CompactPCI Backplanes

Our standard range of high performance, hot swap, CompactPCI backplanes are available in 3U, 6U & 9U form factors and from 2 to 16 slots wide*. The generic base design allows many different product configurations to be realised (32/64Bit, 33/66MHz, left/right system slot, 5v/3.3v I/O signalling voltage and rear connections, power options etc.) making them suitable for a wide range of end user applications. * Note: A rear pallet bridge is required for backplanes above 8 slots wide – these are included with the backplane

PICMG 2.16 supplements the robust, reliable and hot-swap capable CompactPCI architecture with the easily integrated, low-cost, high performance, and extensible Ethernet. The 2.16 specification extends rather than replaces CompactPCI because it over-lays, on the P3 connector, up to two embedded switched Ethernet networks in a star-topology. Slots can be routed either as “Fabric” or “Node” slots with a separate system / controller slot if required.

On CT/H.110 backplanes, the P4 connector is used for implementing the H.110 TDM bus signals as well as the telecom power rails and control signals. It has 3 different mating length pins and is selectively loaded in order to meet the hazardous voltage safety requirements. The P5 connector is used for telephony I/O with 3 mating levels provided according to the pin assignments.

Designed as a migration path to CPCI Serial (below), PICMG 2.3 adds fast serial data transfer, and is backward-compatible to CompactPCI (PICMG 2.0). It defines the pin assignment of the user-defined pins on the J2 connector (PICMG 2.0), sufficient for 4 PCI Express x1 links, 4 SATA, 4 USB 2.0, as well as 2 Ethernet 1000BaseT interfaces to the backplane. The new standard uses a different 2mm connector with 5 Gb/s to support the new high frequency signals. Even though signal pins are individually shielded and independent of the other pins, the connector is completely compatible to CompactPCI. This means a CompactPCI 2.3 CPU can be operated in a PICMG 2.0 system.

Whilst adopting some key, proven features of CompactPCI (PICMG 2), the cPCI-S.0 standard does away with the traditional PCI parallel bus completely and defines a point-to-point (serial) topology. The system slot provides 8 x PCI Express, SATA, USB (2&3) and Ethernet 10GBASE-T interfaces whilst the peripheral slots provide one of each of the above except Ethernet where up to 8 connections are offered. A different connector arrangement means there is no backward compatibility with PICMG 2.0.

The below table should be used to configure a unique part number for the CompactPCI backplane required. Note that not all combinations are possible and not all options are applicable.
