AC206 OVERVIEW
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.

AC206 FEATURES
• The highest level of silicon integration achieved for a five-port 10/100 bridged repeater
• 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
• 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
• Very low power – typical < 1.2W
   • Selectable TX drivers for 1:1 or 1.25:1 transformers to enable additional power reduction
• Cable detect mode – typical < .20W
• Power down mode – typical < .05W
