KS8001Product Brief
LinkMD is a trademark of Micrel, Inc.
The KS8001 is a 10BASE-T,100BASE-TX, and 100BASE-
FX Physical Layer Transceiver, which provides MII/RMII/
SMII interfaces to MACs and switches. Utilizing a unique
mixed-signal design that extends signaling distance while
reducing power consumption, the KS8001 represents
Micrel’s fth generation single-port Fast Ethernet PHY.
Micrel’s architecture, when run at a core voltage of 1.8V,
allows the KS8001 to dissipate an ultra-low 250mW in
power.Thistranslatestoincreasedreliabilitywhileenabling
deployment in today’s power-sensitive applications. Mul-
tiple power-down modes, accessed via conguration pins
or registers, allow further levels of power saving through
manual selection or automatic detection of cable energy.

Physical Layer Transceiver
Description
LinkMDTM cable diagnostics, an industry rst for single-
port Fast Ethernet PHYs, detects common cabling plant
problems such as open and short circuits. Diagnosis and
elimination of cabling faults can lead to reduced user
frustrationandfewerequipmentreturns,bothinenterprise
and consumer electronics applications. Combined with
HP Auto-MDIX, deployment is dramatically simplied
by providing the most robust solution for automatically
adjusting to crossover and straight-through cables.
The KS8001 represents a new level of features and
performance, and is an ideal choice of physical layer
transceiverfor10BASE-T,100BASE-TX,and100BASE-
FX applications.
