Backplane Catalogue - Elma Electronic - #39

VME64x is an extension of the VME64 standard ANSI-VITA 1-1994 and permits 64-bit data traffic. It defines a set of features that can be added to VME and VME64 boards, backplanes, and subracks. The major new fea­tures include expanded 160-pin P1/J1 and P2/J2 con­nectors, an optional 95-pin (2-mm hard metric P0/J0 connector) for more user-defined I/O, +3.3 V and auxiliary power voltage, plus more +5 V power. The VME64x system is downward-compatible, so that assemblies with 96-pin connectors to DIN 41612 can still be used. Mechanical aspects of VME64x include support for EMC protection, ESD protection, solder side covers, an injector/extractor handle with locking, and board keying to specific subrack slots.

The VME64x extender board supports daughter board testing. It is plugged into the backplane in the slot for the daughter board. The daughter board is plugged onto the extender board outside the card container, making it more easily accessi­ble. All contacts with the backplane can be control­led individually by jumpers. Configured for 6U backplanes with 160 mm card depth, the extender board is available with connectors for J1/J2/J0 and for J1/J2. The test sector offers easy access, with tapping points right and left of the jumpers for all signal lines (and J0). GND, +3.3 V, +5 V, +12 V and -12 V are linked to power layers and each is accessible through a Faston connector.
