SUMMARY OF BENEFITS
⢠Provides interoperability with IEEE standard devices
operating at 10, 100, and 1000 Mbps at half- and full-
duplex.
⢠Lowers system cost and reduces solution footprint.
⢠Requires no airflow or heatsink.
⢠Provides compliance with PCI 2.2 and PC99/PC2000.
⢠Reduces system design constraints to meet EMI
emissions standards.
⢠Automatically configures the link to support the
highest possible speed based on link partner capability
and characteristics of the channel.
⢠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.
⢠Simplifies system and board design.
⢠RGMII/RTBI reduces I/O pin requirement over GMII and TBI
by more than 50%.
