The most efficient multi-channel solution for NTDS applications available today
The NTDS VME PAK brings the power and performance of IXI Technology’s state-ofthe- art PCI Mezzanine Card (PMC) technology to VMEbus systems. The NTDS VME PAK allows two independent MIL-STD-1397C NTDS channels to reside in the space of a single 6U VME slot. It can be configured with any combination of parallel or serial NTDS types A, B, C, D, E or H. With the ability to address up to 16 NTDS ABCH VMEs on the same VMEbus, as many as 32 NTDS I/O channels can be addressed while occupying half the space required for single board NTDS channels. Whether designing a new system or looking for ways to upgrade an existing system, NTDS VME PAK is the right solution for reducing space requirements while maintaining or increasing the number of NTDS channels, especially where numerous channels are needed.
The NTDS VME PAK is easy to program and offers a variety of input and output modes to support any NTDS protocol. The included software device driver and application programming interface (API) library ensure smooth integration of your application with the NTDS ABCH VME’s PMC channels in VMEbus address space. Hardware-independent input and output channels allow the NTDS VME PAK to perform simultaneous input and output (full duplex) operations. On parallel channels, the NTDS type is software-selectable allowing quick reconfiguration without the use of hardware jumpers or switch settings.
The NTDS VME PAK 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.
For maintenance and reliability, NTDS VME PAK parallel channels use short-circuit protected outputs to prevent failures due to improper cabling or NTDS type mismatch. An internal loopback path allows the NTDS VME PAK to be tested without disconnecting cables. The NTDS VME PAK 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 NTDS VME PAK to be deployed and supported for years to come.
