3) Verify jumper settings (see Table 1).
Quick Start
Recommended Equipment
• MAX9526 EV kit (USB cable included)
4) Connect external 5V, 500mA power supply to
banana jacks P1 (+) and P2 (-) and verify that
jumper JU1 is in the 1-2 position.
• User-supplied Windows 2000/XP- or Windows Vista-
compatible PC with a spare USB port
5) Connect the output of the video signal generator to
the IN1A RCA connector on the MAX9526 EV kit.
• 5V, 500mA DC power supply
6) Connect the H1 header from the EV kit to an ITU-
compatible bit-parallel interface measurement
equipment.
• Video signal generator (e.g., Tektronix TG-2000 or
similar)
• Component analog or parallel/serial digital video
measurement equipment
7) Optionally, connect component video monitor to the
U/BLUE, Y/GREEN, and V/RED BNC connectors
from the EV kit.
• Component analog video monitor
8) Set the video signal generator for the desired AC-
coupled PAL or NTSC video input signal.
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.
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.
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.
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
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.

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.
Detailed Description of Software
The MAX9526 EV kit software provides a graphical user
interface (GUI) to configure the EV kit hardware. Three
2
devices are controlled by the I C interface bus:
MAX9526 (U1), MAX4586 (U5), and ADV7176A (U6).
The status bar indicates MAX9526 IRQ output pin status.
2
Drop-down lists select the I 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).
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.

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.

The MAX4586 Video Input Multiplexer tab sheet has a
set of five radio buttons, selecting IN1 = IN1A, IN1B,

Analog Reconstruction DAC
U6 (ADV7176A) reconstructs the digital ITU-R BT.656
bit-parallel interface signals into component analog
video output. U7 (MAX9584) buffers and filters the DC-
coupled outputs U/BLUE, Y/GREEN, and V/RED.
Detailed Description of Hardware
The MAX9526 EV kit is a fully assembled and tested
surface-mount PCB that contains a MAX9526 IC. The
MAX9526 is a low-power, high-performance multistan-
dard video decoder.
Serial Digital Output Option
Optional U8 (CLC021AVGZ) converts the parallel digi-
tal ITU-R BT.656 bit-parallel interface signals into differ-
ential serial digital output (SDO).
External passive video switch U5 (MAX4586) allows
evaluation of recovery from asynchronous external mul-
tiplexer switching. LDO linear regulator U3 (MAX8511)
powers the MAX9526 1.8V digital and analog supplies.
LDO linear regulator U4 (MAX1658) supplies 3.3V to
the rest of the board. Low-voltage TTL buffer U2
(74AVC16244) drives the 3.3V ITU-R BT.656 bit-parallel
interface-compatible signals on header H1. Header H2

User-Supplied 3.3V Power Supply
The MAX9526 EV kit requires a USB connection to
power the on-board microcontroller. When directly con-
nected to a high-power (500mA) USB host, move the
shunt of JU1 to the 2-3 position to power the EV kit 3.3V
and 1.8V LDO linear regulators (U4 and U3) from USB.
Input Coupling
The MAX9526 EV kit inputs IN1A, IN1B, and IN2 are
AC-coupled.
Output Coupling
The MAX9526 EV kit drives DC-coupled analog video
reconstruction outputs from the ADV7176A (U6).
When used with a low-power (100mA) USB host, such as
a hub, power the 3.3V MAX1658 LDO linear regulator
from an external 500mA power supply. Move the shunt of
JU1 to the 1-2 position to apply your own 4.8V to 16.5V
DC power supply at the P1 (EXT PWR) banana jack.
