Lx1553-5 MIL-STD-1553 PCI/PCIe Interface

The LP1553-5 (PCI) and LE1553-5 (PCIe) are personal computer expansion cards for communicating with MIL-STD-1553 systems. These feature-rich interfaces provide programmable data buffers and deep built-in memory. MIL-STD-1553 capability includes BC, RT, and/or Monitor. Avionics discretes can be used as general purpose I/O or linked in hardware to 1553 databus activity as triggers or syncs.


The Lx1553-5 model line supports maximum data throughput on all 1553 interfaces. Each channel is independently configurable as Bus Controller, Remote Terminal(s), and/or Bus Monitor. Messages can be captured by a sequential monitor for all channels, or via RT map monitoring. Notification of databus activity is handled through the on-board Event Log, which can be processed by polling or via an interrupt. To dramatically reduce the host CPU processing, the sequential monitor has a DMA mode that automatically moves records to host memory through PCI/PCIe bus mastering.
