Active Silicon AS-PHX-D24CL-PE1 Camera Link Frame Grabber

The Active Silicon AS-PHX-D24CL-PE1 is a PCI Express Camera Link frame grabber for high-speed image acquisition in industrial and scientific imaging systems. Built on PCIe 1.1 x1 architecture with burst rates exceeding 190 Mbytes/sec, this board delivers direct hardware control of image data streaming with zero CPU overhead via scatter-gather DMA and Posted Writes. The board conforms to Camera Link v1.2 specification and accommodates Base Camera Link formats including 8 to 16-bit single-tap, 8-bit RGB, and dual-tap 12-bit camera sources at pixel clock rates up to 85 MHz.
