MIL-STD-1553 DESIGNER’S GUIDE PREFACE Since its inception in 1973 and in subsequent revisions during the ensuing years, MIL-STD-1553 has evolved into the predominant, internationally accepted networking standard for the integration of military platforms. Supporting documents such as the MIL-STD-1553 Multiplex Applications Handbook, the RT Validation and Production Test Plans, and DDC’s MIL-STD-1553 Designer’s Guide, have positively influenced the standard’s worldwide familiarity and acceptance. Today, 1553 has expanded beyond its tra- ditional domain of US Air Force and Navy aircraft to encompass applications for combat tanks, ships, satel- lites, missiles and the International Space Station Program. Despite the recent advent of newer and higher-speed technologies, it is clearly evident that 1553 will continue to be used extensively in evolving upgrade programs as well as for new applications and integration platforms for years to come. Focused on meeting the needs of hardware and software design engineers confronted with 1553/1760/1773 interface and/or test requirements, DDC is pleased to publish and provide you with this sixth edition of the Designer’s Guide for the MIL-STD-1553 community. As in its five previous editions, the Designer’s Guide is divided into sections to facilitate your ease of ref- erence and review. Section I provides you with an overview of the philosophy and implementation of MIL- STD-1553B and several related standards. Using DDC 1553 products to illustrate key points of interest within the framework of these technical discussions, Section I also presents a comparison of MIL-STDs- 1553A and B as well as an overview of MIL-STD-1760B. Taken directly from the MIL-STD-1553 Multiplex Applications Handbook, Section II provides you with a complete copy of MIL-STD-1553 for your refer- ence, and, a section-by-section interpretation of the rationale behind the various paragraphs in the stan- dard. Plus, for your ongoing reference requirements, copies of Notices 1 and 2 to MIL-STD-1553B, as well as the Production Test Plan and Validation Test Plan are presented in Sections III through VI. As the leading full-range developer and manufacturer of 1553 data bus components, boards and software, DDC offers a comprehensive collection of technical data sheets delineating our wide array of 1553 data conversion and communications products in Section VII. These include fully integrated BC/RT/MT compo- nents, transceivers, RT components, transformers, software and a host PCMCIA, VME/VXI and PC-com- patible communications and tester/simulator board products. The most recent information regarding DDC’s 1553 product uses, including space-level applications and our series of Advance Communication Engine (ACE) terminals, is presented in Section VIII. A series of application notes, highlighting practical uses and design concerns when implementing 1553 technology, is provided in Section IX. A listing of corresponding DDC and DESC part numbers is provided in Section X. For your reference, Subject and Product Number Indices are provided in Section XI. DDC would like to thank Chris deLong and Crossgrove & Associates, for their contributions to the Designer’s Guide’s development, and the U.S. Air Force for allowing us to present portions of their MIL-STD-1553 Multiplex Applications Handbook. We would also like to extend our gratitude to our cus- tomers and friends who have attended our seminars and shared their 1553 experiences with us. We sincerely hope this sixth edition of DDC’s MIL-STD-1553 Designer’s Guidewill prove useful as a working document and reference source, enabling you to resolve your requirements in a practical, efficient, cost-effective, reliable manner. While we have made every effort to ensure the accuracy and correctness of the information presented within these pages, we ask that you do not hesitate to call our attention to any omissions, oversights, errors, miscalculations or any suggestions you might have for enhancing and improving this publication. Thank you for your attention, ongoing consideration and patronage. ILC Data Device Corporation iii
