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 100BASE-X Ethernet protocols.

and built-in filters

— IEEE 802.3u 100BASE-TX compatible - directly drives

standard Category 5 UTP, no need for external

100BASE-TX transceiver

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 Inde-

pendent Interface (MII), ensuring interoperability between

products from different vendors.

— Fully Integrated and fully compliant ANSI X3.263 TP-

PMD physical sublayer which includes adaptive equal-

ization and BLW compensation

— IEEE 802.3u 100BASE-FX compatible - connects direct-

ly to industry standard Electrical/Optical transceivers

— IEEE 802.3u Auto-Negotiation for automatic speed se-

lection

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 802.3u compatible Media Independent Interface

(MII) with Serial Management Interface

— Integrated high performance 100 Mb/s clock recovery

circuitry requiring no external filters

— IEEE 802.3 ENDEC with AUI/10BASE-T transceiver

module to provide the 10 Mb/s functions

— Full Duplex support for 10 and 100 Mb/s data rates

— MII Serial 10 Mb/s mode

— Clock Recovery/Generator Modules from National's Fast

Ethernet and FDDI products

— Fully configurable node/switch and 100Mb/s repeater

modes

— FDDI Stream Cipher scrambler/descrambler for

TP-PMD

— Programmable loopback modes for flexible system diag-

nostics

— 100BASE-X physical coding sub-layer (PCS) and control

logic that integrates the core modules into a dual speed

Ethernet physical layer controller

— Flexible LED support

— ANSI X3T12 Compliant TP-PMD Transceiver

— Single register access to complete PHY status

— MDIO interrupt support

technology with Baseline Wander (BLW) compensation

— Individualized scrambler seed for 100BASE-TX applica-

tions using multiple PHYs

— Low power consumption for multi-port applications

— Small footprint 80-pin PQFP package
