PRODUCT
Brief
5-PORT ULTRA LOW POWER 10 / 100 ETHERNET BRIDGED REPEATER
of silicon integration · The highest levelbridged repeater achieved for a five-port 10 / 100 · The AC206 integrates:
· Five 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 · AC206 is architecture and AC208 product family, with the same fabrication technology. Other members in the product family include AC208, AC207, 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 / 100BASE-TX 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 allow high design density and low system cost. EEPROM-configured system parameter enables costsensitive architecture. Configurable MII or reversed MII or 7-wire interface allow versatile application with WAN connectivity.
· MII or reversed MII or 7-wire port · Cascade to 13, 21, and 29 port configuration · Fully compliant auto-negotiation · Very small package - 128-pin PQFP
· 280 sq. mm footprint
· Selectable TX drivers for 1:1 or 1.25:1 transformers to enable additional power reduction

The Altima AC206 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 reversed MII or 7-wire hard-wire configurable interface, two internal repeaters, two repeater backplane busses for expansion, and a two-port bridge with 32 KB embedded memory. The AC206 contains five 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, reversed MII and 7-wire compatible MAC interface allows the AC206 to be designed into many different applications, reducing the number of separate devices necessary to meet multiple design requirements. The AC206 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 AC206 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 AC206 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 AC206 provides the lowest overall system cost and most reliable design. The AC206 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
