DP83865BVH Gig PHYTER^®V

10/100/1000 Ethernet Physical Layer

General Description

Features

The DP83865 is a fully featured Physical Layer transceiver ■ Fully compliant with IEEE 10BASE-T, 100BASE-TX and

with integrated PMD sublayers to support 10BASE-T,

100BASE-TX and 1000BASE-T Ethernet protocols.

1000BASE-T specifications (802.3u, 802.3z, 802.3ab).

■ Integrated PMD sublayer featuring adaptive equalization

and baseline wander compensation according to ANSI

X3.T12.

The DP83865 is an ultra low power version of the DP83861

and DP83891. It uses advanced 0.18 um, 1.8 V CMOS

technology, fabricated at National Semiconductor’s South

Portland, Maine facility.

■ 3.3 V or 2.5 V MAC interfaces:

– IEEE 802.3u MII

The DP83865 is designed for easy implementation of

10/100/1000 Mb/s Ethernet LANs. It interfaces directly to

Twisted Pair media via an external transformer. This device

– IEEE 802.3z GMII

■ User programmable GMII pin ordering.

interfaces directly to the MAC layer through the IEEE ■ IEEE 802.3u Auto-Negotiation and Parallel Detection

802.3u Standard Media Independent Interface (MII) or the

IEEE 802.3z Gigabit Media Independent Interface (GMII).

and 10 Mb/s full duplex and half duplex devices

– Fully Auto-Negotiates between 1000 Mb/s, 100 Mb/s,

The DP83865 is a fourth generation Gigabit PHY with field

proven architecture and performance. Its robust perfor-

mance ensures drop-in replacement of existing 10/100

Mb/s equipment with 10/100/1000 Mb/s networking infra-

structure.

■ LED support for activity, full / half duplex, link1000,

link100 and link10 or user programmable (manual

on/off).

■ Supports 25 MHz operation with crystal or oscillator.

■ Requires only two power supplies, 1.8 V (core and ana-

log) and 2.5 V (analog and I/O). 3.3V is supported as an

alternative supply for I/O voltage.

Applications

The DP83865 fits applications in:

■ User programmable interrupt.

■ 10/100/1000 Mb/s capable node cards

■ Switches with 10/100/1000 Mb/s capable ports

■ High speed uplink ports (backbone)

■ Supports Auto-MDIX at 10, 100 and 1000 Mb/s.

■ Supports JTAG (IEEE1149.1).

■ Ultra low power consumption of one watt typical.

■ Management port (MDC / MDIO).

■ 128-pin PQFP package (14mm x 20mm).

■ WOL support.
