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.
