VXIbus CLK10 Routing for a Two-Frame System
The VXI-MXI-2 in Frame A routes CLK10 from the VXIbus to the
MXIbus. The Slot 0 device in Frame A is responsible for generating
CLK10 in that frame.
The VXI-MXI-2 in Frame B routes CLK10 from the MXIbus to the
VXIbus, which allows CLK10 to be synchronous between the two
frames.
Notice that the VXI-MXI-2 in Frame B must be the Slot 0 device in
that frame. Otherwise, it could not drive CLK10 on the backplane.
