BCM5411 System Diagram

Compatible with IEEE standard operation at 10, 100,
and 1000 Mbps at half- and full-duplex.

No airflow or heatsink required.

Wake on LAN mode for low-power, PC'99-compliant
adapters (less than 600 mW).

Auto-Network detection places unconnected ports into

low power state.

Automatically configures the link to support the

highest possible speed based on link partner capability
and characteristics of the channel.

RGMII/RTBI reduces I/O pin requirement over GMII
and TBI by more than 50%.

Cable diagnostic function characterizes cable plant
condition and immediately indicates cabling issues.

· Prevents erroneous equipment return due to bad cable plants.
· Prevents manufacturing fall-out due to bad cable plants.

125-MHz clock eliminates costly external clocking
circuitry for the MAC/ASIC.

Operates with larger packets for wider range of packet
protocol support and for improved efficiency.

High density package options without heatsink
requirement provides improved testability.
