The 6U monolitic WIENER J1/J2 backplane fully complies with the VME64 Extensions specification according to ANSI/VITA 1.1-1997 and 1.3-997. It is designed as a 10-layer board in strip-line technolgy. Monolithic VME64x backplanes are available with 7, 10 or 21 (full size) slots.
The backplane is actively terminated and provides active automatic daisy chaining. On request the active automatic daisy chain is available compatible to the CBLT.
The extended power layers and special current rails permit highest power distribution. The 21 slot monolithic J1/J2 backplane has more than 300A current capability on 5V, which corresponds to 15A per slot (at 70°C). For power distribution and connection a flat sandwich-like structure of copper sheets is mounted on the back of the upper J1 area. All DC wiring from this high-current multi-layer structure to the power supply situated in the bottom is integrated into the backplane layout by using the space between the connector shrouds.
