Part Number(s): BU-65565
Package: PMC Card
Lead Free Information: B

The BU-65565 1553 PCI Mezzanine (PMC) card offers a comprehensive solution for interfacing between embedded PCI and MIL-STD-1553 buses. The conduction cooled version, built to VITA-20 specifications, features a robust design with thermal vias, a heat spreading plane, and copper strips providing a thermal interface to baseboard rails. The card has passed extensive shock and vibration testing. The BU-65565 MIL-STD-1553 card is also available as a convection-cooled card, with a choice of rear-panel, front-panel, or rear- and front-panel input/output.

The BU-65565 includes one to four channels of DDC's field-proven, industry standard Enhanced Mini-ACE. This advanced 1553 bus controller architecture provides a high degree of flexibility and autonomy: improving message scheduling control; minimizing host overhead for asynchronous message insertion; and facilitating bulk data transfers and double buffering, message retry and bus switching strategies, and data logging and fault reporting. In addition, the 1553 PMC card's remote terminal architecture meets all common MIL-STD-1553 protocols. RT data buffering and interrupt options offer robust support for synchronous and asynchronous messaging while ensuring data sample consistency and supporting bulk data transfers.

Free BU-69090 software with a library supports all modes of operation, VxWorks and Linux device drivers (including source code), and an offline development environment.
