AC208 with AC206 System Block Diagram
•
AC208 is the first chip of the AC208 product family
with the same architecture and fabrication technology.
Other members of the product family include AC207,
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 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
allows high design density and low system cost.
•
EEPROM-configured system parameter enables cost-
sensitive architecture.
•
Repeater backplane compatibility with AC108R
enables flexibility and expandability in system
architecture.
SUMMARY OF BENEFITS
8-PORT ULTRA LOW POWER 10/100 ETHERNET BRIDGED REPEATER
PRODUCTPRODUCT
BriefBrief
AC208
•
The highest level of silicon integration achieved for an
eight-port 10/100 bridged repeater
•
The AC208 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
•
Cascadable to 16, 24, and 32 port configuration
•
Fully compliant auto-negotiation
•
Very small package – 128-pin PQFP
• 280 sq. mm footprint
•
Very low power – typical < 1.8W
• Selectable TX drivers for 1:1 or 1.25:1 transformers to enable
additional power reduction
•
Cable detect mode – typical < .32W
•
Power down mode – typical < .08W
