2.0 GENERAL DESCRIPTION
The MX98741 (100BASE-TX Repeater Controller, XRC)
is a 208-pin PQFP device that interfaces directly with
offshell clock generation/recovery chips. Eight ports can
be configured as 100 BASE-TX or FX ports individually.
Three additional ports have Media Independent Inter-
faces (MII) which allow easy connection of management
and bridge devices. The expansion port allows multiple
XRCs to be linked together to form a repeater of high
port counts. LEDs are provided for visual monitoring of
TX/FX port activities and collisions.
The XRC's design inserts minimum delay between the
TX/FX ports and the expansion port. A master-slave
type arbitration is also implemented to shorten the
communciation time among multiple XRCs. As a re-
sult, design for Class II stackable hub is greatly simpli-
fied.
Control Functions and management status are imple-
mented through internal registers. These registers are
accessed via either standard MII management interface
(MDC, MDIO) or several serial ports. These serial ports
are accessed easily by hardware for debugging and
configuration purposes. A dedicated management chip
can also utilize these serial ports to access the XRC.
