Total-OCTAVA™️ MIL-STD-1553 Terminal with DDC®️ Compatibility
MIL-STD-1553 Terminal with Integrated Transformers
Providing Compatibility with DDC® Total-ACE®
Total-OCTAVA™ — A Complete, Future-Proof MIL-STD-1553 Solution
Sital’s Total-OCTAVA™ delivers a fully integrated, all-digital MIL-STD-1553 solution designed for long-life aerospace and defense platforms, combining proven field experience with modern FPGA technology.
The Total-OCTAVA™ is a pin-to-pin replacement for DDC’s® BU-64863 Total-ACE®, providing full electrical, mechanical and architectural compatibility.
Fully Integrated Architecture
Sital’s Total-OCTAVA™ MIL-STD-1553 devices integrate a complete solution in a compact 312-ball Plastic BGA (Ball Grid Array) package.
That package integrates:
-
BC/RT/Monitor or RT-only MIL-STD-1553 protocol engine
-
Memory management and processor interface logic (4K or 64K words of RAM)
-
Dual 1553 transceiver and dual transformer
Ultra-Low Power Design
Sital’s MIL-STD-1553 transceivers are designed for extremely low power consumption and heat dissipation, supporting power-sensitive avionics and mission-critical platforms.
Cyber Security at the Data-Bus Level
Total-OCTAVA™ BC includes Sital’s unique Embedded BC FireWall capability.
The BC can detect messages transmitted by an impersonating Bus Controller and report them to the host processor. An optional Intrusion Protection System (IPS) provides additional protection against malicious or unintended bus activity.
Proven Heritage
The design of Total-OCTAVA™ is based on Sital’s original OCTAVA™, a drop-in replacement for DDC’s® Enhanced Mini-ACE.
Over the past decade, thousands of OCTAVA devices have been deployed and flown in operational military systems, establishing a strong field-proven foundation for Total-OCTAVA™.
Built on Lattice Certus™-NX FPGA Technology
Total-OCTAVA™ is implemented on Lattice Semiconductor’s Certus™-NX FPGA, leveraging its low power consumption, high reliability, and long-term availability — key requirements for aerospace and defense programs with extended lifecycles.
This architecture enables a future-proof, all-digital MIL-STD-1553 solution, while maintaining full form-fit-function compatibility with legacy DDC® Total-ACE® devices.
