DP83843 DP83843 PHYTER /LWHUDWXUH1XPEHU61/6% 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
