1. DESCRIPTION OF THE ADV7281-M EVALUATION BOARD

Analog video is fed into the analog inputs (Ain1 to Ain6) of the ADV7281-M evaluation board. The ADV7281-M evaluation board can be

configured to receive many different analog video formats (refer to Table 1 ). The analog video from analog inputs is fed into the

ADV7281-M video decoder which converts it into a MIPI CSI-2 output stream.

The MIPI CSI-2 output of the ADV7281-M consists of one differential data lane (D0+ and D0-) and one differential clock lane (Clk+ and

CLk-). These are output to the SMA connectors on the evaluation board.

Note: The shaded areas in Table 1indicate that modifications need to be made to the ADV7281-M evaluation board before that particular

video input standard can be input to that particular analog input pin.

evaluation board.

evaluation board.

[3] These inputs can be configured to receive YC (S-video), but the user needs to change some resistor values on the ADV7281-M

evaluation board.

[4] These inputs can be configured to receive component (YPbPr), but the user needs to change some resistor values on the ADV7281-M

evaluation board.

2. SETTING UP THE ADV7281-M EVALUATION BOARD

The Analog Devices (ADI) DVP Eval program and ADV7281-M script files are needed to operate the ADV7281-M evaluation board. The

DVP Eval program and ADV7281-M script files are available on an ADI File Transfer Protocol (FTP) site.

The following setup process is recommended, and is described in detail in Section 2.1 to Section 2.6.

1. Download and install an FTP client.

2. Download the DVP Eval program and ADV7281-M script files from the ADI FTP site.

3. Install the DVP Eval program.

4. Load the ADV7281-M script files.

5. Power up the ADV7281-M evaluation board.

6. Program the ADV7281-M evaluation board.

2.1.DOWNLOAD AND INSTALL AN FTP CLIENT

Download and install an FTP client such as FileZilla in order to access the ADI FTP site.

1. Go to the http://filezilla-project.org/download.php?type=client website.

2. Download the FileZilla FTP client .exe installation file.

3. When the download is completed, run the .exe installation file and follow the onscreen instructions.

2.2.DOWNLOAD ADV7281-M FILES FROM ADI FTP SITE

The DVP Eval program and ADV7281-M script files are available on the ADI FTP site.

1. Open the FTP client, for example, FileZilla.

2. A quick connect bar appears near the top of the FileZilla client window. Enter the following information. (Note that the boxes

are case sensitive.)

a. In the Host box, enter ftp.analog.com.

b. In the Username box, enter adv728x.

c. In the Password box enter1dN62jy.

d. Leave the Port box blank.

3. Press the Quickconnect button.

FileZilla then shows two panes (refer to Figure 2). The left pane displays the Local Site Pane (that is, your computer). The right

pane displays the Remote Site Pane (that is, the ADI FTP site).

4. On the Local Site Pane, navigate to where you want to drop the ADV7281-M files.

5. On the Remote Site Pane, select the ADV7281-M folder.

Note: Do not select the ADV7281-MA folder.

6. Drag the ADV7281-M folder to the desired location in the Local Site Pane.

7. Drag the Install DVP Eval Latest Source 10-14-11.exe installation file to the desired location in the Local Site Pane.

The files and folders on the ADI FTP site then copy to your computer.

Note: The Transfer Queue Pane shows the progress of this copying.

2.3.INSTALL THE DVP EVAL PROGRAM

1. When the transfer from the FTP site is complete (as described in Section 2.2), double click on the Install DVP Eval Latest

Source 10-14-11.exe file.

2. A window appears showing a software license agreement. After you have read the agreement, press the I Agree button.

3. A new window appears asking if you want to add Desktop and Start Menu shortcuts. Press the Next button.

4. A new window appears (refer to Figure 3), prompting you to select the installation destination folder. Press the Install button.

Note: It is strongly recommended to use the default destination folder. Selecting a different folder can cause the DVP Eval

program to not install correctly in some versions of Windows.

3. Copy the folder called ADV7281M_CUST to the following directory:

C:\Documents and Settings\USER_NAME\My Documents\Analog Devices\DVP Eval Latest Source 10-14-11\xml\New Boards.

Note: This directory may be slightly different depending on where you installed the DVP Eval program.

4. To open the DVP Eval program, select Start -> Analog Devices -> DVP Eval Latest Source 10-14-11.

5. Select File -> Update Boards.

Figure 4. Update Board Files on DVP Eval Program

A number of black command prompt windows appear and then disappear. Finally, a window appears with the message “update

boards successful”. Press the OK button.

The ADV7281-M script files have been added to the DVP Eval program.

6. Exit the DVP Eval program.

2.5.POWER UP THE ADV7281-M EVALUATION BOARD

1. Connect a mains cable to the 7.5 V supply cable included in the ADV7281-M evaluation kit.

2. Connect the 7.5 V supply cable to Jumper J8 on the ADV7281-M evaluation board. When this is done correctly, LED D6 turns

on (refer to Figure 1).

3. Connect the USB cable included in the ADV7281-M evaluation kit to the computer where you installed the DVP Eval program

and ADV7281-M script files. This cable is used to send commands from your computer to the ADV7281-M evaluation board.

4. Connect the other end of the USB cable to Jumper J7 of the ADV7281-M evaluation board. When this is done correctly, LED D7

turns on (refer to refer to Figure 1).

5. Connect the analog video input(s) to the Ain inputs of the ADV7281-M evaluation board. Refer to Table 1 for information on

how to connect these inputs.

6. Connect SMA cables to the MIPI CSI-2 output connectors and feed these to a sink device.

Notes:

•The I2C lines to the ADV7281-M can be accessed via test points on the evaluation board. Refer to Figure 1.

•Even after the ADV7281-M evaluation board is powered up, the 28.63636 MHz crystal (Y1) will not oscillate until the

ADV7281-M is programmed (refer to Section 2.6).

2.6.PROGRAM THE ADV7281-M EVALUATION BOARD

1. To run the DVP Eval Latest Source application, select Start-> All Programs -> Analog Devices -> DVP Eval Latest Source 10-14-

11.

2. Press the Choose Board button on the top left of the DVP Eval program window and the Board Selector window appears (refer

to Figure 5).

Figure 5. Board Selector Window of DVP Eval Program

3. Select ADV7281M_CUST in the Rx section of the Board Selector window.

4. Select None in the MotherBoard section.

5. Select None in the Tx section.

6. Press the Load button. A window similar to that shown in Figure 6 appears.
