BU-63825(925):

DESCRIPTION

The BU-63825/925 BC/RT/MT Sp’ACE-II and BU-63705 Space-RT-II series of MIL-STD-1553 terminals continues Data

Device Corporation’s (DDC’s) commitment to producing hybrids with enhanced processing and screening for space

borne, radiation and Hi-Rel applications. Both terminals are designed specifically to be hardware and software

compatible, direct drop-in replacements for the equivalent Sp’ACE and Space RT series.

The BU-63825/925 Sp’ACE-II is a complete integrated interface between a 1553 bus and a host processor, and

replaces the BU-61582/83 Sp’ACE ( Space Advanced Communication Engine) pin-for-pin with the same 1.9 square

inch package.

The BU-63705 Space RT-II is a terminal for simple, non-CPU based applications, and shares the same 3.78 square inch

package as BU-65142 Space RT, which it replaces.

APPLICATIONS

The new generation of Sp’ACE-II and Space-RT-II terminals are designed for applications requiring the highest levels

of reliability and radiation tolerance*, including such platforms as launch vehicles, satellites and the International

Space Station.

DESIGN

The manufacturing of hybrids for space applications involves enhancements in the area of layout design, processing

and screening. The principle goal of the hybrid mechanical design is to improve the ease of wire bonding and

inspection. All of DDC's space grade terminals utilize ceramic packaging. Ceramic packages eliminate the potential

hermeticity problems associated with the glass beads of KOVAR (metal) packages. In addition, ceramic packages

facilitate improved thermal properties and feature reduced weight and lower cost.
