Additional Details

The RTL8213-GR operates with a 3.3V power supply. The integrated digital adaptive equalizers compensate for signal attenuation and distortion, ensuring reliable data transmission over standard Cat 5e cables up to 100 meters. It supports various MAC interfaces, including GMII (Gigabit Media Independent Interface), RGMII (Reduced Gigabit Media Independent Interface), and MII (Media Independent Interface), providing flexibility in connecting to different MAC controllers. The GR likely indicates a specific package type or revision. It also incorporates power-saving features to reduce power consumption during idle periods. The Wake-on-LAN functionality allows the device to be powered on remotely over the network.
