General Description

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

Features

? 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

? Auto-negotiation to automatically select the highest linkup 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

? Jumbo frame support up to 16KB

? 125MHz reference clock output

? Energy-detect power-down mode for reduced power 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 detection

? Programmable LED outputs for link, activity, and speed

? Baseline wander correction

? LinkMD TDR-based cable diagnostic to identify faulty copper cabling

? Parametric NAND tree support to detect faults between chip I/Os and board.

? Loopback modes for diagnostics

? Automatic MDI/MDI-X crossover to detect and correct pair swap at all speeds of operation

? Automatic detection and correction of pair swaps, pair skew, and pair polarity

? MDC/MDIO management interface for PHY register configuration

? Interrupt pin option

? Power-down and power-saving modes

? Operating voltages

– Core (DVDDL, AVDDL, AVDDL_PLL): 1.2V (external FET or regulator)

– VDD I/O (DVDDH): 3.3V, 2.5V, or 1.8V

– Transceiver (AVDDH): 3.3V or 2.5V (commercial temp)

? Available in a 64-pin QFN (8mm x 8mm) package

Applications

? Network attached storage (NAS)

? Network server

? Broadband gateway

? Gigabit SOHO/SMB router

? IPTV

? IP set-top box

? Game console

? IP camera

? Triple-play (data, voice, video) media center

? Media converter
