KS8997

8-Port 10/100 Integrated Switch with PHY and Frame Buffer

Micrel 

General Description

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.

Rev 1.1

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.
