KSZ8997

The KSZ8997 is a 8-port 10/100 Integrated Switch with PHY and frame buffer. 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 and smaller chip die size.
