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.
