Product Description

The KSZ8999 is an integrated 9-port 10/100 Switch with PHY and frame buffer. It contains eight 10/100 physical layer transceivers, nine MAC (Media Access Control) 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 an MII (media independent interface). 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 KS8999 is designed to reside in an unmanaged design not requiring processor intervention. This is achieved through I/O strapping or EEPROM programming at system reset time. On the media side, the KS8999 supports 10BaseT, 100BaseTX and 100BaseFX as specified by the IEEE 802.3 committee.
