Schroff has introduced a range of 64-bit CompactPCI backplanes compliant with PICMG 2.0 Rev. 3.0. Suitable for 6U CompactPCI hot-swap boards, they are available as 2, 4, 6 and 8 slot versions (1, 2, 3 and 4U), and are constructed as continuous monolithic 9U units, with an integral 3U wide area for plug-in power supplies. The monolithic construction avoids the voltage losses associated with power cables and connectors. Up to four CompactPCI power supplies can be accommodated, operating in parallel or redundantly. The backplanes are arranged as ten-layer boards with ceramic capacitors in SMD technology. The geographic address of the backplane is determined, but can easily be changed by the user with SMD Zero Ohm resistors.
