Matrox Rapixo CXP acquisition
Matrox Rapixo CXP can capture video from digital video sources compliant with
the CoaXPress standard 2.0 specification (as well as 1.1 and 1.1.1). Matrox Rapixo
CXP has four independent acquisition paths (CoaXPress connections). When a
video source is connected to Matrox Rapixo CXP, the board communicates with
the video source to determine the rate at which data will be transferred. Matrox
Rapixo CXP can provide power-over-CoaXPress to attached video sources.
For each video source connected to the board, Matrox Rapixo CXP supports a
CoaXPress trigger output signal, which is used to communicate exclusively with
the video source. To communicate with other third-party devices, Matrox Rapixo
CXP provides 32 auxiliary signals. Auxiliary input signals can be rerouted to the
CoaXPress trigger output signal and the CoaXPress trigger input signal can be
rerouted to auxiliary output signals.
Matrox Rapixo CXP supports monochrome, RGB color, and Bayer color-encoded
acquisition. The board can perform color-conversion, flipping, and image
subsampling.
Performance
The maximum data transmission rate that you can achieve depends on the length
of your coaxial cable, the quality of the cable, your video source, as well as the type
of PCIe slot in which you install your Matrox Rapixo CXP.
Effect of cable length
For lengths greater than 40 m, the longer the cables, the lower the maximum
possible bit rate. High-quality cables, such as Belden 1694A cables or
Belden 4794R cables, will allow for the highest possible bit rates. The table below
