GENERAL DESCRIPTION
MTD907 is an integrated Ethernet Endec and 10Base-T transceiver with built-in UTP transmission waveform
shaping function. The integrated encoder/decoder conforms to IEEE802.3 standards and provides all needed
active circuitry with which to interface the majority of IEEE802.3-conforming controllers to either the 10Base-T
media or attachment unit interface (AUI). The functions provided by MTD907 include Manchester
encoding/decoding, jabber detection, automatic media selection, reception squelch and transmission
waveform shaping, automatic UTP polarity detection and correction for the UTP media.
