VXI Standard Revision to Meet Today's Technology Requirements

This standard describes the electrical and mechanical specifications of the IEEE-1155 VME extensions for Instrumentation (VXI) Standard that supports an integrated legacy parallel bus and serial bus architecture adopted from VME International Trade Association (VITA) Standard 41.3 [1], and LAN extensions for Instrumentation (LXI) Consortium [2]. It also addresses the definition of: (a) a C-size pluggable virtual power module; (b) the direct coupling option of the instrument module to the IEEE-P1505 receiver fixture interface (RFI) [3]; (c) enhanced cooling structure; (d) advanced VME controller/switch fabric modules; (e) VME64 connector compliance implementation; (f) improved noise and ripple isolation; (g) cooling air flow measurement; (h) IEEE-1149.1/4 test bus boundary scan/mixed signal [4]; and (i) LXI protocol/control line implementation. The specification also details: instrument module footprints, connector mechanics and electrical I/O between the backplane and instrument module, cooling/ EMI requirements; VXI mainframe mechanical structure, cooling and environmental requirements; and the VXI backplane mechanical and electrical requirements.
