DESCRIPTION
Quick Start
Recommended Equipment
• MAX9526 EV kit (USB cable included)
• User-supplied Windows 2000/XP- or Windows Vista-
compatible PC with a spare USB port
• 5V, 500mA DC power supply
• Video signal generator (e.g., Tektronix TG-2000 or
similar)
• Component analog or parallel/serial digital video
measurement equipment
• Component analog video monitor
Note:
In the following sections, software-related items
are identified by bolding. Text in
bold
refers to items
directly from the EV kit software. Text in
bold and
underlined
refers to items from the Windows operating
system.
3) Verify jumper settings (see Table 1).
4) Connect external 5V, 500mA power supply to
banana jacks P1 (+) and P2 (-) and verify that
jumper JU1 is in the 1-2 position.
5) Connect the output of the video signal generator to
the IN1A RCA connector on the MAX9526 EV kit.
6) Connect the H1 header from the EV kit to an ITU-
compatible bit-parallel interface measurement
equipment.
7) Optionally, connect component video monitor to the
U/BLUE, Y/GREEN, and V/RED BNC connectors
from the EV kit.
8) Set the video signal generator for the desired AC-
coupled PAL or NTSC video input signal.
9) Turn on the power supply and enable the video sig-
nal generator.
10) Connect the USB cable from the PC to the EV kit
board. A
Building Driver Database
window pops
up in addition to a
New Hardware Found
message
when installing the USB driver for the first time. If a
window is not seen that is similar to the one
described above after 30s, remove the USB cable
from the board and reconnect it. Administrator privi-
leges are required to install the USB device driver
on Windows.
11) Follow the directions of the
Add New Hardware
Wizard
to install the USB device driver. Choose the
Search for the best driver for your device
option.
Specify the location of the device driver to be
Procedure
The MAX9526 EV kit is fully assembled and tested.
Follow the steps below to verify board operation.
Caution: Do not turn on the power supply until all
connections are completed.
1) Visit
www.maxim-ic.com/evkitsoftware
to down-
load the latest version of the EV kit software,
9526Rxx.ZIP. Save the EV kit software to a tempo-
rary folder and uncompress the ZIP file.
2) Install the EV kit software on your computer by run-
ning the 9526Rxx.msi program inside the temporary
folder. The program files are copied and icons are
created in the Windows
Start | Programs
menu.

(default installation
directory) using the
Browse
button. During device
driver installation, Windows may show a warning
message indicating that the device driver Maxim
uses does not contain a digital signature. This is not
an error condition and it is safe to proceed with
installation. Refer to the USB_Driver_Help.PDF doc-
ument included with the software for additional
information.
12) Start the MAX9526 EV kit software by opening its
icon in the
Start | Programs
menu, then press the
Reset to Default Values
button. The EV kit software
main window appears, as shown in Figure 1.
13) Analyze the video output signal.
Detailed Description of Software
The MAX9526 EV kit software provides a graphical user
interface (GUI) to configure the EV kit hardware. Three
devices are controlled by the I
2
C interface bus:
MAX9526 (U1), MAX4586 (U5), and ADV7176A (U6).
The status bar indicates MAX9526
IRQ
output pin status.
Drop-down lists select the I
2
C device address for
MAX9526, MAX4586, and ADV7176A. The
ITU Demux
Address
drop-down list includes both ADV7175A and
ADV7176A device addresses. Each of these address
selection drop-down lists include an option to search
known addresses for each corresponding device (see
Figure 1).

Figure 2. Advanced User Interface Window
MAX9526 Video Decoder Tab
Registers 0x00 and 0x01 are read-only status displays.
All the other registers have
Read
and
Write
buttons.
The
Read All
and
Write All
buttons read or write all the
MAX9526 device registers. The
Reset to Default
Values
button allows writing all the MAX9526 device
registers to their default state.
Advanced User Interface
The
Options | Interface (Advanced Users)
menu item
brings up the
Advanced User Interface
window shown
in Figure 2. This window allows sending arbitrary com-
mands on the I
2
C bus.
Configuration File Format
Register configuration can be saved to a file and later
reloaded by the software. From the
File
menu, select
either the
Load Configuration File
or the
Save
Configuration File As…
menu item. The MAX9526
read-only status registers (0x00 and 0x01) are saved
but not restored when configuration is loaded. The
MAX4586 device (U5) saves the channel selection from
the software GUI. The ITUDEMUX device (U6) saves
only four of its registers (0x00, 0x01, 0x07, and 0x0D).
Any registers added by manually editing the configura-
tion file are not checked for data integrity.
MAX4586 Video Input Multiplexer Tab
The
MAX4586 Video Input Multiplexer
tab sheet has a
set of five radio buttons, selecting IN1 = IN1A, IN1B,
the unconnected input pins, or nothing.
Note:
The EV
kit hardware does not connect all MAX4586 inputs.
ITU Demultiplexer Tab
The
ITU Demultiplexer
tab sheet controls the
ADV7176A MODE0, MODE1, and MODE2 registers.
Interface History Tab
The
Interface History
tab sheet provides a list of the
I
2
C and other commands generated by the on-board
microcontroller.
