Bom Sourcing Integrated Circuit IC Chip KSZ9031RNXIC 4/4 Transceiver Full Ethernet 48-QFN

KSZ9031RNXIC 4/4 Transceiver Full Ethernet 48-QFN

Features

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

Ethernet transceiver

• RGMII timing supports on-chip delay according to

RGMII Version 2.0, with programming options for

external delay and making adjustments and corrections

to TX and RX timing paths

• RGMII with 3.3V/2.5V/1.8V tolerant I/Os

• 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

• 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
