MAX9268 Evaluation Kit
General Description
The MAX9268 evaluation kit (EV kit) provides a proven
design to evaluate the MAX9268 gigabit multimedia
serial link (GMSL) with spread spectrum and full-duplex
control channel. The EV kit also includes Windows XP
®
-,
Windows Vista
®-
, and Windows
®
7-compatible software
that provides a simple graphical user interface (GUI) for
exercising the features of the MAX9268.
The MAX9268 EV kit comes with a MAX9268GCM/V+
installed.
For complete GMSL evaluation, order both the MAX9268
EV kit and its companion board, the MAX9249 EV kit or
the MAX9259 EV kit.

Procedure
8)
Visit
www.maxim-ic.com/evkitsoftware
to download
the latest version of the EV kit software, 9268Rxx.
ZIP. Save the EV kit software to a temporary folder
and uncompress the ZIP file.
Install the EV kit software and USB driver on your
computer by running the INSTALL.EXE program
inside the temporary folder. The program files are
copied to your PC and icons are created in the
Windows
Start | Programs
menu. During software
installation, some versions of Windows may show
a warning message indicating that this software
is from an unknown publisher. This is not an error
condition and it is safe to proceed with installation.
Administrator privileges are required to install the
USB device driver on Windows.
9)
2)
10) Verify that MAX9268 EV kit LED2 lights up, indicat-
ing that the link has been successfully established.
If LED2 is off or LED1 is on, double-check that
PCLK_IN signal is clocking data.
11)
Optional Audio Demo:
Press and release switch
SW122 on both of the MAX9249 and MAX9268 EV
kits to enable the S/PDIF-to-I

that MAX9268 INT input is asserted.
25) In the software’s
MAX9268
tab, scroll to
Register 0x06
and press the
Read
button. Verify
that the
INT
checkbox is checked, indicating that
MAX9268 INT input is asserted.
26) Toggle MAX9268 EV kit switch SW2 down. Verify
that MAX9249 EV kit LED1 turns off, indicating that
MAX9268 INT input is not asserted.
27) In the software’s
MAX9268
tab, scroll to
Register 0x06
and press the
Read
button. Verify
that the
INT
checkbox is not checked, indicating
that MAX9268 INT input is not asserted.
Detailed Description of Software
The main window of the evaluation software (Figure 1)
shows a block diagram representing the MAX9249/
MAX9268 system. The left column shows MAX9249 input
data sources, and the right column shows MAX9268
output data sinks.
The
Change Configuration
button (Figure 1) brings
up the
Configuration
window (Figure 7), allowing the
software GUI to select into which side of the link the
USB cable should be plugged. Controlling from the
MAX9268 side requires changing some jumper set-
tings as described in this window. If the MAX9249
and MAX9268 device addresses have been previously
changed from their factory power-on-reset values, the
new addresses must be specified in the
Configuration
window to allow register access.
The
Baud Rate
drop-down list sets the communications
baud rate. The USB link uses the same baud rate as the
MAX9249/MAX9268. Note that the baud rate should only
be changed one step at a time.
The
Read All
button reads all the MAX9249 and
MAX9268 device registers.
Reset to Default Values
restores recommended factory settings, and
Write All
writes all MAX9249/MAX9268 device registers with the
values shown in the GUI.
The
MAX9249
tab sheet (Figure 2) provides direct access
to all registers of the MAX9249, and the
MAX9268
tab
sheet (Figure 3) provides direct access to all registers of
the MAX9268. Each register has its own
Read
and
Write
button. The small circle next to the
Read
button turns yel-
low to indicate an attempt to read or write, red to indicate
a failed read or write, and green to indicate a successful
read or write operation.
The
MAX7324
tab sheet (Figure 4) controls the I
2
C I/O
expander on the remote side of the link. When the USB
is plugged into the MAX9249 EV kit, the
MAX7324
tab
sheet controls the MAX7324 (U15) on the MAX9268
EV kit. Note that the MAX7324 actually has two device
addresses; for simplicity, the software GUI only displays
the device address associated with MAX7324 outputs.
For details, refer to the MAX7324 IC data sheet.
The
PRBS Test
tab sheet (Figure 5) uses the MAX9268
registers to perform a pseudorandom bit sequence
(PRBS) error-rate test. Select the test duration (maxi-
mum 32,767sec = 9.1hrs) and press the
Start
button.
The software GUI configures the MAX9268 to begin the
PRBS test, counts down the specified delay time, and
then reports the final value of the MAX9268 PRBSERR
register.
