Overview
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) DM9081 10BASE-T Hub Controller 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.
