DUAL-PORT 10/100/1000BASE-T GIGABIT ETHERNET TRANSCEIVER
FEATURES
SUMMARY OF BENEFITS
• _{Dual-port integrated 10BASE-T/100BASE-TX/1000BASE-T}
Gigabit Ethernet transceiver
• _{Compact solution for high density uplink applications, enabling}
10/100/1000BASE-T and 1000BASE-X/100BASE-FX uplinks
• _{RGMII, SGMII, and SerDes MAC interface options}
• _{SGMII to SGMII support for SFP modules}
• _{Fully compliant with IEEE 802.3™, IEEE 802.3u, IEEE 802.3ab}
standard, and IEEE 802.3z
• _{0.13-micron CMOS—low power and cost}
1000BASE-X and 100BASE-FX support from same line side pins
enables direct interface to SFP modules
• _{Provides compatibility with IEEE standard devices operating at}
10, 100, and 1000 Mbps at half-duplex and full-duplex.
• _{Clock timing can be adjusted to eliminate board trace delays}
required by the RGMII specification.
• _{Supports copper or fiber in RGMII mode}
• _{Lowers system BOM cost and simplifies system design}
• _{Low power}
• 725 mW per port
• Advanced power management
• _{Eases system level debugging}
• _{Enables use of low-cost magnetics}
• _{Trace-matched output impedance}
• _{Line-side and MAC-side loopback}
• _{Low EMI emissions}
• _{CableChecker™ diagnostics}
• Cable plant analyzer function detects cable plant impairments
• Ethernet@WireSpeed
• Automatic MDI/MDIX crossover at all speeds
• _{Robust cable-sourced electrostatic discharge (CESD) tolerance}
• _{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
• Allows immediate uptime at reduced speeds (100BASE-TX or
10BASE-T)
• _{Over 3 kV of CESD tolerance prevents equipment damage and}
return.
• _{Operates with larger packets for wider range of packet protocol}
support and improved efficiency
• _{Support for jumbo packets up to 10 kB}
• _{IEEE 1149.1 (JTAG) boundary scan}
• _{Ease of manufacturing with JTAG support, simplified power}
supply, and multiple MAC interfaces
• _{121-pin BGA package}
