Frame Grabbers Blow Off Speed Limits

Matrox Imaging introduces its Rapixo CXP series multi-link CoaXPress 2.0 frame grabbers that support data rates up to four times 12.5 Gb/s, with a PCIe x8 host computer interface to match, as required in high-speed, high-resolution machine vision applications. The boards feature up to four connections and support for Power-over-CoaXPress (PoCXP) that combines power, command, and data interfaces onto one cable. They also offer custom onboard image processing using a field-programmable gate array (FPGA) and can also host the license for Matrox Imaging software, avoiding the need for a separate hardware key.

New VNA technologies enable mmWave broadband testing to 220 GHz, helping researchers and engineers to overcome test challenges and simplify mmWave testing.

Application development in the mmWave frequencies is growing. Broadband testing over hundreds of GHz of bandwidth is subject to repeatability/accuracy deficits, and engineers demand solutions to help overcome challenges and simplify mmWave testing.
  • Rapixo CXP supports up to four connections to either interface with up to four CXP 2.0-compliant cameras or to accommodate higher data rates from one or two cameras through connection aggregation. The PoCXP design streamlines system set up by combining the camera’s power interface with its command- and data-interface onto the same coaxial cable.
  • Rapixo CXP makes use of a FPGA device from the Xilinx Kintex UltraScale family for not only integrating the control, formatting, and streaming logic of the various interfaces, but also allowing developers to incorporate Matrox Imaging- or user-developed custom image pre-processing operations—developed in C/C++—to offload from the host computer.
  • Applications using the Rapixo CXP are programmed using the latest MIL software development kit (SDK) and can target either 64-bit Windows or Linux. The frame grabber series also facilitates application deployment through an integrated license fingerprint for MIL software. 

Since a picture is worth at least a buck fifty and this is about frame grabbers, watch a video and learn the significance of CoaXPress 2.0 and Matrox Rapixo CXP, which includes a Q&A with the company. While you’re at, you may as well peruse the Rapixo CXP datasheet.
