±15kV ESD Protected MII/RMII Fast-Ethernet PHY with HP Auto-MDIX & SMSC flexPWR™ in a Small Footprint
- click image to enlarge
The SMSC LAN8700 is a low-power, variable I/O voltage, analog interface IC with HP Auto-MDIX for high-performance embedded Ethernet applications.
The LAN8700 can be configured to operate on a single 3.3V supply utilizing an integrated 3.3V to 1.8V linear regulator.
The LAN8700 consists of an encoder/decoder, scrambler/descrambler, wave-shaping transmitter, output driver, twisted-pair receiver with adaptive equalizer and baseline wander (BLW) correction, and clock and data recovery functions.
The LAN8700 can be configured to support either the Media Independent Interface (MII) or the Reduced Media Independent Interface (RMII).
It contains a full-duplex 10-BASE-T/100BASE-TX transceiver and supports 10-Mbps (10BASE-T) operation on Category 3 and Category 5 unshielded twisted-pair cable, and 100-Mbps (100BASE-TX) operation on Category 5 unshielded twisted-pair cable.
