Digiteq Automotive MGB4 is a modular frame grabber PCIe card for automotive video interfaces. As for now, two modules - FPD-Link and GMSL - are available and supported by the driver. The card has two inputs and two outputs (FPD-Link only). In addition to the video interfaces it also provides a trigger signal interface and a MTD interface for FPGA firmware upload.
