Reduces design constraints in high-density • applications that have higher EMI emissions. Automatically the link to support the • highest possibleconfigures speed based on link partner capability • 1W per port • Advanced power management TM • 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 • • Robust CESD tolerance • Support for jumbo packets up to 9 KB • IEEE 1149.1 (JTAG) boundary scan • Lowers system costs by eliminating PCB layers required for routing high density solutions • SGMII interface reduces I/O pin requirement over RGMII by more than 50%. • Lowers MAC/switch costs by reducing the number of pins required to interface to the PHY. Provides compatibility with IEEE standard devices • operating at 10, 100, and 1000 Mbps at half- and fullduplex. 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.
