GENERAL DESCRIPTION

The ML2652, 10BASE-T Physical Interface Chip, is a complete physical interface for twisted pair and AUI Ethernet applications. It combines a 10BASE-T MAU, Manchester Encoder/Decoder, and Twisted Pair Interface filters in one monolithic IC. A complete DTE interface for twisted pair Ethernet can be implemented by combining the ML2652, an Ethernet controller, and transformers.
