Description
The integration of a dual LVDS receiver and transmitter into one package, meeting the space radiation, cold-sparing and capable of handling large common mode signals, is a necessity to meet the increasing demand for robust SpaceWire communication in satellites. In the frame of an ESA activity under the European Component Initiative (ECI) program, Cobham-Gaisler has undertaken the development of such LVDS transceiver, ideally suited for SpaceWire links, to complement its product range of SpaceWire products. The scope of the LVDS transceiver development will be presented together with the architecture of the LVDS transceiver. The specific implementation issues pertinent to the reliable operation of the SpaceWire link operation in space like the receiver input hysteresis, embedded active fail-safe circuitry, cold-spare and 8kV ESD protected IO's in addition to applied radiation mitigation methodology will be discussed. Finally the relevant prototype electrical and radiation test results will be presented.
