Low power quad-port integration enables single-row,

high port density switches.

• Lowers system costs by eliminating PCB layers required for

• SGMII interface reduces I/O pin requirement over RGMII by

• Lowers MAC/switch costs by reducing the number of pins

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.

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.
