DDC BU65549M2 MIL-STD-1553 BC/RT/MT PCI Interface Card

The DDC BU65549M2 is a PCI interface card that bridges standard PCI buses to one or two independent, dual-redundant MIL-STD-1553B data buses. It operates as a Bus Controller (BC), Remote Terminal (RT), or Monitor Terminal (MT) with full MIL-STD-1553A and B compliance, STANAG 3838 certification, and support for McAir protocols A3818, A5232, and A5690. Each channel integrates DDC’s Mini-ACE Plus hybrid with dual transceivers and complete protocol encoding/decoding for real-time simulation, testing, and system integration tasks. ## Technical Specifications • **Interface:** PCI Bus
• **MIL-STD-1553 Compliance:** MIL-STD-1553A and B Notice 2, STANAG 3838
• **Channels:** Single or dual channel configuration
• **Operating Modes:** Bus Controller (BC), Remote Terminal (RT), Monitor Terminal (MT)
• **Shared RAM:** 64K words per channel (256K bytes total for dual-channel configuration)
• **Time Tag Resolution:** 16-bit counter with programmable resolution (2, 4, 8, 16, 32, or 64 µs per LSB)
• **BC Frame Timing:** 100 µs/LSB resolution (Frame Time Remaining), 1 µs/LSB resolution (Message Time Remaining)
• **Built-In-Test:** Wrap-around BIT
• **Interrupt Control:** Register programmable level with flexible generation modes; supports interrupt and polling operation ## Key Features • Dual transceivers per channel for redundant bus operation
• RT mode memory management with circular buffer options (128 to 8192 words) and broadcast/non-broadcast data separation
• BC mode stack for multi-message frame scheduling with real-time chronology logging
• Software-programmable RT address selection and command illegalization
• Monitor modes: word monitor, selective message monitor, combined RT/selective message monitor, with simultaneous RT/Monitor capability
• Monitor command filtering ## Typical Applications • MIL-STD-1553B network testing and validation
• Real-time avionics system simulation
• Multi-terminal system integration
• Redundant bus monitoring and diagnostics ## Compatibility & Integration Includes free “C” software subroutine library. Operates on standard PCI bus platforms supporting MIL-STD-1553A/B protocols and STANAG 3838 requirements.
