®
DUAL-PORT 10/100/1000BASE-T GIGABIT ETHERNET TRANSCEIVER
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.
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.
•
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.
•
Eases system level debugging.
•
Enables use of low-cost magnetics.
•
Cable diagnostic function characterizes cable plant condition
and immediately indicates cabling issues.
•

•
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.
