DP83843BVJE PHYTER July 1999 DP83843BVJE PHYTER General Description Features 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 external transformer or to fiber — Fully Integrated and fully compliant ANSI X3.263 TPmedia via industry standard electrical/optical fiber PMD PMD physical sublayer which includes adaptive equaltransceivers. This device also interfaces directly to the ization and BLW compensation MAC layer through the IEEE 802.3u standard Media Inde— IEEE 802.3u 100BASE-FX compatible - connects directpendent Interface (MII), ensuring interoperability between ly to industry standard Electrical/Optical transceivers products from different vendors. — IEEE 802.3u Auto-Negotiation for automatic speed seThe DP83843 is designed with National Semiconductor's lection advanced CMOS process. Its system architecture is based on the integration of several of National's industry proven — IEEE 802.3u compatible Media Independent Interface (MII) with Serial Management Interface core technologies: — Integrated high performance 100 Mb/s clock recovery — IEEE 802.3 E...
