The MIL-STD-1553B RT Coupler is an integrated and cost effective 1553 Remote Terminal Coupler sub- system, implemented in space qualified hybrid technology.
The MIL-STD-1553B RT Coupler performs both electrical and protocol coupling between a single 1553B bus interface and a user interface.
This 1553 Remote Coupler equips all Ariane 5 launchers
The MIL-STD-1553B RT Coupler consists of one Single Transceiver and one Remote Terminal ASIC, manufactured in hybrid technology and available in a standard flat-pack package in order to be easily integrated and to reduce the board size.
Sub-system easy integration is achieved thanks to the open user interfaces and optimized architecture.The RT Coupler functionalities can be easily extended by direct connection to registers, CAN or memory components, without additional processing unit.
Dedicated services are also provided in order to download the user application from protocol management tasks: words validity is automatically checked and only valid messages are transmitted to the application.
Especially relevant for space applications, the MIL-STD-1553B RT Coupler has a low power consumption and a radiation tolerance better than 100 kRads (functional).
The MIL-STD-1553B RT Coupler is already space qualified on several programs like ARIANE-5, GOMOS, ASAR, MHS, STENTOR, E 3000, COLOMBUS and International Space Station.
