3.8.1
IRB Signal Types
IRB signals can be characterized by the following connection types (For Stacking and Cascading
connections, see
Table 19 on page 50
):
Local
—
connected between devices on the same board
Stack
—
connected between boards
Full
—
connected between devices in the same board
and
between boards.
3.8.2
IRB Isolation
The ISOLATE outputs (IR10ISO and IR100ISO) are provided to control the enable pins of external
bidirectional transceivers. In stacking applications, they can be used to isolate one board from the
rest of the stack. Only one device can control these signals. The output states of these pins are
controlled by the Isolate bits in the Repeater Configuration Register.
3.8.3
10 Mbps-Only Operation
3.8.3.1
MAC IRB Access
The MACACTIVE pin allows an external MAC or other digital ASIC to interface directly to the
10 Mbps IRB. When the MACACTIVE pin is asserted, the LXT98x0 drives the IR10CFS and
IR10CFSBP signals on behalf of the external device, allowing it to participate in collision detection
functions.
3.8.3.2
Management Master Chain Arbitration
This daisy chain is provided for correct statistics gathering in 10 Mbps cascaded configurations. In
stacked applications, this daisy chain must be maintained through cascades. In stand-alone
applications, or for the first device in a chain, the MMSTRIN input must be pulled Low for the
management counters to work correctly.
3.8.4
LXT98x/91x/98x0 Compatibility
The LXT98x0 devices feature low-power 3.3V design. The LXT98x and LXT91x devices operate
at 5V and are incompatible with the LXT98x0 devices in cascades. The LXT98x0 devices,
however, are
backwards stackable
with LXT98x and LXT91x repeaters.
