www.DataSheet4U.com MYSON TECHNOLOGY MTD907 Ethernet Encoder/decoder and 10BaseT Transceiver with Built-in Waveform Shaper FEATURES Pin-out and functionally compatible with Level One LXT907. Built-in UTP waveform shaping function - no external filters required. Integrated Manchester encoder/decoder. 10Base-T compliant transceiver and AUI transceiver. Full duplex capability. Automatic and manual interface selection (AUI/TP). Automatic TP polarity detection and correction. Heartbeat enable/disable function and jabber disable function. Drives 4 LED status indicators. 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.
