silicon integration highest levelbridged repeater achieved five-port 10/100 AC206 integrates:
Five transceivers 10BASE-T/100BASE-TX uplink port repeater 100M repeater Two-port bridge including: memory address table packet buffer Local address filter Address table entries
member AC206 architecture AC208 product family, with same fabrication technology. Other members product family include AC208, AC207, AC205 AC205i. Provides easy product migration. Provides seamless integration connections system expansion. Includes lowest overall cost form factor 10/100 repeater design SOHO gateway router design. Field-proven, industry-standard 10BASE-T/ 100BASE-TX Fast Ethernet transceivers lower overall system interoperability reliability risks. Integrated memory reduces component cost manufacturing testing costs. power consumption heat dissipation allow high design density system cost. EEPROM-configured system parameter enables costsensitive architecture. Configurable reversed 7-wire interface allow versatile application with connectivity.

Altima AC206 highly integrated 0.25u CMOS silicon solution. combines functions 10/100 dual-speed bridged repeater, including transceivers, reversed 7-wire hard-wire configurable interface, internal repeaters, repeater backplane busses expansion, two-port bridge with embedded memory. AC206 contains five 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, reversed 7-wire compatible interface allows AC206 designed into many different applications, reducing number separate devices necessary meet multiple design requirements. AC206 represents marked improvement over previous generation dual-speed bridged repeater family AC108R. Because memory embedded silicon, AC206 offers obvious advantage cost savings discrete memory device. Additionally, 128-pin PQFP package means savings manufacturing testing.
Because AC206 smallest footprint lowest power consumption, per-port basis, micro-LAN solution, when system costs considered power, heat, components real estate AC206 provides lowest overall system cost most reliable design. AC206 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
