KSZ8001L/S

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

Physical Layer Transceiver

Data Sheet Rev. 1.04

General Description

Features

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.

•

Single chip 100BASE-TX/100BASE-FX/10BASE-T

physical layer solution

•

1.8V CMOS design, power consumption 250 mW

Robust (130m+) operation over standard cables

Supports Media Independent Interface (MII), Reduced

MII (RMII), and Serial MII (SMII)

•

LinkMD feature to determine cable length and

diagnose faulty cables up 200 m with +/- 2 m accuracy

Supports HP MDI/MDI-X auto crossover

Supports power down mode and power saving mode

MDC/MDIO to 12.5 MHz for rapid configuration

Fully compliant to IEEE 802.3u standard

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.

Supports auto-negotiation and manual selection for

10/100Mbps speed and full / half-duplex mode
