1. Introduction

This User Guide is intended to provide application support for the ADV7604 evaluation

kit. It also provides details on the set up and manual configuration of the evaluation

board. Software drivers are available for this evaluation board - a separate user guide is

available for these software drivers.

2. Evaluation Kit

Each ADV7604 evaluation kit consists of the following:

ADV7604 Evaluation Board

ATV Motherboard

Video Output Module

USB cable

7.5V DC power supply module

Evaluation kit CD

3. Initial Configuration

3.1 Hardware

The ATV evaluation platformis comprised of three modules the ADV7604 evaluation

board, the ATV motherboard and the video output module. To assemble the evaluation

platform, plug the ADV7604 evaluation board into the Female AV Input connector ofthe

motherboard and plug the videooutput module into the Male AV Output connector of

the motherboard.

Connect the female connector of the 7.5V DC power supply module supplied with the

evaluation kit to the motherboard power connector, J18. Connect the USB cable supplied

with the evaluationkit to the motherboardUSB connector, J12.

The evaluation platformshould now resemble Figure 1.

To turn the evaluation platform on, flick motherboard power switch (S10)to position

light 2 3 seconds later. This indicates the eval platform is now readyto use.

3.2 Software

3.2.1 ATV Benchtop Installation

All the files necessary to install the ATV Benchtop software are on the evaluation kit CD

supplied in the evaluation kit. To install the ATV Benchtop software from the evaluation

kit CD, please complete the following steps:

Copy the ATV Benchtop installer folder to the c:\ drive.



Follow the installationwizard to complete installation following the onscreen

instructions including a restart if prompted.

Please note; to install the ATV Benchtop software, you need to be an administrator on the

PC the software is being installed on.

3.2.2 Getting Started with ADV Register Control Software

The ADV RegisterControl software can be usedto run example configuration scripts on

the ATV Evaluation platform and adjust I2C register settings via USB. In order to launch

the ADV Register Control software from the ATV Benchtop, complete the following

steps:

Launch the ATV Benchtop from -> All

Programs -> Analog Devices -> ATV Benchtop -> ATV Benchtop). The ATV

Benchtop control panel as per Figure 2 will appear.

Figure 2 –ATV Benchtop Control

Select ADV Register Control from the ATV Benchtop control panel.

Select a script targeting the device on your evaluation platform (ADV7604 in this

case) from the ADV Register Program Configuration window as per Figure 3.

4.1.1 Connecting Input Video

To connect an input video source to the evaluation board, use a suitable cable and one of

the input video connectors outlined above. Do not use excessive force when connecting

or disconnecting the cables as this may result in damage to the evaluation board.

4.1.2 EDID Configuration

There are two EDID options availableto user on the ADV7604 board an external

PROM on port D to which an EDID can be programmed or an internal EDID PROM

within the ADV7604.

4.1.2.1 Configuring the External EDID

To program the external PROM (U10) for port D, complete the following procedure:

Connect the PROMto the I2C bus by puttingjumpers K7 and K8into position B

Connect the evaluation platform to the asoutlined in Section 3

The EDID is now downloaded the external PROM. Reset the jumpers to position

A to use the external EDID

4.1.2.2 Configuring the Internal EDID

To program the internal PROM, complete the following procedure:

Disconnect the external EDID by removing jumpers K7 and K8

Select the EDID script from the Settings -> Scripts menu in the ADV Register

Control Panel

Note: the external EDID PROMs are not stuffed for ports A, B or C. If it is desired to stuff

these parts, please consult the evaluation board BOM for details of the required parts.

4.1.3 Powerdown Mode EDID

To evaluation the powerdown mode EDID, the evaluation board should be disconnected

from the powered ATV motherboard. A HDMI cable with an activesource supplying 5V

to the HDMI 5V line should be connected.

The user can then determine whether they want the SPI PROM EDID replicated on ports

A, B, C and Dor ports A, B, andC by inserting orremoving the SE_PIN header

respectively.

The user can alsodisconnect the 5V supply from a source plugged into port Dby

removing jumper SE_PWR.

4.3 UsingConfigurationScripts

The evaluation platform is provided with a set of scripts to provide a fast and easy means

of configuring the system to process a wide variety of input video formats. Figure 4

illustrates how a specific script file can be accessed and selected from the ADV Register

Control Panel (e.g. Setting -> Scripts -> DESIRED CATEGORY -> DESIRED SCRIPT).

indication box. Registermaps can be accessed fromthe ADV Register ControlPanel by

clicking on the tabs across the screen below the standard toolbar (e.g. DEVICE 1,

DEVICE 2). The selected register map name is displayed when the tab is selected.
