Provides with IEEE standard devices • operationcompatibility at 10, 100, and 1000 Mbps at half- and full- • • • • • Cable plant analyzer function detects cable plant impairments • Link quality indication LED • Automatic detection and correction of wiring pair swaps, pair skew, and pair polarity • Automatic MDI/MDIX crossover at all speeds B E N E F I T S duplex. Requires no airflow or heatsink. 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 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. High-density options: • Lowers systempackage costs. • • Simplifies system and board design. • RGMII/RTBI reduces I/O pin requirement over GMII and TBI by more than 50%.
