Fully compliant with IEEE 802.3, 802.3u, and 802.3ab
• standards
• 0.13 um CMOS — low power and cost
• Low power
Low power quad-port integration enables single-row,
• high
port density switches.
• Low EMI emissions
logic automatically selects the

speed based on link partner capability
• 1W per port
• Advanced power management
TM
• Cable plant analyzer function detects cable plant impairments
• Link quality indication LED
• Automatic detection and correction of wiring pair swaps, pair
skew, and pair polarity
Automatic
MDI/MDIX crossover at all speeds
•
• Robust CESD tolerance
• Support for jumbo packets up to 9 KB
• IEEE 1149.1 (JTAG) boundary scan
• 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 fullduplex.
and characteristics of the channel.
Cable diagnostic function characterizes cable plant

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
