Product Description
The AX88658A is an 8-port 10/100/1000 Mbps Ethernet switch with, GMII/RGMII or MII Interface. The switch
controller provides network system manufacturers the ideal platform for building smart and cost-effective backbone
switches for small to medium sized businesses.
The AX88658A 8-port 10/100/100 BASE-T single chip switch controllers combine the benefits of network
simplicity, flexibility and high integration. Its highly integrated feature set enables network system manufacturers to
build smart switches for the fast-growing small to medium business market segment.
Benefits of AX88658A Switches are below.
Simplicity
Provides a smart, simple and low maintenance plug-and-play network interconnect system for small to
medium size businesses
Flexibility
Highly scalable configuration allows system manufacturers to enable or disable a range of features to best
meet their target price point.
Integration
Highly integrated design drives down overall switch manufacturing costs.
Target Applications
8-port Gigabit Layer 2 Switches for workgroup
High-port count Layer 2 switches with trunking
High performance solution of Ethernet backbone
