V1145 12-Port 1394b AS5643 XMC Card

The V1145 provides a complete 1394b AS5643 interface solution.  The solution utilizes only one FPGA chip, unlike three or four chip predecessors, allowing for higher port density, with a reduction in size, weight, and power of the interface. This on-board FPGA provides bus control, diagnostics information, interface choices, and customization options not previously available. The V1145 offers twelve 38999 wired transformer-coupled 1394b ports. The host interface provided is available as Gen2 PCIe or 64-bit PCI. The twelve 38999 wired ports are perfect for rugged boxes or chassis where 38999 connectors directly to the PMC/XMC card are desired.
