AC207 System Block Diagram
•
AC207 is a member of the AC208 product family with
the same architecture and fabrication technology.
Other members in the product family include AC208,
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 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
allows 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.
