Connections Between Devices
(Cascading)
Connections Between Boards
(Stacking)
Local
Connect all.
Do not connect
.
Stack
For devices with FPS = 0, pull-up at each device
and
do not interconnect
.
Connect devices with FPS = 0 between boards.
Use one pull-up resistor per stack.
Full
Connect all.
Connect using buffers.
Digital IRB signals include IRnDAT, IRnCOL, IR10COLBP, IRnENA and IRnCLK.
Local Analog IRB signal: IRnCFS.
Inter-Board Analog IRB signal: IRnCFSBP.
HOLDCOL is used on the 10Mbps IRB Only.
This diagram shows a single IRB. The LXT98x3 actually has two independent IRBs, one per speed/segment.
