MAX9406 Evaluation Kit
General Description
The MAX9406 PCIe
®
-To-HDMI™ evaluation kit (EV kit) is
a fully assembled and tested circuit board that demon-
strates the capabilities of the MAX9406 DisplayPort™ to
DVI™/HDMI level shifter. The correct version of the Intel
graphics chipset driver and video BIOS need to be
installed properly to use the MAX9406 EV kit.
The MAX9406 EV kit should be plugged into a PCI
Express
®
(PCIe) bus slot on a PC that supports
DisplayPort as defined by VESA, such as Intel’s
Eaglelake/Cantiga chipset with an integrated graphics
controller.
The MAX9406 EV kit PCB comes with a MAX9406ETJ+
installed (32-pin thin QFN package with an exposed pad).

Quick Start
Recommended Equipment
Before beginning, the following equipment is needed:
• MAX9406 EV kit
• A PC using Intel’s Eaglelake/Cantiga chipset with an
integrated graphics controller
• A built-in laptop LCD screen or an external monitor
with a VGA interface as the primary display
• Another LCD monitor with a DVI or HDMI interface
as the secondary digital display
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
®
operat-
ing system.
Procedure
The MAX9406 EV kit is fully assembled and configured
for HDMI output on J2. Follow the steps below to verify
board operation:
1) Verify that all jumpers (J3–J11) are in their default
positions, as shown in Table 1.

2
2) Check if the graphics driver and video BIOS are
already installed by moving the mouse pointer
(arrow) all the way down to the bottom of the primary
display to show the task bar. Look at the notification
area (system tray) at the right side of the task bar to
find the
Digital Display
utility. If not found, the
graphics driver and video BIOS need to be installed.
3) Carefully plug in the MAX9406 EV kit into an avail-
able PCIe bus slot. Connect an LCD monitor with an
HDMI interface to the HDMI plug on the MAX9406
EV kit using an HDMI cable. Or, connect an LCD
monitor with a DVI interface using a DVI-to-HDMI
conversion cable.
4) The secondary monitor connected through the HDMI
port will light up if the digital display is enabled. If no
video appears, move the mouse pointer (arrow) all
the way down to the bottom of the primary display to
show the task bar. Further, move the mouse pointer
to the notification area at the right side of the task
bar and onto the
Digital Display
utility. Right click
the
Display Port
and then select the
Digital Display
and Monitor
option. The LCD monitor connected to
the EV kit will light up.

MAX9406 Evaluation Kit
Detailed Description of Hardware
The MAX9406 (U1) level shifts all four high-speed dif-
ferential data channels and the DDC channel. High-
speed channel data comes from the PCIe bus (J1),
goes through the MAX9406, and outputs at the HDMI
connector (J2). The MAX9406 is enabled by jumper J8.
The MAX9406 also relays the hot-plug detection signal
from the HDMI plug to the PCIe bus through an inverter
(U5-D) when a shunt is placed across pins 2-3 of
jumper J9. The hot-plug detection signal is amplitude-
limited to 0.9V at the PCIe bus side.
The 5V supply matching the HDMI interface side is con-
verted down from the 12V supply of the PCIe bus by
the MAX1659 (U2). Three MAX3208E chips (U4, U6,
and U7) provide ESD protection for both high-speed
and DDC channels on the HDMI interface. The
AT24C02 EEPROM (U3) provides an EDID for testing
purposes. The AT24C02 is initially un-programmed.
Pullup resistors (1.5kΩ) are provided on both PCIe and
HDMI sides of the DDC channel.

Evaluating the MAX9406
DP-to-HDMI Dongle Board
The MAX9406 EV kit can also be used to evaluate a
MAX9406-based DP-to-HDMI level-shifter dongle
board. To evaluate a dongle board, move resistors
R28–R35 to locations R20–R27 to isolate the MAX9406
on the EV kit.
Note:
Connector U8 is mounted at
assembly, but is not production tested.
