Effect of the type of
PCIe slot

A PCIe 2.x slot supports a higher data transmission rate than a 1.x slot. A by-four
(x4) PCIe slot will lower the data rate by half, when compared to a by-eight (x8)
PCIe slot of the same base specification (1.x or 2.x). While transferring data to
the Host, these factors will reduce the maximum transmission rate as shown in
the table.

Power-over-CoaXPress

Matrox Radient eV-CXP supports power-over-CoaXPress (PoCXP) compliant
video sources, and non-PoCXP compliant video sources. When Matrox
Radient eV-CXP is connected to a proper auxiliary 12 V power supply, the
CoaXPress standard is configured to provide up to 13 W per link, at a nominal
voltage of 24 V, to the connected device.

Matrox Radient eV-CXP detects whether the video source is PoCXP-compliant.
When connecting to non-PoCXP compliant video sources, Matrox
Radient eV-CXP has appropriate circuitry to ensure that no power is transmitted.
To manually disable the PoCXP circuitry and ensure that no power is sent to the
device, you can use the MIL-Lite function

MdigControl()

.

Matrox Radient eV-CXP is also equipped with an overcurrent protection
mechanism and a resettable fuse that can sustain a current of 1 A.

Acquisition

Matrox Radient eV-CXP accepts 8-, 10-, 12-, 14- and 16-bit video data. All data
is transmitted in packets over the CoaXPress links.

The Matrox Radient eV-CXP CoaXPress interface is responsible for buffering
incoming data before it is written to memory, as well as assembling and
disassembling packets from the video sources. Video sources can be frame or
line-scan video sources.
