DP83891 Gig PHYTER™
10/100/1000M
General DescriptionThe DP83891is the first fully integrated, feature rich Physi-
cal Layer transceiver with integrated PMD sublayersto sup-
port 10BASE-T,100BASE-TX and 1000BASE-T Ethernet
protocols. It operates on existing CAT5 cables which
reduces deployment costs.
The DP83891is designed for easy implementationof
10/100/1000 Mb/s Ethernet LANs.It interfaces directlyto
Twisted Pair media viaan external standard Quad trans-
former. The DP83891 connectsto the MAC layer through
the IEEE 802.3u Standard Media Independent Interface
(MII)or the IEEE 802.3z Gigabit Media Independent Inter-
face (GMII).
ApplicationsThe DP83891 fits applications in: 10/100/1000 Mb/s capable node cards Switches with 10/100/1000 Mb/s capable ports High speed uplink ports (backbone) High end workstations
