OmniBus 1553 PMC
OmniBus 1553 PMC has the power and flexibility to operate as a simple or intelligent 1553 interface card or as an embedded processor. Its on-board PowerPC processor and ability to run user
programs make the OmniBus 1553 PMC unique among PMC cards. It is available with either convection cooled front panel or conduction cooled rear panel I/O. Though not modular like other
OmniBus products, it has all OmniBus 1553 features in one or two 1553 channels and a variety of configurations.
OmniBus 1553 Family
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.
High-Performance Architecture
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™).
