ASIX Electronics Corp. announced the AX88742 and AX88783, two new Ethernet IC solutions. The 2-port Ethernet devices can be configured as a fully managed, Layer-2 switch with the third port being connected to any host processor. Using AX88742 with 32-bit PCI microcontroller or AX88783 with generic 8/16/32-bit microcontroller, designers can provide 2-port Ethernet connectivity to the embedded systems to distribute voice, video, and data remotely over the network.
The AX88783 is a 2-port Ethernet switch featuring a third port, 32-bit Non-PCI/SRAM-like host interface. The AX88742 is a 2-port Ethernet switch with the third port being connected to a 32-bit/33MHz PCI 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 AX88742/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.
Limited samples of the AX88742 and AX88783 are available now, and volume production is scheduled in the second quarter of 2008. The chips are offered in RoHS compliant version.
