Frame grabbers ride PCI Express
By Staff -- Test & Measurement World, 12/1/2006 2:00:00 AM
Dalsa’s X64 Xcelera line of scalable frame grabbers for the PCI Express bus currently support Camera Link cameras, and the company reports that future versions will support multiple input progressive-scan analog and parallel low-voltage differential signaling (LVDS) digital cameras.
The initial Xcelera models include the X64 Xcelera-CL PX4 Dual and the X64 Xcelera-CL PX4 Full versions. Both half-length x4 PCI Express boards support 85-MHz operation and are compatible with 64-bit versions of Windows XP Professional.
The Dual version complies with Dalsa’s Trigger-to-Image Reliability (T2IR) framework to enhance acquisition control throughout the image-capture sequence, and it can acquire images from one Medium Camera Link camera or simultaneously from two Base cameras. The Dual version also performs FPGA-based processing (including Bayer decoding and shading correction for each input) and provides onboard optically isolated quadrature-shaft-encoder input.
The Full version can acquire images from one Base, Medium, or Full Camera Link camera. It can acquire images at rates to 1 Gbyte/s and transfer them to host memory at the same rate. The Full version of the frame grabber also supports an extended feature set for non-Camera Link configurations.
Base price: $1000. Dalsa, www.dalsa.com.
