PHY 1-CH 10Mbps/100Mbps 64-Pin TQFP

The SMSC LAN8187I is a low-power, industrial temperature (LAN8187i), variable I/O voltage, analog interface IC with HP Auto-MDIX for high-performance embedded Ethernet applications. The LAN8187 can be configured to operate on a single 3.3V supply utilizing an integrated 3.3V to 1.8V linear regulator. An option is available to disable the linear regulator to optimize system designs that have a 1.8V power plane available.
