DP83843BVJE Datasheet | National Semiconductor

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 patible - 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 pliant 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 pensation MAC layer through the IEEE 802.3u standard Media Inde- IEEE 802.3u 100BASE-FX patible - 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 se The 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 patible Media Independent Interface (MII) with Serial Management Interface core technologies: - Integrated high performance 100 Mb/s clock recovery - IEEE 802.3 ENDEC with AUI/10BASE-T transceiver circuitry requiring no external filters module to provide the 10 Mb/s functions - Full Duplex support for 10 and 100 Mb/s data rates - Clock Recovery/Generator Modules from National's Fast - MII Serial 10 Mb/s mode Ethernet and FDDI products - Fully configurable node/switch and 100Mb/s repeater - FDDI Stream Cipher scrambler/descrambler for modes TP-PMD - Programmable loopback modes for flexible system diag- 100BASE-X physical coding sub-layer (PCS) and control nostics logic that integrates the core modules into a dual speed...
