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
