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. FEATURES ■ Complete physical interface solution ■ Conforms to IEEE 802.3i–1990 (10Base-T) ■ On-chip transmit and receive filters ■ Automatic AUI/Twisted Pair selection (ML2652 only) ■ Power down mode ■ Pin selectable controller interface-(CS0 – CS2) Intel 82586, 82596 NSC DP8390 Seeq 8003, 8005 AMD 7990 ■ Automatic polarity correction ■ Pin selectable receive squelch levels ■ Status pins for: link detect, receive & transmit activity, collision, jabber, AUI selection ■ Single supply 5V ±5%
