DM9081

10BASE-T Hub Controller

Features

ꢀRepeater functions comply with IEEE 802.3

Repeater Unit specification

ꢀBuilt-in Traffic LED indicates Hub global 10MHz

bandwidth utilization status

ꢀEight Integral 10BASE-T transceivers utilize the

required pre-distortion transmission technique

ꢀTwo Attachment Unit Interface (AUI) ports allow

connection with 10BASE5 (Ethernet) and

10BASE2

ꢀExpandable to accommodate two DM9081

connections, with no external logic required

ꢀOn board PLL, Manchester encoder/decoder and

FIFO

ꢀExpandable to accommodate increased number of

repeater ports. Recommended IC cascade number:

under 3 and inclusive

ꢀPreamble loss effects eliminated by deep FIFO

ꢀEach port can be isolated (partitioned) and

reconnected separately

ꢀTwisted Pair Link Test capability

ꢀFull amplitude and timing regeneration for

retransmitted signals

(Cheapernet) networks

ꢀDesign a Dumb Hub in minimum mode by using

minimum external logic that can respond to Link,

Carrier Sense and Collision Status from LED

ꢀSupports one LED output per port for additional

status indicators such as Link, Partition, Carrier

Sense, etc.

ꢀBuilt-in Jabber LED reports global Jabber

information of the DM9081 Hub

ꢀLow power CMOS process with single 5V supply

ꢀ100-pin QFP package
