100 BASE-TX/FX

REPEATER CONTROLLER

1.0 FEATURES

• Eight 100 BASE-TX/FX ports; each port individually

configurable to TX or FX

• Management features accessible through MII or se-

rial ports

• Direct interface with analog clock generation/recov-

ery chips

• All ports can be separately isolated or partitioned in

reponse to fault conditions

• Three Media Independent Interface (MII)

• Expandable to increase number of repeater ports

• LowlatencydesignsimplifiedhighportnumberClass

II repeater implementation

• Conforms to IEEE 802.3u Repeater Unit Specifica-

tion

• LED display for TX/FX port activities and collisions

• 208-pin, CMOS device in PQFP package

2.0 GENERAL DESCRIPTION

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.

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.
