Altima AC207 highly integrated 0.25u CMOS silicon solution. combines functions 10/100 dual speed bridged repeater including transceivers, 7-wire hard-wire configurable interface, internal repeaters, twoport bridge with embedded memory. AC207 contains eight 10BASE-T/100BASE-TX Fast Ethernet transceivers, which configured into fullduplex uplink port. transceivers perform physical layer interface functions 10BASE-T Ethernet Category unshielded twisted pair (UTP) cable 100BASE-TX Fast Ethernet Category cable. MII-compatible interface allows AC207 designed into many different applications, reducing number separate devices necessary meet multiple design requirements. AC207 represents marked improvement over previous generation dual-speed bridged repeater family AC108R. Because memory embedded silicon, AC207 offers obvious advantage cost savings discrete memory device. Additionally, 128-pin PQFP package means savings manufacturing testing.
Because AC207 smallest footprint lowest power consumption, per-port basis, micro-LAN solution, when system costs considered power, heat, components real estate AC207 provides lowest overall system cost most reliable design. AC207 member AC208 product family. AC208 product family includes AC208, AC207, AC206, AC205 AC205i with following features configurations: AC208: 128-pin PQFP, eight-port with cascadable backplane AC207: 128-pin PQFP, eight-port with 7-wire AC206: 128-pin PQFP, five-port with reversed 7-wire, cascadable repeater backplane AC205: 100-pin PQFP, five-port with 7-wire AC205i: 100-pin PQFP, five-port with 7-wire single independent port phone
