Four fully integrated 10BASE-T/100BASE-TX/1000BASE-T
Gigabit Ethernet transceivers
•
Low-power quad-port integration enables single-row,
high-port-density switches.
•
•
•
•
•
Lowers system costs by eliminating PCB layers required for
RGMII, SGMII, and SerDes MAC interface options
Copper or SerDes line interface options
•
•
•
routing high-density solutions.
Reduced I/O pin requirements with RGMII (over 50%), SGMII
(over 75%), and SerDes (over 80%).
Clock timing can be adjusted to eliminate board trace delays
required by the RGMII specification.
Lowers MAC/switch costs by reducing the number of pins
required to interface with the PHY.
Fully compliant with IEEE 802.3, IEEE 802.3u, and
IEEE 802.3ab standards
0.13-micron CMOS—low power and cost
•
•
Low power
•
•
750 mW per port
Advanced power management
Flexibility for copper or fiber applications.
•
•
Provides compatibility with IEEE standard devices operating
at 10, 100, and 1000 Mbps at half-duplex and full-duplex.
Trace matched output impedance
Line-side loopback
•
•
•
•
Eases system level debug.
•
•
Low EMI emissions
Enables use of low-cost magnetics, even in high-density (48+)
designs.
Cable plant diagnostics
•
•
•
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.
Cable diagnostic function characterizes cable plant condition
and immediately indicates cabling issues.
•
•
Over 3kV of CESD tolerance prevents equipment damage and
return.
•
Prevents erroneous equipment return due to bad cable plants
Prevents manufacturing fallout due to bad cable plants
•
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
•
•
•
•
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.
