COPPER/FIBER MEDIA INTERFACE
FEATURES
SUMMARY OF BENEFITS
• Four fully integrated 10BASE-T/100BASE-TX/1000BASE-T
Gigabit Ethernet transceivers
• RGMII, SGMII, and SerDes MAC interface options
• Copper or SerDes line interface options
• Fully compliant with IEEE 802.3, IEEE 802.3u, and
IEEE 802.3ab standards
• 0.13-micron CMOS—low power and cost
• Low power
• 750 mW per port
• Advanced power management
• Trace matched output impedance
• Line-side loopback
• Low EMI emissions
• Cable plant diagnostics
• 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 cable-sourced electrostatic discharge (CESD) tolerance
• Support for jumbo packets up to 10 kB
• IEEE 1149.1 (JTAG) boundary scan
• Package: 256-pin BGA
• 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 with the PHY.
• Flexibility for copper or fiber applications.
• Provides compatibility with IEEE standard devices operating
at 10, 100, and 1000 Mbps at half-duplex and full-duplex.
• 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 fallout due to bad cable plants
• Over 3kV 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.
