The DP83843BVJE is a full feature Physical Layer device with integrated PMD sublayers to support both 10BASE-T and 100BASE-X Ethernet protocols.

This VLSI device is designed for easy implementation of 10/100 Mb/s Ethernet LANs. It interfaces directly to Twisted Pair media through an external transformer or to fiber media via industry standard electrical/optical fiber PMD transceivers. This device also interfaces directly to the MAC layer through the IEEE 802.3u standard Media Independent Interface (MII), ensuring interoperability between products from different vendors.

The DP83843 is designed with National Semiconductor’s advanced CMOS process. Its system architecture is based on the integration of several of National's industry proven core technologies:

• IEEE 802.3 ENDEC with AUI/10BASE-T transceiver module to provide the 10 Mb/s functions
• Clock Recovery/Generator Modules fromNational's Fast Ethernet and FDDI products
• FDDI Stream Cipher scrambler/descrambler for TP-PMD
• 100BASE-Xphysical codingsub-layer (PCS) andcontrol logic that integrates the core modules into a dual speed Ethernet physical layer controller
• ANSI X3T12 Compliant TP-PMD Transceiver technology with Baseline Wander (BLW) compensation

• IEEE 802.3 ENDEC with AUI/10BASE-T transceivers and built-in filters
• IEEE 802.3u 100BASE-TX compatible - directly drives standard Category 5 UTP, no need for external 100BASE-TX transceiver
• Fully Integrated and fully compliant ANSI X3.263 TPPMD physical sublayer which includes adaptive equalization and BLW compensation
• IEEE 802.3u 100BASE-FX compatible - connects directly to industry standard Electrical/Optical transceivers
• IEEE 802.3u Auto-Negotiation for automatic speed selection
• IEEE 802.3u compatible Media Independent Interface (MII) with Serial Management Interface
• Integrated high performance 100 Mb/s clock recovery circuitry requiring no external filters
• Full Duplex support for 10 and 100 Mb/s data rates
• MII Serial 10 Mb/s mode
• Fully configurable node/switch and 100Mb/s repeater modes
• Programmable loopback modes for flexible systemdiagnostics
• Flexible LED support
• Single register access to complete PHY status
• MDIO interrupt support
• Individualized scrambler seed for 100BASE-TX applications using multiple PHYs
• Low power consumption for multi-port applications
