1 SDI Plugin Module (1x slot)
The photonSDI system consists of:
1) a development test system with two off-the-shelf circuit boards: an evaluation board and an SDI interface board to handle electrical conversion. 2) A prototype implementation of a custom caseboard that plugs directly into the Axiom Camera and adds SDI connectivity.
1.1 How it works
A description of a desired SDI connectivity is created using the LiteX framework (a fork of Migen).
The framework generates a Hardare Description Language (HDL) reprensentation in Verilog.
The HDL is passed to the tool chain, which generates a configuration for the chip on the evaluation SDI Extension Board.
The configuration is loaded onto the chip on a base board that is plugged into the camera.
Camera with chip has new functionality for connecting to professional SDI video equipment.
1.2 Technical Details
Implemented in:
Hardware description language loaded into chips
litex,a Python framework for building custom hardware
Based on liteX
Supported hardware platforms:
Field programmable gate array (FPGA) evaluation board AC701 + SDI interface evaluation board TB-FMCH-12GSDI
Camera Apertus AXIOM beta + SDI extension board
Source code is available on GitHub [1]
1.3 Notes
The initial development is sponsored by the German federal ministry of education and research (BMBF) via the Prototype Fund.
An industry standard serial digital interface (SDI) connection plugin module will provide a nominal data transfer rate of 3G/6G.
