•
Low power
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.

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.
