Description

The DP83861 is a full featured Physical Layer transceiver with integrated PMD sublayers to support 10BASE-T, 100BASE-TX and 1000BASE-T Ethernet protocols.

The DP83861 uses state of the art 0.18 m + 1.8 V/3.3 V CMOS technology, fabricated at National Semiconductor's South Portland Maine facility.

The DP83861 is designed for easy implementation of 10/100/1000 Mb/s Ethernet LANs. It interfaces directly to Twisted Pair media via an external transformer. This device interfaces directly to the MAC layer through the IEEE 802.3u Standard Media Independent Interface (MII) or the IEEE 802.3z Gigabit Media Independent Interface (GMII).
