10/100/1000BASE-T GIGABIT COPPER TRANSCEIVER WITH SERDES
FEATURES
SUMMARY OF BENEFITS
• Fully integrated 10BASE-T/100BASE-TX/1000BASE-T
Gigabit Ethernet transceiver with SerDes
• MII, GMII, TBI, RGMII, RTBI, SGMII, and MAC SerDes
interface options
• Line-side copper and fiber interface options
• On-chip low voltage regulators
• Fully compliant with IEEE 802.3, 802.3u, and 802.3ab
standards
• 0.13-µm CMOS — low power and cost
• Low power
• 1W per port
• Wake on LAN support
• Advanced power management
• Low EMI emissions
• Ethernet@WireSpeed™ logic automatically selects the
maximum speed based on channel conditions
• Cable plant diagnostic
• Cable plant analyzer function detects cable plant impairments
• Link quality indication LED
• Automatic detection and correction of wiring pair swaps,
pairskew, and pair polarity
• Automatic MDI/MDIX crossover at all speeds
• Robust CESD tolerance
• Support for jumbo packets up to 9 KB
• IEEE 1149.1 (JTAG) boundary scan
• 117-pin BGA and 128-pin MQFP packages
• Provides triple-speed operation for compatibility with legacy
networks.
• Simplifies system and board design.
• RGMII/RTBI reduces I/O pin requirement over GMII and TBI
by more than 50%.
• SGMII further reduces the interface to six pins, while the serial
• MAC SerDes interface requires only four pins.
• Lowers system cost and reduces solution footprint.
• Provides interoperability with IEEE standard device
operation at 10, 100 and 1000 Mbps at half- and full-duplex.
• Requires no airflow or heatsink.
• Provides compliance with PCI 2.2 and PC99/PC2000.
• Reduces system design constraints to meet EMI emissions
standards.
• Automatically configures the link to support the highest
possible speed based on link partner capability and
characteristics of the channel.
• 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.
• High 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.
