evaluation Board with the Xilinx

KC705 board.

For component evaluation and performance purposes, as opposed to quick prototyping, the user is

directed to use the part evaluation setup. This consists of:

1. A controller board like the SDP-B ( EVAL-SDP-CS1Z)

●

2. The component SDP compatible product evaluation board

●

3. Corresponding PC software ( shipped with the product evaluation board)

●

The SDP-B controller board is part of Analog Devices System Demonstration Platform (SDP). It

provides a high speed USB 2.0 connection from the PC to the component evaluation board. The PC

runs the evaluation software. Each evaluation board, which is an SDP compatible daughter board,

includes the necessary installation file required for performance testing.

Note: it is expected that the analog performance on the two platforms may differ.

The CN0178 circuit uses the ADL5902 TruPwr™ detector to measure the rms signal strength of RF

signals with varying crest factors (peak-to-average ratio) over a dynamic range of approximately 65

dB and operates at frequencies from 50 MHz up to 9 GHz.

The measurement result is provided as serial data at the output of a 12-bit ADC (AD7466).

The ADL5902 is a true rms responding power detector that has a 65 dB measurement range when

driven with a single-ended 50 O source. This feature makes the ADL5902 frequency versatile by

eliminating the need for a balun or any other form of external input tuning for operation up to 9 GHz.

The ADL5902 provides a solution in a variety of high frequency systems requiring an accurate

measurement of signal power. Requiring only a single supply of 5 V and a few capacitors, it is easy to

use and capable of being driven single-ended or with a balun for differential input drive. The ADL5902

can operate from 50 MHz to 9 GHz and can accept inputs from -62 dBm to at least +3 dBm with large

crest factors, such as GSM, CDMA, W-CDMA, TD-SCDMA, WiMAX, and LTE modulated signals.

The AD7466 is 12-bit, high speed, low power, successive approximation analog-to-digital converter

(ADC). The part operates from a single 1.6 V to 3.6 V power supply and feature throughput rates up to

200 kSPS with low power dissipation. The part contains a low noise, wide bandwidth track-and-hold

amplifier, which can handle input frequencies in excess of 3 MHz.

The EVAL-CN0178-SDP board contains the circuit to be evaluated, as described in this note. To

power the EVAL-CN0178C-SDP evaluation board supply +6V between the +6 V and GND inputs.

Run the Demonstration Project

Hardware setup

Before connecting the ADI evaluation board to the Xilinx KC705 make sure that

the VADJ_FPGA voltage of the KC705 is set to 3.3V. For more details on how to

change the setting for VADJ_FPGA visit the Xilinx KC705 product page.

Use the FMC-SDP interposer to connect the ADI evaluation board to the Xilinx KC705 board on the

●

FMC LPC connector.

Connect the JTAG and UART cables to the KC705 and power up the FPGA board.

Reference Project Overview

The following commands were implemented in this version of EVAL-CN0178 reference project for

Xilinx KC705 FPGA board.

Command Description

help? Displays all available commands.

calibration=

Makes a four points calibration. Accepted values:

power input1(lowest value):

-60 .. 0 - first point input power in [dBm].

power input2:

-60 .. 0 - second point input power in [dBm].

power input3:

-60 .. 0 - third point input power in [dBm].

power input3(highest value):

-60 .. 0 - fourth point input power in [dBm].

pinCalc? Displays the calculated input power in [dBm].

error? Displays the error associated with the last input power calculation. Accepted values:

-60 .. 0 - true input power in [dBm].

Commands can be executed using a serial terminal connected to the UART peripheral of Xilinx KC705

FPGA.

The following image shows a generic list of commands in a serial terminal connected to Xilinx KC705

FPGA's UART peripheral.

Software Project Setup

The hardware platform for each reference projects with FMC-SDP interposer and KC705 evaluation

board is common. The next steps should be followed to recreate the software project of the reference

design:

First download the KC705 Reference project from Github on your computer. You can do this by

●

clonning this repository: https://github.com/analogdevicesinc/fpgahdl_xilinx.

From this entire repository you will use cf_sdp_kc705 folder. This is common for all KC705 projects.

●

Rev 15 Nov 2013 12:50 | Page 7

Open the Xilinx SDK. When the SDK starts, it asks you to provide a folder where to store the

●

workspace. Any folder can be provided. Make sure that the path where it is located does not contain

any spaces.

In the SDK select the File→Import menu option to import the software projects into the workspace.

●

In the Import window select the General→Existing Projects into Workspace option.

●

In the Import Projects window select the cf_sdp_kc705 folder as root directory and check the Copy

●

projects into workspace option. After the root directory is chosen the projects that reside in that

directory will appear in the Projects list. Press Finish to finalize the import process.

Rev 15 Nov 2013 12:50 | Page 8

The Project Explorer window now shows the projects that exist in the workspace without software

●

files.

Now the software must be added in your project. For downloading the software, you must use 3

●

links from Github given in Downloads section. From there you'll download the specific driver, the

specific commands and the Xilinx Boards Common Drivers(which are commons for all Xilinx boards).

All the software files downloaded must be copied in src folder from sw folder.

Before compilation in the file called Communication.h you have to

●

uncomment the name of the device that you currently use. In the picture below

there is an example of this, which works only with AD5629R project. For another

device, uncomment only the respective name. You can have one driver working

on multiple devices, so the drivers's name and the uncommented name may

not be the same for every project.

Rev 15 Nov 2013 12:50 | Page 9

The SDK should automatically build the project and the Console window will display the result of the

●

build. If the build is not done automatically, select the Project→Build Automatically menu option.

If the project was built without any errors, you can program the FPGA and run the software

●

application.
