Camera & Video Interfaces for Aerospace & Defense

A lot of computing systems do only provide video signals in HDMI format. Even if system builders are designing their own baseboards, they usually are limited by the options which are available for commercial of the shelf chip sets.

Nevertheless, larger aerospace vehicles do need a video transmission that supports longer distances than the HDMI standard allows. A good alternative would be transmitting video information with the SDI Standard that is very common in video broadcast and other video markets.

What is the challenge?

To convert an HDMI signal into SDI there are several converter boxes in the market. There are two categories:

1. Consumer Electronics

Consumer electronics which are usually do not support enhanced operating conditions since they are designed to work in a private living room.

2. Professional Studio Equipment

Professional Studio Equipment also sometimes does not support enhanced operating conditions and that is usually large and expensive

Converter Solutions for AVIONICS

To solve this issue for systems builders the AVION NA1012B-EH was built. On a size that is even less than 4cm x 4cm, the HDMI to 3G-SDI Converter is generating an SDI signal out of an HDMI signal with the same resolution and frame rate. This converter is designed to generate SDI signals on a very small form factor board and support operating conditions between -40°C and +85°C. The board comes with a board-to-board connector for power supply and HDMI input and can be mounted with screws on your system board. That also allows usage in systems that have some mechanical vibrations.
