Evaluates: MAX96705/MAX96711
with Coax or STP Cable
MAX96705/MAX96711
Evaluation Kit
General Description
The MAX96705/MAX96711 coax evaluation kit (EV kit)
provides a proven design to evaluate the MAX96705 and
MAX96711 high-bandwidth gigabit multimedia serial link
(GMSL) serializers with spread spectrum and full-duplex
control channel, through the use of a standard FAKRA
coax or STP cable. The EV kit also includes Windows
Vista
®
- and Windows 7-compatible software that provides
a simple graphical user interface (GUI) for exercising
features of the device. The EV kit comes with either a
MAX96705GTJ+ or MAX96711GTJ+ IC installed.
For complete GMSL evaluation using a standard FAKRA
coax cable, order the MAX96705 or MAX96711 EV kit
and a companion deserializer board (the MAX96706 or
MAX96708 EV kit are referenced in this document). For
testing 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 deserializer boards).
Note: In the following sections, MAX96705/11 and the
term “serializer” refer to the MAX96705 or MAX96711 ICs
and MAX96706/08 and the term “deserializer” refer to the
MAX96706 or MAX96708 ICs.
Note: This document applies to both coax and STP EV
kits. This document covers coax cables, but the informa-
tion provided applies equally to STP cables.
Features
● Accepts 16-Bit Parallel Input Data and Outputs
GMSL Serial Data through FAKRA Connectors
● Windows Vista-, and Windows 7-Compatible
Software
● USB-Controlled Interface (Cable Included)
● USB Powered
● Proven PCB Layout
● Fully Assembled and Tested

Quick Start
Required Equipment
● MAX96705 or MAX96711 serializer EV kit
● MAX96706 or MAX96708 deserializer EV kit
● 2m FAKRA cable assembly (included with the
deserializer EV kit)
● > 20MHz function generator
● PC with Windows Vista or Windows 7 and a spare
USB port (direct 500mA connection required; do not
use a bus-powered hub)
● 5V DC, 500mA power supply
Note: In the following sections, software-related items are
identified by bolding. Text in bold refers to items from the
EV kit software. Text in bold and underlined refers to
items from the Windows operating system.
Procedure
The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
1) Visit www.maximintegrated.com/EVkitsoftware to
download and install the latest version of the EV kit
software:
● Search for MAX9288. Then select MAX9288 |
Design Resources | Software | GMSL SerDes
Evaluation Kit Software-Nuvoton.
● The installation application will try to download
and install the USB driver for the Nuvoton micro-
controller. If the USB driver installation was not
successful, install the appropriate USB driver for
your PC available from the link below, and refer
to the USB_Driver_Help_200.PDF file, if needed:
www.ftdichip.com/Drivers/VCP.htm.
2) Verify that jumpers on the serializer board are in their
default positions, as shown in Figure 14.
3) Verify that jumpers on the deserializer board are in
their default positions, as shown in Figure 15.
4) Set up the system, as shown in Figure 1.
5) Connect the FAKRA cable from the OUT+ termi-
nal on the serializer board to the IN0+ terminal
on the deserializer board. Both the serializer and
deserializer evaluation boards have power-over-coax
(POC) circuitry that is active by default, congured
such that the deserializer board is the source of the
power for the serializer board.
6) Connect the USB cable between the PC and USB
port on the Nuvoton microcontroller daughter board
on the serializer board.
7) Verify that LED_PWR on the deserializer board lights
up, indicating that the deserializer board has power.
8) Verify that LED_PWR on the serializer board lights
up, indicating that the serializer board has power.
Both serializer and deserializer have a power-over-
coax (POC) circuit that is active by default.
9) Verify that LOCK_LED on the deserializer
board lights up, indicating that the link has been
successfully established. If the LOCK_LED is
off, or ERR_LED is on, go to the Troubleshoot-
ing section and x the problem before continuing.
Note: If you are working with an earlier version of
the deserializer IC, you must write value of 0xA6 to
register address 0x9b at slave address 0x90 to
enable the control channel. In the current revision of
the IC, this step is no longer needed.
10) Start the EV kit software by selecting Start |
Programs | Maxim Integrated | MAXSerDesEV-N |
MAXSerDesEV-N.
11) The Conguration Settings window opens (see
Figure 2) and the GUI automatically searches for
any active listener in both I
2
C and UART mode and
identies a valid GMSL product. Once a valid device
is identied, the corresponding conguration jumpers
are displayed to help users congure the serializer
and deserializer.
12) In case an operating evaluation board with a
Nuvoton microcontroller is not found, a window
appears (Figure 3) warning as such. Press OK to
continue and start the GUI anyway, or press Cancel to
terminate the application. See the Troubleshoot-
ing section at the end of this document and x the
problem before continuing.
13) When an operating Nuvoton microcontroller is found,
the GUI checks the rmware version in the microcon-
troller and prompts the user to update (Figure 4).
14) While the Conguration Settings window is open,
press the Identify Devices button to search for the
devices connected.
15) Only Link Type and Device Address selections on
the Conguration Settings window affects the EV
kit operation. Other items are for user reference only.
16) Press the Connect button to open the
Evaluation Kit window and the devices under test
(DUT) register maps (Figure 5). The GUI will read all
internal registers of the serializer and deserializer and
update the corresponding tabs.

17) Press the Read All MAX96705 button in the Serial-
izer group box to read all the serializer registers.
18) Press the MAX96705 Des tab (Figure 6) and
then press the Read All MAX96706 button in the
Deserializer group box to read all the deserializer
registers.
19) Select any of the other tabs to evaluate other
serializer/deserializer (SerDes) functions.
