    8-Port 10/100 Ethernet Switch

     

    产品信息

    The KS8997 contains eight 10/100 physical layer transceivers, eight MAC (Media Access Control) units with an integrated layer 2 switch. The device runs as an eight port integrated switch.

    The KS8997 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 KS8997 supports 10BaseT and 100BaseTX through auto-negotiation 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.
