A P P L I C AT I O N S :
8-port unmanaged Gigabit Ethernet SMB/SOHO switch
8-port Web-managed Gigabit Ethernet SMB/SOHO switch
BENEFITS:
Ensures maximum data throughput in highly loaded networks
Reduces the need for any PHY components thereby significantly
reducing overall systems cost
Eliminates the need for external buffer memory while maintaining high
peak load performance
Enables advanced switch management, using run-time protocols, and
low cost unmanaged/Web-managed operation
Enables LAN edge products to generate standard priority that can be
used in the core network
Connects effortlessly to networks, hosts, and controllers that use up to
9.6-kilobyte frames
Optimizes network performance to support any digital stream, from
internet browsing to VoIP and video
Stores a large amount of stations at wire-speed in the on-chip MAC
Table, ensuring optimal network performance and scalability
Provides high bandwidth uplinking abilities
Ensures lossless data transmission while supporting existing legacy
Ethernet equipment
Eliminates unwanted flooding of ports, and thereby increases overall
network performance
Supports complex network topologies with fast failure recovery and
access control
Reduces CPU overhead and enables the CPU to allocate additional
cycles for protocol processing
Enables real-time cable diagnostics and low cost magnetics
