Four fully integrated 10BASE-T/100BASE-TX/
1000BASE-T Gigabit Ethernet transceivers
RGMII and RTBI interface options
Low power quad-port integration enables single-row,
high port density switches.
•
•
Lowers system costs by eliminating PCB layers required for
routing high density solutions
•
•
•
•
Fully compliant with IEEE 802.3, 802.3u, and 802.3ab
•
Clock timing can be adjusted to eliminate board trace delays
required by the RGMII specification.

Ethernet@WireSpeedTM logic automatically selects the
maximum speed based on channel conditions
Reduces design constraints in high-density
applications that have higher EMI emissions.
Automatically configures the link to support the
highest possible speed based on link partner capability
and characteristics of the channel.
Cable plant diagnostic
Cable plant analyzer function detects cable plant impairments

Cable diagnostic function characterizes cable plant
condition and immediately indicates cabling issues.
Automatic detection and correction of wiring pair swaps, pair
skew, and pair polarity
Prevents erroneous equipment return due to bad cable plants.
Prevents manufacturing fall-out due to bad cable plants.
