IP1717LF

Product Summary

The IP1717LF is a 18-port 10/100Mbps Smart Switch Controller. Supporting 16-port SS-SMII, 2-port MII andvarious advanced features, the fitsboththe office switch and the ETTH( Ethernet to theHome) application. The IP1717LF embedsinternal SSRAM for the use of the packet bufferand the MAC address table. Besides thetraditional switch functions, the device provides the easy-to-design solution, fitting therequirement of most switch application. The IP1717LF also supports some features whichcan simplify the customer’s design from theviewpoint of the system.
