OmniBus

• Processor: IBM PowerPC® (405GPr), 333 MHz
• Memory: 16MB SDRAM, 4MB Flash
• DIO: 2 inputs, 2 outputs (additional 3 inputs and 3 outputs per core)
• Operating Temperature: 0 to 55°C (extended temperatures available)

OmniBus PCI and cPCI cards provide interfaces for avionics databuses, as well as general purpose digital I/O and IRIG sourcing and synchronizing. The cards can be ordered with one or two modules to support a variety of avionics databus protocols.

• PCI or cPCI form factor
• High channel counts
• Mixed protocols
• IRIG time synchronization
• Extended temperatures available
• Can be upgraded/reconfigured
  

• MIL-STD-1553
• ARINC 429
• ARINC 708
• ARINC 717
• CSDB
• Serial (RS-422/232/423)
• Discrete I/O
  

OmniBus is a highly-flexible and high-performance family of avionics databus interfaces combining a selection of industry-standard platforms (PCI/cPCI, VME, PMC and Ethernet/USB) with a wide-viariety of I/O choices (MIL-STD-1553, ARINC 429, ARINC 708, ARINC 717, Serial, CSDB and Discrete). This sophisticated OmniBus design allows users to order the exact number, functionality, and mix of protocol channels that they need. It also lets users upgrade or reconfigure their OmniBus (at the factory) as requirements change.

OmniBus products are built using an integrated board, core, and module architecture. PCI, cPCI, and Ethernet/USB boards include 1 or 2 cores, VME boards have up to 4, and PMC boards include a single fixed core. Each on-board core has a dedicated protocol processor, IRIG timer, and 3 sync and 3 trigger lines. These cores are the support circuitry for the I/O modules, which contain the interface to the databus protocol(s). Isolating the protocol interface on the I/O module provides the flexibility to create custom, user-specified configurations for single or mixed protocols. The protocol-specific OmniBus architecture provides a better solution with greater performance than general-purpose modular systems (such as IndustryPack™).
