Backplane VXI-4

The WIENER 6U VXI-4 backplane is the first VXI bus available with features according to the new VXI-4 standard which add VME64x and VXS features into the VXI world. The backplane is fully compliant to VXI 1.4, VME rev. C.1, UL 796, and 94V-0 and implements the VME64x type connectors, 3.3V DC power and the LVDS lines LCLK100 and LSYNC100 as well as the LVDS Star Trigger from the VXI-4 standard.

This monolithic backplane in a 14 layer, all-strip line technology is outfitted with 5-row 160 pin HARTING connectors on J1 and J2. The backplane is actively terminated and provides active automatic daisy chaining which is compatible to the CBLT.

The extended power layers and special current rails permit highest power distribution. For power distribution and connection a flat sandwich-like structure of copper sheets is mounted on the back of the upper J1 area.
