EasyPlug™ CompactPCI Backplane

Two 2 oz. copper voltage planes allow us to maximize power distribution while they act as virtual ground planes for the signals in order to minimize noise and crosstalk.

There is also a full VI/O plane. We use stripline construction to assure the highest possible performance. By exclusively utilizing stripline construction, we eliminate a

significant source of EMI/RFI radiation and give all the signals similar characteristic impedances, virtually identical propagation delays, and minimal signal skew. All

these items allow for significantly higher data transfer rates, as signal skew factors into the data transfer rate calculations four times.

User Manual for Bridgeable Backplanes

Background

CompactPCI bridging was developed to circumvent the 9-load limitation on 8-slot boards. The CPU board generates two loads and the I/O boards generate one load

each. The bridgeboards put an extra load on a slot; therefore, the segments are limited to seven loads. Bridgeboards provide up to 256 CompactPCI segments in a

system. The segment containing the CPU board is called the primary or upstream segment. The segment on the other side of the bridgeboard is called the secondary

or downstream segment.

Installation

14-slot cPCI: The bridgeboard is installed on the rear side of the backplane, covering slots 5 through 8. Place the unit on slot 5 rP1 and rP2 and slot 8 rP1 and rP2.

16-slot cPCI: The bridgeboard is installed on the rear side of the backplane, covering slots 4 through 9. Place the unit on slot 4 rP1 and rP2 and slot 9 rP1 and rP2.

Notes

JP1 - - JP1 is the jumper for +5V operation and JP2 for +3.3V operation.
