ADA-LVDS-DVI / Introduction
3
2Introduction
The ADA-LVDS-DVI is a converter module from LVDS (Low Voltage Differential Signaling) to DVI (Digital Visual
Interface). It offers a DVI-D interface with single-link TMDS® and DDC (Display Data Channel) compliance. This
converter module can support DVI monitors with resolutions up to UXGA (1600x1200).
This converter module is designed for the use with Kontron Embedded Modules GmbH embedded computer boards
that support the JILI (JUMPtec Intelligent LVDS Interface) standard. For the support of the complete functionality of
DVI (including the DDC support) it is necessary that a VideoBIOS with DDC auto-detection capability is installed on the
embedded computer board. Currently this is supported on modules with Intel® chipsets (852/855 and newer). Please
contact your technical support for information about available BIOS versions to support this feature.
Most LVDS interfaces are 18 and 24bit compatible to work with default ADA-LVDS-DVI 24bit. For chipsets supporting
18bit LVDS only the second variant ADA-LVDS-DVI 18bit should be used.

3.6 MTBF
The following MTBF (Mean Time Between Failure) values were calculated using a combination of manufacturer’s test
data, if the data was available, and a Bellcore calculation for the remaining parts. The Bellcore calculation used is
“Method 1 Case 1”. In that particular method the components are assumed to be operating at a 50 % stress level in a
40° C ambient environment and the system is assumed to have not been burned in. Manufacturer’s data has been
used wherever possible. The manufacturer’s data, when used, is specified at 50° C, so in that sense the following
results are slightly conservative. The MTBF values shown below are for a 40° C in an office or telecommunications
environment. Higher temperatures and other environmental stresses (extreme altitude, vibration, salt water
exposure, etc.) lower MTBF values.
»Module MTBF (hours) : > 125.000

ADA-LVDS-DVI / Getting started

5Getting started
Getting started with the ADA-LVDS-DVI adapter is very easy. For location of the connectors, see Chapter 3: Connector
Layout. Take the following steps:
»Turn off the power supply of your system.
»Connect the 40pin flat-foil cable coming with the adapter to the ADA-LVDS-DVI printed circuit board.
»Connect the other side of the flat-foil cable to the JILI connector of your Kontron module or to the
corresponding base board equipped with a JILI connector.
»Connect the DVI monitor to the DVI interface connector of the ADA-LVDS-DVI printed circuit board.
»Make sure all your connections have been made correctly.
»Turn on the power of your DVI monitor and of your system.
»Enter the BIOS of your Kontron Embedded Modules GmbH board and make sure the JILI interface (LVDS) is
activated. See the BIOS chapter of the manual for the corresponding board you are using for details.
Note: Only use the 40pin flat-foil cable delivered with the ADA-LVDS-DVI adapter for connection to the JILI
connector. This flat-foil cable has its contacts of both cable ends on the same side. A flat-foil cable delivered
with another JILI-adapter usually has its contacts on both cable ends on different sides and may damage
your system.

ADA-LVDS-DVI / LVDS Interface
12
7LVDS Interface
The LVDS interface functions as an input to the ADA-LVDS-DVI module. It is available through the flat-foil connector
J2 (40 pins). You can connect the LVDS interface to your Kontron Embedded Modules board's JILI connector via the
40pin flat-foil cable delivered with this adapter.
Note: Only use the 40pin flat-foil cable delivered with the ADA-LVDS-DVI adapter for connection to the JILI
connector. This flat-foil cable has its contacts of both cable ends on the same side. A flat-foil cable delivered
with another JILI-adapter usually has its contacts on both cable ends on different sides and may damage
your system.

8.2 DDC and Hot-Plug information
The ADA-LVDS-DVI is equipped with an onboard microcontroller. After power-on of the system the /HOTPLUG signal of
the LVDS interface goes high for about 10ms and the microcontroller is initialized. After initialization the /HOTPLUG
signal goes low and the microcontroller will read in the DDC (Display Data Channel) of the connected DVI monitor.
This transaction runs with 10kHz by using the signals DDCDAT and DDCCLK and is completed within 500ms. Then
/HOTPLUG goes high again. After this transaction is finished the Kontron Embedded Modules GmbH embedded
computer board reads the DDC structure from the microcontroller through the DDC signals of the JILI interface
(DDC_DAT and DDC_CLK) with up to 100kHz.
In case of the system is already powered up and the DVI Monitor is connected later (Hot Plug), the signal HTPGL on
the DVI interface goes high and the microcontroller starts reading the DDC from the DVI Monitor. After all of the DDC
data is read the /HOTPLUG signal on the LVDS interface goes high and the embedded computer board reads the DDC
structure from the microcontroller.
Note: The DDC and Hot Plug feature requires BIOS support. Currently it is only possible to use it on boards
equipped with the Intel® chipsets (852/855 or newer). Please contact your technical support for
information about the required BIOS version for your special Kontron Embedded Modules GmbH board.
