DP83820

General Description

DP83820 is a single-chip 10/100/1000 Mb/s Ethernet

Controller for the PCI bus. It is targeted at high-

performance adapter cards and mother boards. The

DP83820 fully implements the V2.2 66 MHz, 64-bit PCI bus

interface for host communications with power management

support. Packet descriptors and data are transferred via

bus-mastering, reducing the burden on the host CPU. The

DP83820 can support full duplex 10/100/1000 Mb/s

transmission and reception.

Features

— IEEE 802.3 Compliant, 66/33 Mhz, 64/32-bit PCI V2.2

— Flexible, programmable Bus master - burst sizes of up to

— BIU compliant with PC 97 and PC 98 Hardware Design

— Wake on LAN (WOL) support compliant with PC98,

— GMII/MII provides IEEE 802.3 standard interface to

— Ten-Bit Interface (TBI) for support of 1000BASE-X

System Diagram

MAC/BIU supports data rates from 1 Mb/s to 1000 Mb/s.

This allows support for traditional 10 Mb/s Ethernet, 100

Mb/s Fast Ethernet, as well as 1000 Mb/s Gigabit

Ethernet.
