VME J1 Backplanes, Series 129/130

  •  3U VME backplane with J1 connector:  2 to 21 slots

  • Slot pitch 4 HP (20.32mm)

  • Daisy Chain:  Automatic:  Electronic (with OR gates) or via mechanical connectors.  Manual; via wire-wrap posts

  • Active or passive termination

  • Optimized for best HF behavior.  Outer layers designed as shielding areas

  • PCB material FR-4, UL recognized 94-VO

  • Conforms to ANSI/VITA 1.1-1997

  •  RoHS compliant

Features at a Glance
  • Board design based on the HIGH-SPEED DESIGN concept.  Low reflection is achieved by means of uniform signal surge impedance
  • Shielding of each individual signal line assures minimal coupling, even when expanded to the 64-bit mode with the 2e protocol (160 Mbytes/s)
  • Backplanes come with active-IN-ON-BOARD termination.  Active and passive termination versions are available
  • Active termination offers reduced closed-circuit consumption, Passive termination offers better frequency response and wider temperature range
  • Backplanes come with Electronic Automatic Daisy Chaining (OR gates are integrated into the backplane) or via mechanical connectors
  • Electrically, the corresponding wiring is located at the end of the bus lines.  Mechanically, it is situated between the outermost slots in a space-saving design.
  • Solid electrically conductive chassis GND surface in the backplane to card rack area for EMC-tight mounting.  HF coupling of card rack and system ground is implemented by capacitors (10nF, 200V in each slot). 
  • A combination M6 screw/Faston 6.3 x .8mm is provided for chassis ground connection
  • Main operating voltage is supplies via terminal bars with M6 screws
  • Utility connector included for power supply and external LED’s
