Overview
3G-SDI technology is the first established standard providing sufficient bandwidth to transmit uncompressed high-
definition video signals from camera to screen.
Using coaxial cables with very low power loss, enables video transmission over 100 meters. This distance can be
increased up to 300 meters using equalization at the receiver.
Twiga 3G-SDI Premium converts the native LVDS video signal from camera blocks to 3G-SDI. It takes advantage of a
high quality, low jitter and uncompressed SDI stream.
The Premium board has an additional analog output which is perfect to conserve your already-in-use analog system.
The dual output 3G and Analog will significantly reduce the number of boards, improving the cost and time-to-market.
The 3G-SDI Premium module is based on a FPGA associated with DDR3 memory. Combined with Twiga’s expertise,
complex image processing functions can be embedded on real time video flow such as colorimetry tests,
measurements, reticules, contrast enhancement, ROI extraction, OSD and even more functions to fit your applications.
The add-on connector on the bottom side offers an infinity of new functionalities. The 3G-SDI Premium can be directly
mounted into your system/end-products (plug-in) or connected to custom designed add-on board. Integrated RTC,
audio embedded to SDI, second video input are some examples of the new possibilities / range of functionalities.
Application example
The 3G-SDI Neo module can be closely fitted to the back of a LVDS camera module to facilitate the system integration.
It enables the customer to harvest the full advantage of this robust solution in their integrated systems in different
kinds of application such as:
o medical cameras
o surveillance
o machine vision
o inspection

SDI video output
The output is an 8-bit SDI signal 800mV pp with 75-ohm impedance. It is compliant to SMPTE 424M (3G-SDI) and
SMPTE 292M (HD-SDI). The output video format is the same as the camera.
Different output connector type are available: BNC, SMB or MCX. Please specify the connector you need in the order.
Analog video output
The analog video output is selectable. You can get Composite video (CVBS), S-video (Y/C) or Component video (YPbPr).
The selection is done via internal registers. The analog video output is available on a 10-pin molex connector.
3 modes can be selected to convert HD 16:9 to SD 4:3:
Selection of the Video mode can be done on by the UART communication (See paragraph communication)

System configuration
Communication
Communication with the camera can be done through J4 with the following pins:
o RX
o TX
o GND
Communication can be set to either RS232 mode (according to EIA RS-232 specification) or TTL mode (UART with 3.3V
compatibility).
Selection between both mode is done by SW1 switch (See paragraph Switches)
The camera communication use VISCA protocol and will follow camera specifications, please check the camera
datasheet to address all available commands.
The board parameters are also accessible from this connector with VISCA protocol at Address 0x82.

Switches: communication and video format
4 DIP switches are available.
Switch 1: to select the communication standard between RS232 and TTL.
Switch 2- 3- 4: to select the video format. The board checks, when the camera power is on, if the camera video format
corresponds to the switches, otherwise it sends a VISCA command to change the format. It can be changed
dynamically; the system will automatically detect the format change and display the video in the format requested.
An "External" mode is available to use the actual format of the camera, it does not change the video format of the
camera.

Troubleshooting
Get hardware and software version
The hardware version is a letter written close to the reference of the board TV10 0090. The software version is written
on a green sticker stuck on the top side of the board. Be careful, the 3G/HD-SDI can be updated by the customer, in
this case the green sticker can be not at the correct version. You can still read internal registers to get the correct
version.
Update via UART
An update of the board is possible by distance, you need an UART connection with the board and a Java application
made by Twiga. You can find the application and the different available software version on www.twiga-support.com
where a changelog file gives you all the information about the features updated in each version.
If you do not have an account on our support website, please register and send us a mail at [e-mail]
specifying which board you are working with. This way we will give the rights to have access to our different
documentations and software.
Common issues
If you have any problem getting the video, here some points you need to check:
o Power supply is correctly connected to the board, no consuming issue or overheating of the board
o No damaged cable, you can check using other 30-way Kel cable, if possible, check the output cable used to
get the video
o The video format of the camera is correct and supported by the board
o Try with another LVDS compatible camera to be sure the issue is not coming from the camera
o You can check on our support website that there is no new software version solving your issue
If you are not able to find the cause of the issue, please contact us at [e-mail] and we will give you
support. Explain us the problem you are facing with as much details as possible and please add the hardware and
software version of your board.
