Karbon CL4-D

Karbon-CL is the world’s first four-camera PCI Express frame grabber. It can simultaneously acquire from up to four Base CL cameras or two Full CL cameras. It is built on top of BitFlow’s FlowThru technology which provides zero latency access to data, super low CPU usage, and unlimited DMA destination size. The Karbon-CL is the first member of BitFlow’s Karbon family, a platform that will host a wide variety of virtual frame grabbers. These virtual frame grabbers can be customized to meet your specific needs.

The Karbon-CL has been designed with two main applications in mind. First, in situations where more than one camera is needed, the Karbon-CL can reduce both the system cost and the hardware footprint by its ability to acquire from up to four cameras. Second, in situations where extremely high data rates and/or frame rates are required, the Karbon-CL has been designed to acquire up to 128 bits at 85 MHz pixel clock rate and DMA at data rates up to 2.0 GB/S.

The Karbon CL4-D supports up to four independent base CL cameras.
