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.
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.
