ML6694

May 1997 ML6694* 100BASE-TX Physical Layer with 5-Bit Interface GENERAL DESCRIPTION The ML6694 is a high-speed physical layer transceiver that provides a 5-bit (or symbol) interface to unshielded twisted pair cable media. The ML6694 is well suited for repeater applications using repeater controllers with the 5-bit interface. The ML6694 may also be used in FDDIover-copper applications. The ML6694 integrates 125MHz clock recovery/ generation, receive adaptive equalization, baseline wander correction and MLT-3/10BASE-T transmitter.
