BCM5402 System Diagram
Low power dual-port integration enables high port
density switches and dual-port adapter cards.
Compatible with IEEE standard devices operating 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 per-port).
RGMII/RTBI reduces I/O pin requirement over GMII
and TBI by more than 50%.
Automatically configures the link to support the
highest possible speed based on link partner capability
and characteristics of the channel.
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 improved efficiency.
High density package options without heatsink
requirement provides improved testability.
