The MxL86111 is a state-of-the-art single port Ethernet Gigabit Copper PHYs with low power consumption, a small footprint and low RBOM. It supports 10BASE-Te, 100BASE-TX and 1000BASE-T on the twisted pair interface. 10BASE-Te and 100BASE-TX support half- and full-duplex and 1000BASE-T full-duplex mode of operation. It is available in both commercial and industrial temperature ranges.

MxL86111 integrates an SGMII / 100BASE-FX / 1000BASE-X interface and supports RGMII or SGMII as the MAC interface and dual media, media converter or RGMII to
SGMII bridge applications.

The MxL86111 has a low power consumption and supports Energy Efficient Ethernet (EEE) for 100BASE-TX and 1000BASE-T. Further power saving can be achieved using the Wake-on-LAN functionality and the no-link detection.

The device is available in a small 6x6 QFN48 package and can be operated from a single 3.3V power supply using the integrated DC/DC converter with few external components.
Advanced applications are supported by the industrial temperature range variant (MxL86111I), SyncE support, integrated SerDes, and the integrated SGMII/BASE-X interface.
