Matrox Radient eV overview

Matrox Radient eV is a family of two high-performance PCIe frame grabbers:

  • Matrox Radient eV-CL. Matrox Radient eV-CL supports image capture from up to 4 video sources that use the Camera Link (CL) communication standard, depending on the version. There are 4 versions of Matrox Radient eV-CL available: Matrox Radient eV-CL DB, Matrox Radient eV-CL QB, Matrox Radient eV-CL SF, and Matrox Radient eV-CL DF.

  • Matrox Radient eV-CXP. Matrox Radient eV-CXP supports image capture from up to 4 high-resolution, high-speed video sources that use the CoaXPress (CXP) communication standard. There are 3 versions of Matrox Radient eV-CXP: Dual CXP-6, Quad CXP-6, Quad CXP-6 for 3D profiling.

Matrox Radient eV supports frame and line-scan, monochrome and color video sources. The color video sources can be RGB video sources or video sources with a Bayer color filter. Matrox Radient eV can decode Bayer color-encoded images and perform color space conversions while transferring the images to the Host. In addition, it can vertically or horizontally flip them and perform subsampling.

Matrox Radient eV-CL supports up to 4 Base or 2 Full/80-bit mode Camera Link connections, depending on the version of the board, as well as providing Power-over-Camera Link (PoCL) support.

Matrox Radient eV-CXP supports up to 4 independent CoaXPress connections, allowing simultaneous image capture from up to 4 video sources that transmit data at different CoaXPress speeds (up to 6.25 Gbits/sec). Alternatively, using link aggregation, the frame grabber can receive image data at up to 25 Gbits/sec from a single video source. Matrox Radient eV-CXP provides up to 13 W of power per CoaXPress connection to any device that supports power-over-CoaXPress (PoCXP).

3 Matrox Radient eV has 128 Mbytes of acquisition memory mapped onto the PCIe bus. You can use a Host pointer to access this memory, or you can access it directly from another PCIe bus master; this memory is referred to as shared memory.

Note on nomenclature

This manual refers to all versions of the board as Matrox Radient eV. Matrox Radient eV-CL refers to Matrox Radient eV-CL SF, Matrox Radient eV-CL DF, Matrox Radient eV-CL DB, and Matrox Radient eV-CL QB versions. Matrox Radient eV-CXP refers to Dual CXP-6, Quad CXP-6, and Quad CXP-6 for 3D profiling. When necessary, this manual distinguishes between the Matrox products using their full names.
