Description
The KSZ8841P is a single chip Fast Ethernet MAC con-
troller with a 32 bit/33MHz PCI processor interface. The
KSZ8841P is fully compliant with the IEEE 802.3u stan-
dard. It will also be available in an Industrial Temperature
part, the KSZ8841-PMQLI from Q1 2006.
Physical signal transmission and reception are enhanced
through the use of analog circuitry that makes the design
more efficient and allows for lower power consumption
and smaller chip die size. The KSZ8841P is designed
with a low-power CMOS design and a high-performance
process that uses a single 3.3V power supply with 5V
tolerant I/O.
The KSZ8841P is a mixed signal analog/digital device of-
fering wake-on-LAN technology. Its extensive feature set
includes management information base (MIB) counters
and CPU control/data interfaces to effectively address both
current and emerging Fast Ethernet applications.
