ALTA DATA TECHNOLOGIES SELECTS HOLT MIL-STD-1553 INTEGRATED TRANSCEIVER/TRANSFORMER FOR MEZ-E1553 PRODUCT

Alta Data Technologies (Alta) announced it has selected Holt Integrated Circuits MIL-STD-1553 transceiver/transformer integrated product combination, HI-2579, for use in their MEZ-E1553 device, a real-time Ethernet MIL-STD-1553 converter.

The HI-2579 is a 3.3V MIL-STD-1553/1760 dual transceiver with integrated dual transformers. The IC is hermetically sealed on a ceramic LCC substrate and dual transformers are mounted in the same package. The ceramic substrate allows extended temperature operation from −55oC to +125oC and achieves Moisture Sensitivity Level (MSL) 1.

The device operates from a single 3.3V supply and provides a single-component solution to interface an FPGA directly with a dual redundant MIL-STD-1553 bus. The HI-2579 transceiver is available in industrial −40oC to +85oC and extended −55oC to +125oC temperature ranges, with optional burn-in available for extended temperature range devices.

“Holt is very happy Alta once again chose us for their latest product design,” said Anthony Murray, Director of Marketing Communications at Holt. “This product provides them with a robust, compact product ideal for this application.”

“We have worked well with Holt for many years and have many of their parts designed in our products.  The HI-2579 combined transceiver and transformer was a perfect fit for our new MEZ-E1553™ real-time Ethernet MIL-STD-1553 mezzanine board,” said Jake Haddock, CTO of Alta.  “The combination of the transceiver and transformer to a single component allowed us to shrink-down this design to the lowest possible footprint for our customers.”

The MEZ-E1553 is a unique mezzanine card that allows Alta’s customers to design in 1-2 dual redundant 1553 channels in their own embedded design (I/O sub-assembly, SBC, etc.) with a 100/1000 Ethernet host interface.  For many embedded designs, routing Ethernet signals is much easier than a memory, PCI, or PCIe busses. The customer can easily design in Alta’s proven AltaCore™ full-featured 1553 protocol engine, including A/D O-Scope signal debugging, for deployed or test applications.   Full reference schematics and 3-D STEP files are included.

The MEZ, like Alta’s ENET™ products (1000s deployed on 100s of US DoD systems), implements a real-time, hardware UDP server design that eliminates traditional IP/UDP software stacks – virtually eliminating virus concerns.  The product includes a full Berkley Socket Distribution (BSD) AltaAPI™ SDK with source, and 100s of example and ESS test programs – quick and easy integration that can run on almost any operating system, even DO178 systems.

Also available is a low-cost reference design card with a USB Windows/Linux interface that runs the same AltaAPI.  The customer can use the same application software from the reference card directly to the deployed design (allowing engineering teams to work in parallel).  From integration to test, the MEZ-E1553 saves development time while providing a full-featured 1553 interface usually only found on PCIe-type cards.
