EBR-1553 is a communication standard based on MIL-STD-1553, but specified to operate at a higher data rate of 10 Mb/s. EBR-1553 operates over a hub (star) topology, with the Bus Controller (BC) node at the center of the hub and RTs located on the spokes. The EBR-1553 physical layer calls for point-to-point connections using RS-485 transceivers.
EBR-1553 is based on MIL-STD-1553’s familiar command/response protocol, thereby enabling deterministic communication and providing error detection. In addition to its 10 Mb/s data rate, the MIL-STD-1553 response time and intermessage gap time values are modified for 10 Mb/s operation. EBR-1553 is deployed on weapon systems, including the Small Diameter Bomb (SDB).
Sital’s EBR-1553 products includes an IP core. This core provides DDC’s Enhanced Mini-ACE register/memory architecture; BC, RT and Monitor operation; and includes a hub that can be instantiated to provide any number of ports up to and including 32. The core can be supplied with software API/library/drivers for Windows, VxWorks and Linux. The API/library/drivers provide the same API that Sital provides for is MIL-STD-1553 IP and standard (single-function) boards and is also compatible with DDC’s AceXtreme API.
Sital also offers EBR-1553 boards in a variety of form factors, including PCI Express, PCI, PMC, VME, PC/104, Compact PCI, and USB. Two versions of boards are available: standard interface boards and tester boards. Both versions of EBR-1553 boards provide BC, RT and Monitor operation and include 4-port EBR-1553 hubs, along with Windows API/library/driver software. In addition, the tester versions of the boards provide error-injection capabilities and also include the COMposer Windows GUI software.
