IP1717 16+1 ports Ethernet Switch Controller with Octal-PHYs
 

General Description :

The IP1717 is a cost effective and fully integrated single chip. It integrates a 17-port switch controller, an octal PHY transceiver and SSRAM. Each of PHY transceiver complies with 802.3u specification and HP-license Auto MDI/MDIX.                               

The IP1717 also provides a 3S-MII interface to connect an octal PHY for a 16-port dumb switch application and a MII interface for a smart/management switch application.

In addition, it supports full smart switch functions, including IGMP snooping, 4 priority queues, TOS, TCP/UDP port number priority, 802.1Q VLAN, port security, protocol filter/forwarding and bandwidth control.
