KSZ8051MNLU/KSZ8051RNLU

10Base-T/100Base-TX

Physical Layer Transceiver

Data Sheet Rev. 1.0

General Description

The KSZ8051 is an AEC-Q100 standard qualified single-

supply 10Base-T/100Base-TX Ethernet physical-layer

transceiver for transmission and reception of data over

standard CAT-5 unshielded twisted pair (UTP) cable for

automotive applications.

The KSZ8051 is a highly-integrated PHY solution. It reduces

board cost and simplifies board layout by using on-chip

termination resistors for the differential pairs and by

integrating a low-noise regulator to supply the 1.2V core.

The KSZ8051MNLU offers the Media Independent Interface

(MII) and the KSZ8051RNLU offers the Reduced Media

Independent Interface (RMII) for direct connection with

MII/RMII-compliant Ethernet MAC processors and switches.

A 25MHz crystal is used to generate all required clocks,

including the 50MHz RMII reference clock output for the

KSZ8051RNLU.

The KSZ8051 provides diagnostic features to facilitate

system bring-up and debugging in production testing and

in product deployment. Parametric NAND tree support

enables fault detection between KSZ8051 I/Os and the

board. Micrel LinkMD TDR-based cable diagnostics

identify faulty copper cabling.

The KSZ8051MNLU and KSZ8051RNLU are available in

32-pin, lead-free QFN packages (see “Ordering

Information”).

Data sheets and support documentation are available on

Micrel’s web site at:
