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.
Parametrics
AC205KQM absolute maximum ratings: (1)Supply Voltage: 2.7 V ~ 5.5 V; (2)Operating Temperature: -40℃ ~ 85℃.
Features
