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 .
• 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.
• IEEE 1149.1 (JTAG) boundary scan.
• 121-pin BGA package.
• 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.
