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, a twoport bridge with 32 KB embedded memory. The AC207 contains eight 10BASE-T/100BASE-TX Fast Ethernet transceivers, one of which can be configured into a fullduplex uplink port. The transceivers perform 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-compatible MAC interface allows the AC207 to be designed into many different applications, reducing the number of separate devices necessary to meet multiple design requirements. The AC207 represents a marked improvement over the previous generation of the dual-speed bridged repeater family AC108R. Because the memory is embedded in the silicon, the AC207 offers the obvious advantage of cost savings in the discrete memory device. Additionally, a 128-pin PQFP package means savings in manufacturing and testing. solution, when all system costs are considered — power, heat, components and real estate — the AC207 provides the lowest overall system cost and most reliable design. The AC207 is a member of the AC208 product family. The AC208 product family includes the AC208, AC207, AC206, AC205 and AC205i with the following features and configurations: • AC208: 128-pin PQFP, eight-port TX with cascadable backplane • AC207: 128-pin PQFP, eight-port TX with MII or 7-wire • AC206: 128-pin PQFP, five-port TX with MII or reversed MII or 7-wire, cascadable repeater backplane • AC205: 100-pin PQFP, five-port TX with MII or 7-wire • AC205i: 100-pin PQFP, five-port TX with MII or 7-wire and single independent TX port for IP phone Because the AC207 has the smallest footprint and the lowest power consumption, on a per-port basis, of any micro-LAN © 2002 by ALTIMA COMMUNICATIONS, INC.
