ASIX AX88783LF

Product Info

This product is EOL. Once inventory is sold, no further inventory will be recieved.

The AX88783 is a 2-port Ethernet switch featuring a third port, 8/16/32-bit Non-PCI/SRAM-like host interface. The built-in switching fabric supports non-blocking wire-speed forwarding and offers an advanced switch feature set that includes tag/port-based VLAN, spanning tree, QoS priority management, rate control, port security, port mirroring, IGMP snooping, and MIB counters. ASIX's new ICs are targeted at performance-sensitive embedded applications that need to support two Ethernet ports, typically one for a LAN port and one for a WAN port. Also, the AX88783 support HP Auto-MDIX, which allows both the straight-through and crossover cables to be directly connected to the device without end user's guesswork.

As the multimedia applications for distributing voice, video, and data remotely over the network grow, demands for adding Ethernet connectivity to an embedded system have also been increasing. Because of its ease of use, low-cost, high-throughput, and seamlessly interoperating with existing computer network, the Ethernet is a very attractive infrastructure technology to expand beyond the SOHO networking and Enterprise space. There is a growing awareness of the need for a network in the home that can easily distribute and share the high quality digital video and audio content among different home devices. Ethernet is also expanding into industrial applications on the factory floor. ASIX's latest chip offerings can meet our customer's needs for current and emerging 2-port Ethernet applications, such as VoIP phone/ATA adapters, IP cameras, next-generation IP-STB/IPTV, industrial controller/network sensors, port redundancy/port monitoring, and Single Board Computers (SBC).

To help customers evaluate and develop applications with the AX88783, ASIX provides comprehensive technical support including hardware and software application notes, user guides, schematics, PCB layout guides, and drivers for Linux/WinCE operating systems.
