GENERAL DESCRIPTION

The ML4658 10BASE-T Transceiver is a single chip cable line driver/receiver that provides all of the functionality required to implement both an internal and external IEEE 802.3 10BASE-T MAU. This part offers a standard IEEE 802.3 AU interface that allows it to directly connect to industry standard manchester encoder/decoder chips or to an AUI cable.
