SUMMARY OF BENEFITS

• 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 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 

• Ease of manufacturing with JTAG support, simplified power supply, and multiple MAC interfaces
