AC205 Application with AC208 System Block Diagram
•
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.
