MMSTRIN, MMSTROUT
This daisy chain is provided for correct gathering of statistics in multiple-device configurations. In
multiple-board applications, this daisy chain must be maintained across boards. In stand-alone
applications, or for the first device in a chain, the MMSTRIN input must be pulled Low in order for
the management counters to work correctly.

(same board)
Connections Between Boards
Full
Connect all.
Connect using buffers.
Local
Connect all.
Do not connect.
Stack
For devices with ChipID
≠
0, pull-up at each
device and
do not interconnect.
Connect devices with ChipID = 0 between boards.
Use one pull-up resistor per stack.
Special (xxISO)
For devices with ChipID
≠
0, leave open.
For device with ChipID
=
0, connect to buffer
enable.
Do not connect.

Digital IRB signals include IRnDAT, IRnENA and IRnCLK.
Local Analog IRB signals include IRnCOL and IRnCFS.
Inter-Board Analog IRB signals include IRnCOLBP and IRnCFSBP.
HOLDCOL is used on the 10Mbps IRB Only.
This diagram shows a single IRB. The LXT980 actually has two independent IRBs, one per speed/segment.
