1 Introduction
The SMSC LAN8700 is a low-power, variable I/O voltage, analog interface IC with HP Auto-MDIX
support for high-performance embedded Ethernet applications. 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 EVB8700 is an Evaluation Board (EVB) that interfaces a standard 40-pin female MII connector
from an existing MAC controller to the SMSC LAN8700 Ethernet PHY, and out to an RJ45 Ethernet
Jack for 10/100 connectivity.
A simplified block diagram of the EVB8700 can be seen in
