Swift™ PCIe NTDS Serial D/E

High performance serial NTDS for PCI

NTDS for a new generation of PCIe bus servers and workstations

The PCIe NTDS Serial card connects computers with PCI Express (PCIe) slots to military computers and peripherals with MIL-STD-1397C Type D or E interfaces. The PCIe is compatible with x1, x2, x4, x8 or x16 PCIe slots, allowing it to be used in the widest range of servers and workstations. NTDS cable connections are backward compatible with IXI’s Serial PCI board, allowing an easy upgrade to the PCIe version without the need to change cabling. It can be configured to fit in standard or low profile enclosures by changing the faceplate. IXI’s PCIe NTDS is easy to program and offers a variety of input and output modes to support any NTDS protocol. Hardware-independent input and output channels allow the NTDS Interface to perform simultaneous input and output (full duplex) operations. PCIe NTDS boards can be used for passive tap applications as well as normal NTDS I/O. An on-board time stamp generator tags individual input words with 125 ns resolution. Time stamping is software-selectable and can be used with active or passive communications. All boards in the NTDS Interface family are software compatible making it easy to mix parallel and serial NTDS boards in the same system as well as allowing transparent migration of applications between PCIe, PCI, PMC, cPCI, and PC/104-Plus versions of the PCIe NTDS. Device driver software is available for the most commonly-used operating systems. For maintenance and reliability, an internal loop-back path allows the NTDS Interface to be tested without disconnecting cables. PCIe NTDS Serial Type E boards fully implement all the System Integrity Features (SIF) specified in MIL-STD- 1397C. The PCIe NTDS can be updated in the field by reconfiguring its Field Programmable Gate Array (FPGA) logic to add features or compensate for non-compliant interfaces. Using FPGA technology reduces component obsolescence, enabling the PCIe NTDS to be deployed and supported for years to come.
