The DP83843BVJE is a full feature Physical Layer device.
IEEE 802.3 ENDEC with AUI/10BASE-T transceivers with integrated PMD sublayers to support both 10BASE-T and built-in filters and 100BASE-X Ethernet protocols.
IEEE 802.3u 100BASE-TX compatible - directly drives standard Category 5 UTP, no need for external This VLSI device is designed for easy implementation of 100BASE-TX transceiver 10/100 Mb/s Ethernet LANs. It interfaces directly to Twisted Pair media through an extern.
