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 fi 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. This translates to increased reliability while enabling
deployment in today’s power-sensitive applications. Mul-
tiple power-down modes, accessed via confi guration pins
or registers, allow further levels of power saving through
manual selection or automatic detection of cable energy.

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
frustration and fewer equipment returns, both in enterprise
and consumer electronics applications. Combined with
HP Auto-MDIX, deployment is dramatically simplifi ed
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
transceiver for 10BASE-T, 100BASE-TX, and 100BASE-
FX applications.
