KSZ8999I

KSZ8999I is an integrated 9-port 10/100 switch with PHY and frame buffer. It contains eight 10/100 physical layer transceivers, nine Media Access Control (MAC) units with an integrated layer 2 switch. The device runs in two modes. The first mode is an eight-port integrated switch and the second is as a nine-port switch with the ninth port available through a Media Independent Interface (MII). Useful configurations include a stand alone eight-port switch as well as an eight-port switch with a routing element connected to the extra MII port. The additional port is also useful for a public network interfacing. The KSZ8999 is designed to reside in an unmanaged design that does not require processor intervention. This is achieved through I/O strapping or EEPROM programming at system reset time.
