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
