Introduction
The ADV7180 is available in three packages, 64-pin LQFP, 40-pin LFCSP and 32-pin
LFCSP. The EVAL-ADV7180LFEBZ employs the 40-pin LFCSP packaged decoder, the
EVAL-ADV1780LQEBZ employs the 64-pin LQFP packaged decoder, and the EVAL-
ADV7180-32EBZ employs the 32-pin LFCSP packaged decoder. This application note
is intended to provide application support for the ADV7180 evaluation boards. This
document contains a description of the evaluation kit and the evaluation boards. It also
provides details on setup and configuration for evaluation.
Evaluation Kit
Each ADV7180EB evaluation kit consists of the following:
•ADV7180 Evaluation board
•ADV7180 Evaluation Kit CD
•I2C Download cable with USB port connector.
•7V DC Power Supply Module.
Initial Configuration.
Register Control Software
1. Install the Register Control software from the evaluation CD. (Please refer to the
Installation Guide on the evaluation CD for step-by-step instructions.)
2. Once the software is installed, power up the board and connect the USB
connector.
3. Start the application (START>PROGRAM>.ADVREGISTER CONTROL
>ADVREGISTER CONTROL 3.56).
The ADV Register Program Configuration screen appears, as shown in Figure 1

4. Ensure the options are set, as shown in Figure 1, and click on the OK button.
When the register control software starts, it firstly initializes all the selected
devices and then loads the reset defaults for each device. I2C control and reset
signals are connected to the evaluation board through the USB cable. This cable
should be connected to the evaluation board before the application software is
started.
Configuring ADV7180 Modes Using Script Files
To enable easy and efficient evaluation, the ADV Register Control software is provided
with script files that can be used to program the evaluation board’s decoder and encoder
into preset configurations. Figure 2 illustrates how a script file can be accessed and
selected from the drop down menu

Board-Level Description.
There is an evaluation board for each package type. The primary features of the boards
and their positions are marked in
Figure 3, Figure 4 and Figure 5.
Do not connect CVBS, S-Video, YPrPb simultaneously when using the EVAL-
ADV7180LFEBZ and the EVAL-ADV7180-32EBZ, as they share the three analog
inputs to the decoder. Please refer to Figure 9 and Figure 19 in the schematics section of
this document.
