KS8001L

1.8V, 3.3V 10/100BASE-T/TX/FX Physical Layer Transceiver

Micrel 

General Description

The KSZ8001 is a 10BASE-T/100BASE-TX/100BASE-FX

Physical Layer Transceiver, operating the core at 1.8 volts

to meet low voltage and low power requirements. The

solution provides MII/RMII/SMII interfaces to transmit and

receive data. A unique mixed-signal design extends

signaling distance while reducing power consumption.

HP Auto MDI/MDI-X provides the most robust solution for

eliminating the need to differentiate between crossover and

straight-through cables.

Featuring LinkMD cable diagnostics, which allows

detection of common cabling plant problems such as open

and short circuits, the KSZ8001 represents a new level of

features and performance and is an ideal choice of

physical layer transceiver for 100BASE-TX/10BASE-

T/100BASE-FX applications.
