CPCI Bridges 23006-920 & -922
Assembly Instructions & General Information
1. Mechanical Mounting:
but not fixed. The mounting screws of the backplane are not to be tightened until the bridge is
plugged and fully seated!
2. Power Supply of Backplanes:
The bridge is not to be used for bridging power.
The bridge does not isolate the power rails of both backplanes.
GND is connected by a sufficient number of pins in the connector to ensure signal integrity and a common
GND potential on both backplanes.
3. VI/O: There is no need to choose the VI/O voltage for the bridge. The bridge automatically takes the VI/O
voltage of the primary and secondary side.
Both backplanes can be set to different VI/O voltages, e.g. +5V on the primary side and 3,3V on the
secondary side.
4. M66MHz Operation:
Bridge 23006-920 is capable of 33MHz Operation.

Please make sure that both backplanes are only attached to the horizontal rails,
Both backplanes connected by the bridge are to be powered individually.
