The ADM6993/X is a single chip integrating two 10/100 Mbps MDIX TX/FX transceivers, a three-port 10/100M Ethernet L2 switch controller, and features converter mode to meet demanding applications, including Fiber-to-Ethernet media converters, 2/3 port Ethernet switches, VoIP gateways, and NAT routers. The ADM6993X is the environmentally friendly “green” package version.
The ADM6993/X supports priority features on Port-Base priority, VLAN TAG priority and IP TOS precedence checking at individual ports. This is done through a small low-cost micro controller to initialize or on-the-fly to configure. The priority of packets can be tagged based on TCP port number for the multi-media application.
Feature List:
* 3-port10/100M switch integrated with a 2-port PHY (10/100TX and 100FX ) and 3rd MAC port as GPSI/MII/RMII/HDLC
