Mixed Doubles: CompactPCI® Serial and CompactPCI® 2.0

2011-10-13, Barbara Schmitz

The first that comes to mind when thinking of building up hybrid systems is CompactPCI® PlusIO (PICMG 2.30). Here, the system slot CPU supports both the parallel CompactPCI® standard (PICMG 2.0) and the new CompactPCI® Serial standard (PICMG CPCI-S.0). Hybrid backplanes from different manufacturers enable configuration with peripheral slot boards on the left and on the right of the system slot board. Up to 7 parallel and a maximum of 4 serial boards are supported - without a bridge. This way, a cost-effective migration is possible, because the usage of future-oriented and standardized data transfer based on CompactPCI® Serial is guaranteed even when already integrated CompactPCI® components are used.

But what if none of the standard hybrid backplanes is suitable for the new application and/or more than 4 serial peripheral boards are needed and the lot sizes are too small for the development of a customer-specific backplane (in the beginning)?

In this case, the two worlds – CompactPCI® Serial und CompactPCI® – have to be connected in a different way. For this, one board pair is used. One board is the interface from Com-pactPCI Serial to CompactPCI® and is plugged into a peripheral slot of the CompactPCI® Serial backplane. The second interface board replaces the system slot CPU on the CompactPCI® backplane and is connected to the first interface board via a cable at the front panel. The new system slot board in the CompactPCI® system is equipped with a PCI Express® to PCI bridge, the communication over the cable is based on a PCI Express® x1 link. As both standards are compatible to the 19" mechanics, the solution can be accommodated in one rack. On the other hand PCI Express® enables cable lengths of up to 7 m so that two racks can also be coupled loosely.

If - for larger volumes - the development of a customer-specific backplane is profitable, the PCI-Express-based connection of CompactPCI® Serial to CompactPCI® can be done via rear I/O. This means that only the second interface board is needed which is plugged into the system slot of the CompactPCI® side.

This example shows once again how consequently CompactPCI® Serial follows up on its parallel predecessor. CompactPCI® Serial makes modern technology simple, robust, flexible and inexpensive - while the mechanics remain 100% compatible with CompactPCI® 2.0.
