DP83820 - 10/100/1000 Mb/s PCI Ethernet Network Interface Controller

General Description

DP83820 is a single-chip 10/100/1000 Mb/s Ethernet Controller for the PCI bus.

It is targeted at highperformance 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.

Key Features

  • IEEE 802.3 Compliant, 66/33 Mhz, 64/32-bit PCI V2.2 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.
  • Flexible, programmable Bus master - burst sizes of up to 256 dwords (1024 bytes).
  • BIU compliant with PC 97 and PC 98 Hardware Design Guides, PC 99 Hardware Design Guide draft, ACPI v1.0, PCI Power Management Specification v1, OnNow Device Class Pow.
