Bridging Feature Links Backplanes Together

Features such as the ability to be bridged together, rear I/O, hot-swap capability, and PICMG 2.0 R3 compliance help qualify a new series of CompactPCI backplanes for use in 19" applications requiring high availability in tight quarters, such as encountered by telecomm and automation systems. In addition, by routing I/O to the P2 connector, the new 3U and 6U backplanes sidestep space constraints associated with routing signals from heavily loaded boards to the front. The backplanes are available in two- to eight-slot versions and can be mounted side-by-side without the loss of any slots by using a flat bridge located under the rear I/O boards. Both backplanes and bridge operate at up to 66 MHz. And by using extension backplanes, which are available in four- and seven-slot versions, a 19" chassis can accommodate as many as 21 slots. The backplanes also use high capacity ceramic capacitors to decouple the high frequency surge voltages common on new boards.
