BCM5434 System Diagram
•
Low power quad-port integration enables single-row,
high port density switches.
•
Lowers system costs by eliminating PCB layers required for
routing high density solutions
•
SGMII interface reduces I/O pin requirement over RGMII by
more than 50%.
•
Lowers MAC/switch costs by reducing the number of pins
required to interface to the PHY.
•
Provides compatibility with IEEE standard devices
operating 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.
