MAX9276A/MAX9280A
Evaluation Kits
Evaluate: MAX9276A/MAX9280A
General Description
The MAX9276A/MAX9280A coax evaluation kits (EV
kit) provide a proven design to evaluate the MAX9276A/
MAX9280A high-bandwidth gigabit multimedia serial link
(GMSL) deserializers with spread spectrum and full-
duplex control channel with the use of a standard FAKRA
coaxial cable. 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 device. The EV kit comes
with a MAX9276A or MAX9280A installed.
For complete GMSL evaluation, using a standard FAKRA
coaxial cable, order the MAX9276A/MAX9280A coax EV
kit and a companion serializer board (MAX9275/MAX9279
coax EV kit referenced in this document). For evaluating
with STP cable, also order the MAXCOAX2STP-HSD
adapter kit and refer to its data sheet. Only one adapter kit
is required per link, connecting the serializer and deserial-
izer (SerDes) boards.
Ordering Information
appears at end of data sheet.

MAX9276A/MAX9280A coax EV kit (USB cable
included)
MAX9275/MAX9279 coax EV kit (USB cable
included)
2m Rosenberger FAKRA cable assembly (included
with the deserializer EV kit)
Parallel data source (such as digital video)
Optional: Function generator (needed only if parallel
data lacks a pixel clock)
User-supplied Windows XP, Windows Vista, or
Windows 7 PC with a spare USB port (direct 500mA
connection required; do not use a bus-powered hub)
5V DC, 500mA power supply
6)
Evaluate: MAX9276A/MAX9280A
Connect the FAKRA cable from the serializer EV kit
OUT+ connector to the deserializer EV kit IN+ con-
nector.
Connect the parallel data source to the serializer EV
kit headers (H1_DIN28:0).
Connect pixel clock or function generator to the serial-
izer EV kit header (H1_PCLK_IN).
Turn on power supply and function generator.
7)
8)
9)
10) Verify that LED_PWR on the serializer EV kit turns on,
indicating that the board has power.
11) Verify that LED_D2 on the deserializer EV kit turns
on, indicating that the microcontroller is powered and
enabled.
12) Verify that LED_LOCK on the deserializer EV kit lights
up, indicating that the link has been successfully
established. If LED_LOCK is off or LED_ERROR is
on, double-check that the PCLK_IN signal is clocking
data.
13) Start the EV kit software by selecting
Start | Pro-
grams | Maxim Integrated | MAXSerDesEV-D |
MAXSerDesEV-D.
The
Configuration Settings
win-
dow will appear (Figure
1).
Jumper settings in this
window are for user reference and guide to properly
configure the evaluation board. Jumper settings do
not force the serializer or deserializer into a particular
mode of operation.
14)
UART mode support: To configure for UART
mode, on the deserializer board, change jumpers
JU_I2CSEL from H to the L position. On the serializer
board, change jumpers JU_CONF1 and JU_CONF0
as shown in the
Serializer
group box, JU_TXSCL
from SCL to the TX position, and JU_RXSDA from
SDA to the RX position.
15) Press the
Identify Devices
button to have the GUI
scan the bus for possible listeners. In case no device
was identified, the most likely cause is improper jump-
er settings. Identify the problem before continuing.
16) Press the
Connect
button to launch the
Evaluation
Kit
window (Figure
2).
17) Press the
Read All
button to read all registers on the
deserializer and serializer.

3)
4)
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
Download and install the EV kit software from
www.maximintegrated.com/EVkitsoftware.
Install the appropriate USB driver for your PC from
the links provided.
Verify that all jumpers are in their default positions, as
shown in
Table 1.
With the power supply and function generator off,
connect the 5V power supply to the +5VIN terminal
pad on the serializer EV kit.
Connect the USB cable from the PC to the deserial-
izer EV kit (J10). A Windows message appears when
connecting the EV kit board to the PC for the first
time. Each version of Windows has a slightly different
message. If you see a Windows message stating
ready to use,
then proceed to the next step; other-
wise, open the USB_Driver_Help_200.PDF to verify
that the USB driver was successfully installed.

Evaluation Kits
Detailed Description of Software
Evaluate: MAX9276A/MAX9280A
Controller Group Box
In the
Controller
group box, select
Coax
or
STP
from
the
LinkType
drop-down list,
I2C
or
UART
from the
Bus
drop-down list, and whether the
Serializer
or
Deserializer
should connect to the USB controller. Upon
changing any of these parameters, any conflicting jumper
settings will be highlighted, guiding the user to check
and make the corresponding changes to the evaluation
boards. Only
LinkType
and
Device Address
selections
on the
Configuration Settings
window affect the EV kit
operation. Other items, including jumper selection, are for
user reference only.
To start the MAX9276A/MAX9280A deserializer coax EV
kit GUI, select
Start | Programs | Maxim Integrated |
MAXSerDesEV-D | MAXSerDesEVGUI-D.
Configuration Settings
The
Configuration Settings
window is the first window
that opens after program launch. It allows the user to
specify evaluation board setup and mode of operation.

Serializer and Deserializer Jumper Selection
Blocks
The
Serializer Jumper Selection
and
Deserializer
Jumper Selection
blocks list jumpers for the selected
Device IDs
and displays the correct shunt positions based
on the conditions selected in the
Controller
group box.

Evaluation Kit Window
The
Evaluation Kit
window shown in
Figure 2
provides
access to all internal functions of the DUTs by means
of reading and writing registers through different tabs to
allow the user to evaluate various functions of the SerDes.
The
Read All
button updates the SerDes’ device maps by
reading the DUT’s internal registers.
The
Serializer
group box provides pushbuttons to access
the serializer’s registers. The
Read all MAX9279
button
reads register contents from the serializer and updates
the displayed register values. The
Load
button reads and
updates registers from a previously saved register map
file or saves the existing register values into a new file for
future reference using the
Save
button.
The
Deserializer
group box provides pushbuttons
to access the deserializer’s registers. The
Read All
MAX9280/80A
button reads register contents from the
deserializer and updates the displayed register values.
The
Load
button reads and updates registers from a
previously saved register map file or saves the existing
register values into a new file for future reference using
the
Save
button.
The
Open Configuration
button opens the
Configuration
Settings
window for any configuration change. Use
Open Configuration
and
Connect
buttons to go back
and forth between
Configuration Settings
window and
Evaluation Kit
window.
The
Wake Up
button applies the register write sequence
described in the IC data sheets to wake the DUTs from
sleep mode.
Identify Devices Button
The
Identify Devices
button causes the GUI to scan the
system and hunt for slave addresses selectable by the
SerDes input address pins. Upon successful communi-
cation, the identified
Device ID
and the corresponding
jumper lists are displayed on the serializer and deserial-
izer block. It is also possible to manually select a device
from the list in the
Device ID
drop-down list and enter
the slave address in the
Device Address
edit box. It is a
good practice to utilize the
Identify Devices
function and
verify communication with the devices under test (DUTs)
before attempting to
Connect.
Figure 9
and
Figure 10
show jumper settings on the
SerDes PCBs for coax cable and I
2
C communication
with the USB controller connected to the deserializer
board. Refer the respective deserializer IC data sheet for
detailed configuration information. See
Table 1
for PCB
jumper descriptions.
Connect Button
The
Connect
button opens up the
Evaluation Kit
win-
dow. The GUI reads the SerDes registers and updates the
register maps for both. Successful register map updates
are indicated by green LED indicators. In case of a com-
munication problem, the LED indicators turn red.
Cancel - Do not Connect Button
The
Cancel - Do not Connect
button opens the
Evaluation Kit
window without attempting to connect to
the on-board microcontroller. Although there will be no
communication with the microcontroller, all functions and
tabs corresponding to the selected
Device IDs
become
active once there.

lists the serializer’s bitmaps.
The
Read
and
Write
buttons in each register group box
allow read/write access for each bit or group of bits that
specify a function or condition, as defined in the serializer
Evaluate: MAX9276A/MAX9280A
IC data sheet. The color of the small LED indicator next
to the
Read/Write
buttons indicates the communication
status. Green indicates successful communication and
red indicates failed communication.
