DM9081

10BASE-T Hub Controller

Final

1

Version: DM9081-DS-F02

February 02, 2001

General Description

The 10BASE-T Hub Controller (DM9081) provides a

system level solution for designing IEEE-compliant

802.3 repeaters that incorporate 10BASE-T

transceivers. This device integrates the repeater

functions specified by section 9 of the IEEE 802.3

standard. The Twisted Pair transceiver is compliant

with 10BASE-T standards. The DM9081 provides

eight integral Twisted Pair Media Attachment Units

(MAUs) and two Attachment Unit Interface (AUI)

ports in a 100-pin QFP package.

The total number of ports per repeater unit can be

increased by connecting multiple DM9081 chips via

their expansion ports. The DM9081 supports LED

drivers to monitor port status. It displays Link, Carrier

Sense, Collision, Partition, and Bit Rate Error Status.

In minimum mode, Link, Carrier Sense, and Collision

Status can be displayed without external TTL

devices.
