FEATURES

Dual-port integrated 10BASE-T/100BASE-TX/1000BASE-T 

Gigabit Ethernet transceiver .

• RGMII, SGMII, and SerDes MAC interface options.

• 1-Gbps line-side SerDes with RGMII MAC interface.

• Fully compliant with IEEE 802.3, IEEE 802.3u, and 

IEEE 802.3ab standards.

• 0.13-micron CMOS—low power and cost.

• Supports copper or fiber in RGMII mode.

• Low power.

• 600 mW per port.

• Advanced power management.

• 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.

• Support for jumbo packets up to 10 kB

 SUMMARY OF BENEFITS

Low-power, dual-port integration reduces design constraints 

for space-constrained IP phone applications.

• Compact solution for 10/100Base-TX uplink applications.

• 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.

• Lowers system BOM cost and simplifies system design.

• Eases system level debugging.

• Enables use of low-cost magnetics.

• 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.

• Ease of manufacturing with JTAG support, simplified power 

supply, and multiple MAC interfaces.
