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
• Reduced I/O pin requirements with RGMII (over 50%), SGMII
(over 75%), and SerDes (over 80%)
• Clock timing can be adjusted to eliminate board trace delays
required by the RGMII specification
• 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 at half-duplex
•

•
and full-duplex
Requires no airflow or heatsink
Lowers system BOM cost and simplifies system design
Eases system level debug
Enables use of low cost magnetics, even in high density
(48+) designs
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
Over 4 kV of 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
