Description

The DP83864 is an extremely efficient full featured Quad Physical Layer transceiver with integrated PMD sublayers to support 10BASE-T, 100BASE-TX and 1000BASE-T Ethernet protocols.

The DP83864 contains four integrated  ultra  low power Gigabit Physical layers. It uses advanced 0.18 m, 1.8 V
CMOS technology, fabricated at National's South Portland,Maine facilities.

The DP83864 is designed for easy implementation of 10/100/1000 Mb/s Ethernet LANs. Each port interfaces directly to Twisted Pair media via an external transformer. This device interfaces directly to the MAC layer through the IEEE 802.3u Standard Media Independent Interface (MII) or the IEEE 802.3z Gigabit Media Independent Interface (GMII). It also supports the reduced pin count RGMII (12 pins per port) and serial GMII (8 pins per port).

The DP83864 is a fourth generation of Gigabit Physical layer product with field proven architecture and perfor-mance.  Its robust performance ensures drop in replace-ment of existing 10/100M equipment with 10/100/1000M Networking infrastructure.
