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.

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

programmed
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.
