Overview
May 1997 ML6698* 100BASE-TX Physical Layer with 5-Bit Interface GENERAL DESCRIPTION The ML6698 is a high-speed physical layer transceiver that provides a 5-bit (or symbol) interface to unshielded twisted pair cable media.
The ML6698 is well suited for adapter card applications using the DEC 21143, the Macronix MX98713, or equivalent Media Access Controllers (MACs).
The ML6698 may be used in other 100BASE-TX applications requiring the 5-bit interface as well as FDDI-over-copper applications.
The ML6698 integrates 125MHz clock recovery/ generation, receive adaptive equalization, baseline wander correction and MLT-3/10BASE-T transmitter.
FEATURES s s s s s s s s 5-bit (or symbol) parallel interface Compliant to IEEE 802.
