10/100/1000BASE-T GIGABIT ETHERNET TRANSCEIVER
FEATURES
SUMMARY OF BENEFITS
• 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
