The LAN8700C-AEZG is a low-power variable I/O voltage Analogue Interface IC with HP auto-MDIX support for high-performance embedded Ethernet applications. The LAN8700C-AEZG can be configured to operate on a single 3.3V supply utilizing an integrated 3.3 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. The LAN8700C-AEZG 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 LAN8700C-AEZG can be configured to support either the media independent interface (MII) or the reduced media independent interface (RMII). The LAN8700C-AEZG 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.
