BCM5404 System Diagram
Low power quad-port integration enables single row,
high port density switches.
Provides compatibility with IEEE standard devices
operation at 10, 100, and 1000 Mbps at half- and full-
duplex.
Requires no airflow or heatsink.
Reduces design constraints in high-density
applications that have higher EMI emissions.
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.
High CESD tolerance prevents equipment damage and
return.
Operates with larger packets for wider range of packet
protocol support and improved efficiency.
Ease of manufacturing with JTAG support, simplified
power supply, and multiple MAC interfaces.
High-density package options:
Lowers system costs.
Simplifies system and board design.
RGMII/RTBI reduces I/O pin requirement over GMII and TBI
by more than 50%.
