1.0 Introduction

The KSZ9031MNX is a completely integrated triple speed (10Base-T/100Base-TX/1000Base-T)

Ethernet Physical Layer Transceiver for transmission and reception of data on standard CAT-5

unshielded twisted pair (UTP) cable.

The KSZ9031MNX reduces board cost and simplifies board layout by using on-chip termination

resistors for the four differential pairs and by integrating a LDO controller to drive a low cost

MOSFET to supply the 1.2V core.

On the copper media interface, the KSZ9031MNX can automatically detect and correct for

differential pair misplacements and polarity reversals, and correct propagation delays and re-sync

timing between the four differential pairs, as specified in the IEEE 802.3 standard for 1000Base-T

operation.

The KSZ9031MNX provides the industry standard GMII/MII (Gigabit Media Independent Interface

/ Media Independent Interface) for connection to GMII/MII MACs in Gigabit Ethernet Processors

and Switches for data transfer at 1000 Mbps or 10/100Mbps speed.

The KSZ9031MNX Evaluation Board (KSZ9031MNX-EVAL) provides a comprehensive platform

to evaluate the KSZ9031MNX features. All KSZ9031MNX configuration pins are accessible either

by jumpers, test points or interface connectors.

4.0 Hardware Description

The KSZ9031MNX-EVAL board is the evaluation platform for the KSZ9031MNX Gigabit Ethernet

Transceiver. Configuration of the KSZ9031MNX is accomplished through on-board jumper

selections and/or by PHY register access via the KSZ9031MNX MDC/MDIO management pins

via the USB port (CN1).

Figure 1. KSZ9031MNX-EVAL Board

Features include a RJ-45 Jack for 10/100/1000 Ethernet speed cable connection, programmable

LED indicators for reporting link status and activity, and a manual reset button for quick reboot

after re-configuration of strapping pins.

GMII receive output clock and signals can be looped back to GMII transmit input clock and

signals to provide a standalone platform to evaluate the KSZ9031MNX device in 1000Mbps

mode.

MII Port (J1) provides the 10/100 MAC interface connections to Micrel KSZ88xx 3-port Switch

evaluation boards with the mating MII MAC interface connectors.

The KSZ9031MNX-EVAL board receives power from a DC power jack (J2). Any DC power

adapter in the range of 5V to 12V with a current rating of 2 Amp or better can also be used.

4.1 Jumper Setting & Definition

At power-up, the KSZ9031MNX device is configured via strapping pins that are set by external

pull-up and pull-down resistors. The KSZ9031MNX-EVAL board provides jumpers for the

KSZ9031MNX device strap-in settings and for selective board options.

Jumpers allow for quick configuration and re-configuration. To override the current KSZ9031MNX

device and board settings, simply select and close the desired jumper setting(s) and toggle the

on-board manual reset button (S1) for the new setting(s) to take effect.

The KSZ9031MNX-EVAL board jumper settings are defined in the table below.

4.3 RJ-45 Copper Interface

The RJ-45 copper interface (RJ1) connects to standard unshielded twisted pair (UTP) CAT-5

Ethernet cable to interface with 10Base-T/100Base-TX/1000Base-T network devices.

The KSZ9031MNX copper media interface can automatically detect and correct for differential

pair misplacements and polarity reversals, and correct propagation delays and re-sync timing

between the four differential pairs, as specified in the IEEE 802.3 standard for 1000Base-T

operation.

Auto MDI/MDI-X is supported for automatic detection and correction for straight and crossover

cables when interfacing to link partners with fixed MDI or MDI-X setting.

4.4 LED Indicators

The KSZ9031MNX device provides two programmable LED output pins, LED2 (pin 17) and LED1

(pin 19). On the KSZ9031MNX-EVAL board, these two LED pins are connected to two sets of

LEDs to support two LED configurations: Single LED mode and Tri-color Dual LED mode.

4.4.1 Single LED Mode

To enable Single LED mode,

•Close pins (1, 2) of jumpers JP7 and JP8 to select D2 and D3, respectively for the single

LEDs.

•Close pins (1, 2) of jumper JP9 to set the LED_MODE strap-in for Single LED mode.

•Power-up the board.
