GENERAL DESCRIPTION

The MTD392 family includes a series of products, MTD392/3/4 and MTD492/3/4. The MTD392 product family is built for easy MAU interface in a coaxial Ethernet network. The MTD392 product family integrates the coaxial cable interface functions of Medium Attachment Unit (MAU) in Ethernet or Cheapernet LAN applications. In an Ethernet 10Base5 network, the MTD392 product family is mounted on the thick Ethernet coaxial cable and connects to a station through an AUI cable.
