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.
