Radiation tolerant SpaceWire router for satellite on-board networking

The European Space Agency (ESA) recently propsed the SpaceWire standard for reliable satellite on-board networking at high speeds. This paper presents the design of configurable SpaceWire router and interface hardware macrocells, the first in state-of-the-art compliant with the latest standard extensions, Protocol Identification and Remote Memory Access Protocol. The SpaceWire router with 8 links achieves 100 Mbits/s data-rate with 1.35 W power consumption and 300 Krad radiation tolerance. These performances meet the requirements of planned ESA space missions
