ERVAC SpaceWire - Technical data paceWire technology has grown organically from the needs of on‐board processing applica- tions. One of the principal aims of SpaceWire is the support of equipment compatibility and reuse at both the component and subsystem levels. Integration and test of complex on‐board systems is also supported by SpaceWire with ground support equipment plugging directly into the on‐board data‐handling system. Monitoring and testing can be carried out with a seamless interface into the on‐board system. SpaceWire is the result of the e orts of many individuals within the European Space Agency, European Space Industry and Academia. SpaceWire is being widely used on many space missions by: ESA / NASA / JAXA / CNSA SpaceWire is de ned in the European Cooperation for Space Standardization ECSS-E50-12A standard. Technical Data ECSS-Q-ST-70-08 Space product assurance —Manual soldering of high reliability electrical connections ECSS-Q-ST-70-26 Space product assurance — Crimping of highreliability electrical connections ANSI/TIA/EIA-644 1995 Telecommunications Industry Association, “Electrical Characteristics of Low Voltage Di erential Signaling (LVDS) Interface Circuits”, March 1996 ESCC 3401/071 Connectors, Electrical, Rectangular, Microminiature, Solder Bucket Contacts with EMI Backshell, based on type MDM Connectors The SpaceWire connector has eight signal contacts plus a screen termination contact. A ninepin micro- miniature Dtype is speci ed as the SpaceWire connector. This type of connector is available quali ed for space use. SpaceWire connector contact identi cation The following test report gives a relevant basis to establish a clear comparison of electrical perfor- mances between the actual SpaceWire quali ed connector couple and the insertion of PLUG IN feed through developed for AIT testing in vacuum chambers. As we can see on the eye patterns, we have a good margin with the mask limits for all the tested pin couples (1&6, 9&5, 2&7, 8&4) for all the tested feed throughs in worst case condition with maximum datarate (400Mb/s) and minimum voltage from emitter (250mV). 38
