GENERAL DESCRIPTION
MTD214 contains integrated functions of the Ethernet encoder/decoder and UTP/AUI interface. The
encoder/decoder conforms to IEEE 802.3 protocol and performance requirements while also retaining
compatibility with most popular network controllers. The UTP transceiver has a built-in waveform shaping
function thus eliminating the requirement of an external filter. The transceiver also contains the functions of
automatic media selection and polarity correction. MTD214 is available in 28-pin plastic DIP (600mil) or SOJ
(300mil) packages.
