The AX88613 is a single-chip 3-port 10/100M Ethernet Switch controllers featuring a 3-port switching fabric with QoS priority management, three 10/100M MACs, two 10/100M PHYs, and MII host interface. The built-in switching fabric in the AX88613 supports non-blocking wire-speed forwarding and offers an advanced switch feature set that includes tag/port-based VLAN, spanning tree, rate control, port security, port mirroring, IGMP snooping, MIB counters and four priority queues for QoS functions including Port-Based, 802.1p VLAN, IPv4 TOS and IPv6 COS to prioritize voice, video, audio and data traffic delivery.
The AX88613 have integrated a voltage regulator and provide support for programmable I/O voltage options of 3.3V/2.5V/1.8V to enable a highly optimized system design. As semiconductor designs migrate to advanced process geometries like 90nm, 65nm, 45nm and beyond, many of today's higher performance ASICs, SoCs and FPGAs require lower I/O voltages.
The AX88613 combine the benefits of high integration and small form factor making them ideal single-chip solutions for designing high performance, QoS-aware and cost effective 2-port Ethernet functions for embedded system applications such as VoIP phone/ATA adapters, surveillance IP cameras, next-generation IP-STB/IPTV, industrial controller/network sensors, port redundancy/port monitoring and Single Board Computers (SBC).
