Microchip | KSZ8997

The KSZ8997 is a 8 Port 10/100 Switch with PHY & Frame Buffers and it is available in 128-Pin PQFP package .It contains eight 10/100 physical layer transceivers, eight MAC (Media Access Control) units with an integrated layer 2 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.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.
