10/100/1000BASE-T GIGABIT ETHERNET TRANSCEIVER

Complete 10/100/1000BASE-T Network Interface Card (NIC) Solution

• Fully integrated 10BASE-T/100BASE-TX/1000BASE-T

Gigabit Ethernet transceiver

• IEEE 802.3, 802.3u, and 802.3ab standards

• Digital Signal Processor (DSP) based design offering robust,

fully adaptive performance and simplified board design

• Field-proven design based on the BCM5400

• Register and software compatible with the BCM5400

• Advanced power management

• Low-power 1.8V digital core

• Wake on LAN support

• Integrated cable test features

• Link quality indication

• Automatic detection and correction of wiring pair swaps, pair

skew, and pair polarity

• Automatic MDI crossover

• IEEE 802.3ab standard auto-negotiation with next page

support to determine operating speed

• Internal 125-MHz low-jitter clock generation

• GMII interface and 10-bit interface (TBI)

• Support for jumbo packets up to 9 KB

• JTAG test interface

• 256-pin TBGA package

• Provides robust operation at 1000 Mbps on existing CAT 5

cable plants.

• Supports 10/100/1000BASE-T applications.

• Dynamically senses and adapts to changes in the channel

conditions of the cable plant.

• Backward software compatibility with, and similar layout to,

the BCM5400 allows easy migration to the newest technology.

• Does not require heat sink or airflow.

• Allows characterization of cable plant and immediate

indication of cabling issues for 1000BASE-T.

• Simplifies installation and diagnostics of cable plants.

• Automatically configures the link to support the highest

possible speed (10/100/1000 Mbps and full-duplex or half-

duplex operation).

• 125-MHz clock eliminates costly external clocking circuitry for

the MAC/ASIC.

• Compatible with any existing MAC/ASIC that supports either

an industry-standard 10-bit interface (TBI) or IEEE 802.3z

standard GMII.

• Flexible and programmable LED support.

• Includes visual link quality indicator
