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.
