KS8995

The KS8995 contains five 10/100 physical layer transceivers, five MAC (Media Access Control) units with an integrated layer 2 switch. The device runs in two modes. The first mode of KS8995 is a five port integrated switch and the second is as a five port switch with th e fifth port decoupled from the physical port. In this mode access to the fifth MAC is provided using a MII (Media Independent Interface).

Useful configurations include a stand alone five port switch as well as a four port switch with a routing element connected to the extra MII port. The additional port is also useful for public network design not requiring processor intervention. This is achieved through I/O strapping at system reset time On the media side, the KS8995 supports 10BaseT, 100BaeTX and 100BaseFX as specified by the IEEE 802.3 committee.

Physical signal transmission and reception are enhanced through use of analog circuitry that makes the design of KS8995 more efficient and allows for lower power consumption and smaller chip die size.
