10/100/1000BASE-T GIGABIT COPPER TRANSCEIVER
FEATURES
SUMMARY OF BENEFITS
• Fully-integrated 10BASE-T/100BASE-TX/1000BASE-T Gigabit
Ethernet transceiver
• GMII, RGMII, RTBI, and MII MAC Interface options
• On-chip low-voltage regulators
• Fully compliant with IEEE 802.3, 802.3u, and 802.3ab standards
• 0.13µ CMOS—low power and cost
• Low power
- Less than 700 mW per port
- Wake on LAN support
- Advanced power management
• Trace matched output impedance
• Line-side loopback
• Low EMI emissions
• Cable-plant diagnostic
- Cable-plant analyzer function detects cable plant impairments
- Link quality indication LED
- Automatic detection and correction of wiring pair swaps, pair skew,
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
• 128-pin MQFP, 117-pin BGA, and 100-pin FBGA packages
• Simplifies system and board design.
- Reduced I/O pin requirements with RGMII (over 50%).
- Clock timing can be adjusted to eliminate board trace delays
required by the RGMII specification.
• Provides interoperability with IEEE standard devices operating at 10,
100, and 1000 Mbps at half- and full-duplex.
• Lowers system BOM cost and simplifies system design.
• Requires no airflow or heatsink.
• Provides compliance with PCI 2.2 and PC99/PC2000.
• Eases system level debug.
• Reduces system design constraints to meet EMI emissions standards.
• 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.
