5-PORT ULTRA LOW POWER 10/100 ETHERNET BRIDGED REPEATER
AC205 FEATURES
• The highest level of silicon integration achieved for a
five-port 10/100 bridged repeater
• The AC205 integrates:
• Five transceivers of 10BASE-T/100BASE-TX
• 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 7-wire port}
• ^{Fully compliant auto-negotiation}
• ^{Very small package – 100-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}
SUMMARY OF BENEFITS
• AC205 is a member of the AC208 product family, with
the same architecture and fabrication technology.
Other members in the product family include AC208,
AC207, AC206 and AC205i.
• ^{Provides easy product migration.}
• ^{Provides seamless integration for WAN connections}
and system expansion.
• Provides lowest overall cost and form factor for 10/100
repeater hub design and SOHO gateway and router
design.
• Utilizes field-proven, industry-standard 10BASE-T/
100BASE-TX Fast Ethernet transceivers to 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 cost-
sensitive architecture.
• Configurable MII or 7-wire interface allows versatile
application with WAN connectivity.
