BENEFITS
8-PORT ULTRA LOW POWER 10/100 ETHERNET BRIDGED REPEATER
integration * The highest level of siliconrepeater achieved for an eight-port 10/100 bridged * The AC207 integrates:
* Eight transceivers of 10BASE-T/100BASE-TX * One uplink port * 10M repeater * 100M repeater * Two-port bridge including: - 32 KB memory for address table and packet buffer - Local MAC address filter - Address table up to 1K entries
a member of the * AC207 is architecture and AC208 product family with the same fabrication technology.
* * * * * * * *
* MII or 7-wire port * Fully compliant auto-negotiation * Very small package - 128-pin PQFP * Very low power - typical < 1.8W
* 280 sq. mm footprint
* Cable detect mode - typical < .32W * Power down mode - typical < .08W
* Selectable TX drivers for 1:1 or 1.25:1 transformers to enable additional power reduction
Other members in the product family include AC208, AC206, AC205 and AC205i. Provides easy product migration. Provides seamless integration for WAN connections and system expansion. Includes lowest overall cost and form factor for 10/100 repeater hub design and SOHO gateway and router design. Field-proven, industry-standard 10BASE-T/100BASETX Fast Ethernet transceivers lower overall system interoperability and reliability risks. Integrated memory reduces component cost and manufacturing and testing costs. Low power consumption and low heat dissipation allows high design density and low system cost. EEPROM-configured system parameter enables costsensitive architecture. Configurable MII or 7-wire interface allows versatile application with WAN connectivity.

The Altima AC207 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, 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. Because the AC207 has the smallest footprint and the lowest power consumption, on a per-port basis, of any micro-LAN
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
