Brief
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
