Product Summary

The Altima AC205KQM 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 7-wire hard-wire configurable interface, two internal repeaters, and a two-port bridge with 32 KB embedded memory. The AC205KQM contains five 10BASE-T/100BASE-TX Fast Ethernet transceivers, one of which can be configured into a fullduplex uplink port. The transceiver of the AC205KQM performs all of the physical layer interface functions for 10BASE-T Ethernet on Category 3, 4, or 5 unshielded twisted pair (UTP) cable and 100BASE-TX Fast Ethernet on Category 5 UTP cable. The MII and 7-wire compatible MAC interface allows the AC205KQM to be designed into many different applications, reducing the number of separate devices necessary to meet multiple design requirements.
