Technical Information

VME64x Backplanes

All WIENER VME 64x multi-layer backplanes are outfitted with 5-row 160 pin connectors for J1 and J2 as well as optionally with 133 pin hard metric connector for J0.  The busses have active on board termination and active automatic daisy-chain (CBLT compatible!). Available with  up to 21 slots.
W-Ie-Ne-R’s special current multilayer made of  “z”-bended copper sheets, further stiffens the 4.8mm thick board.

  • Strip line technology suitable for data rates of 320Mbyte/s (64bit)
  • High power distribution by current multiplayer / bus bar system
  • Excellent RF shielding
  • Optimized filtering (electrolytic and ceramic filter-capacitors)
  • Minimized ground shift and cross talk
  • Automatic daisy chain
  • flat cable connector for sense and control
  • Provision for up to 8 temperature sensors (module temp. checking)
  • Sense circuit protection by PTC- resistors (Optionally)
  • Special version for VIPA (VME in Physics) and CERN VME430 style
