AC206 OVERVIEW

The Altima AC206 is a highly integrated 0.25u CMOS silicon solution. It combines all the functions of a 10/100 dual-speed bridged repeater, including PHY transceivers, an MII or reversed MII or 7-wire hard-wire configurable interface, two internal repeaters, two repeater backplane busses for expansion, and a two-port bridge with 32 KB embedded memory.
