DDC BU-65569T4-200 MIL-STD-1553 CompactPCI Interface Card

The DDC BU-65569T4-200 is a 3U CompactPCI interface card that implements MIL-STD-1553B Notice 2 and MIL-STD-1760 communication protocols for military and aerospace systems. Built on DDC’s Enhanced Mini-ACE® architecture, it delivers four independent MIL-STD-1553 channels, each programmable as Bus Controller (BC), Remote Terminal (RT), Monitor (MT), or combined RT/Monitor. The card provides 64K words of RAM per channel, transformer or direct coupling options, and supports dual-redundant configurations. With 3.3-volt logic and convection cooling, it operates at low power while maintaining real-time data integrity for simulation, test, and embedded mission systems.
