Network Interface and Power Overview Function and interface: Female RJ45 jack with Auto MDIX support for automatic correct wiring, reducing the need to match port types or use crossover cables. Enables seamless connections to switches, routers, and hosts. Performance indicator: LED indicator shows Link at 1000Mbps, providing a clear, ataglance status of gigabit connectivity. Power and integration: Integrated onchip 3.3V to 2.5V regulator, requiring only a single 3.3V power supply. Simplifies the power design and reduces external components. Compatibility and reliability: Designed for standard 1 Gigabit Ethernet environments with auto negotiation features to ensure reliable performance across devices. Applicationfriendly design: Suitable for integration into networking hardware, embedded systems, development boards, or network appliances that require a robust 1G Ethernet interface with simple power requirements. Use scenarios Embedded development and prototyping: Attach to a development board or custom hardware to enable reliable 1G network testing without needing additional crossover cables or adapters. Office or home lab expansion: Add a gigabit Ethernet port to a switch, router, NAS, or workstation to expand connectivity with straightforward power needs and clear link status. Network appliance or evaluation setup: Integrate into a small network appliance or evaluation rig that requires a gigabit interface with a simple singlesupply 3.3V power design.
