LAN8700IC-AEZG-TR Product Details

The Microchip LAN8700/LAN8700i is a low-power industrial temperature (LAN8700i), variable I/O voltage, analog interface IC with HP Auto-MDIX support for high-performance embedded Ethernet applications. The LAN8700/LAN8700i 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.

The LAN8700/LAN8700i 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/LAN8700i can be configured to support either the Media Independent Interface (MII) or the Reduced Media Independent Interface (RMII).

The LAN8700/LAN8700i is compliant with IEEE 802.3-2005 standards (MII Pins tolerant to 3.6V) and supports both IEEE 802.3-2005 compliant and vendor-specific register functions. 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.

*The LANCheck online design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.



    Note: The LAN8700/LAN8700i are not recommended for new designs. The LAN8710/LAN8720 are the suggested replacement devices for these products.
