KSZ9031RNX Key Features
- Single-chip 10/100/1000Mbps IEEE 802.3 pliant Ethernet transceiver
- RGMII timing supports on-chip delay according to RGMII Version 2.0, with programming options for external delay and maki
- RGMII 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
