    KS8999
    Integrated 9-Port 10/100 Switch with
    PHY and Frame Buffer
    Rev 1.14 General Description
    The KS8999 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 a 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.
    Physical signal transmission and reception are
    enhanced through use of analog circuitry that makes the
    design more efficient and allows for lower power
    consumption and smaller chip die size. ...
