SUMMARY OF BENEFITS
Simplifies system and board design.
-
Reduced I/O pin requirements with RGMII (over 50%).
-
On-chip RGMII timing delay
Provides interoperability with IEEE standard devices
operating at 10 Mbps, 100 Mbps, and 1000 Mbps at half- and
full-duplex.
Lowers system bill of materials (BOM) cost and simplifies
system design.
Requires no airflow or heatsink.
Eases system level debug.
Reduces system design constraints to meet EMI emissions
standards.
Cable diagnostic function characterizes cable plant condition
and immediately indicates cabling issues.
-
Prevents erroneous equipment return due to bad cable
plants.
-
Prevents manufacturing fall-out due to bad cable plants.
High 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.
