®
10/100/1000BASE-T GIGABIT COPPER TRANSCEIVER WITH SERDES
FEATURES
•
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
SUMMARY OF BENEFITS
•
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.
•
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
•
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
•
Ethernet@WireSpeed™ logic automatically selects the
maximum speed based on channel conditions

pairskew, and pair polarity
•
Automatic MDI/MDIX crossover at all speeds
•
Robust CESD tolerance
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.
•
