Compact solution for high density uplink applications, enabling
10/100/1000BASE-T and 1000BASE-X/100BASE-FX uplinks
1000BASE-X and 100BASE-FX support from same line side pins
enables direct interface to SFP modules
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
Eases system level debugging
Enables use of low-cost magnetics
Cable diagnostic function characterizes cable plant condition
and immediately indicates cabling issues.
• Prevents erroneous equipment return due to bad cable plants
• Prevents manufacturing fallout due to bad cable plants
• Allows immediate uptime at reduced speeds (100BASE-TX or
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
Ease of manufacturing with JTAG support, simplified power
