KSZ9031MNX

Gigabit Ethernet Transceiver

with GMII/MII Support

Data Sheet Rev. 1.0

General Description

Features

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.

• Single-chip 10/100/1000Mbps IEEE 802.3 compliant

Ethernet transceiver

• GMII/MII standard interface with 3.3V/2.5V/1.8V tolerant

I/Os

The KSZ9031MNX offers 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

1000Mbps or 10/100Mbps.

• Auto-negotiation to automatically select the highest link-

up speed (10/100/1000Mbps) and duplex (half/full)

• On-chip termination resistors for the differential pairs

• On-chip LDO controller to support single 3.3V supply

operation – requires only one external FET to generate

1.2V for the core

The KSZ9031MNX reduces board cost and simplifies

board layout by using on-chip termination resistors for the

four differential pairs and by integrating an LDO controller

to drive a low-cost MOSFET to supply the 1.2V core.

• Jumbo frame support up to 16KB

• 125MHz reference clock output

• Energy-detect power-down mode for reduced power

The KSZ9031MNX offers diagnostic features to facilitate

system bring-up and debugging in production testing and

in product deployment. Parametric NAND tree support

enables fault detection between KSZ9031MNX I/Os and

the board. The LinkMD^®TDR-based cable diagnostic

identifies faulty copper cabling. Remote and local loopback

functions verify analog and digital data paths.

consumption when the cable is not attached

• Energy Efficient Ethernet (EEE) support with low-power

idle (LPI) mode and clock stoppage for 100Base-TX/

1000Base-T and transmit amplitude reduction with

10Base-Te option

• Wake-on-LAN (WOL) support with robust custom-packet

The KSZ9031MNX is available in a 64-pin, lead-free QFN

package (see “Ordering Information”).
