MEDIA INTERFACE
FEATURES
SUMMARY OF BENEFITS
• Four fully integrated 10BASE-T/100BASE-TX/1000BASE-T
Gigabit Ethernet transceivers
• GMII, RGMII, SGMII, and SerDes MAC interface options
• Copper or SerDes line interface options
• Fully compliant with IEEE 802.3, 802.3u, and 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 diagnostic
• 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: 354-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 to 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
• Requires no air flow or heat sink
• 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 4kV 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
