Sital Announces the Release of the OCTAVA MIL-STD-1553 Component

Sital Technology, the leader in Mil-Std-1553 IP cores and products, announced today the release of OCTAVA™, a Mil-Std-1553 communication engine, compatible with DDC® Enhanced MiniACE® devices.

The OCTAVA™ family integrates the BRM1553D Mil-Std-1553 protocol engine, a dual 5-volt transceiver, memory management, processor interface logic and 4K or 64K words of RAM in a 72 pin Plastic Quad Flat Pack (PQFP) package. The family consists of bi-directional data buffers and internal address latches to provide a host processor bus with direct interface. The memory management scheme for RT mode provides three data structures for buffering incoming and outgoing data. Combined with the extensive interrupt capability, these structures serve to guarantee data consistency whilst off-loading the host processor.

The OCTAVA devices can also boot-up as RT with the busy bit set for 1760 applications. The BC mode implements several features aimed at providing an efficient real time software interface to the host processor including flexible interrupt generation, automatic frame repetition, programmable inter-message gap times or message rate, and automatic retries.

The OCTAVA™ devices are pin-to-pin compatible with the DDC® BU-65178 and BU-61688 and as such serve as a perfect drop-in electrical, physical and software replacement. An avionics board designed with the DDC® BU-65178 and BU-61688 can work seamlessly with the OCT-65178 and OCT-61688 without hardware or software changes.

“The OCTAVA™ family completely changes the Mil-Std-1553 market. A market that was previously dominated by a single vendor will now benefit from the power of competition”, said Duli Yariv, VP of marketing for Sital Technology. “OCTAVA™ does not only offer price benefits over the competition, but it also introduces many technology and functional advantages for customers” he added.

OCTAVA™ was introduced in partnership with National Hybrid Inc. (NHi), who designed the transceiver and manufactures the device in the USA.
