KSZ9031RNX Description
The KSZ9031RNX is a pletely integrated triple-speed (10Base-T/100Base-TX/1000Base-T) Ethernet physicallayer transceiver for transmission and reception of data on standard CAT-5 unshielded twisted pair (UTP) cable. The KSZ9031RNX provides the Reduced Gigabit Media Independent Interface (RGMII) for direct connection to RGMII MACs in Gigabit Ethernet processors and switches for data transfer at 10/100/1000Mbps.

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
