Description
General part information
LAN8831 Series
The LAN8831 is an integrated triple-speed (10Base-T/100Base-TX/1000Base-T) Ethernet physical-layer transceiver for transmission and reception of data on standard CAT-5, CAT-5e and CAT6 unshielded twisted pair (UTP) cable. It provides RGMII (Reduced Gigabit Media Independent Interface) and GMII/MII (Gigabit Media Independent Interface/Media Independent Interface) for connection to Ethernet MACs in processors and switches for data transfer at 1000Mbps or 10/100Mbps.
The LAN8831 reduces board cost and simplifies board layout by using on-chip termination resistors for the four differential pairs and by integrating an LDO controller to drive a low-cost MOSFET to supply the 1.1V core.
The LAN8831 offers diagnostic features to facilitate system bring-up and debugging in production testing and in product deployment. Parametric NAND tree support enables fault detection between LAN8831 I/Os and the board. The LinkMD® TDR-based cable diagnostic identifies faulty copper cabling. Remote and local loopback functions verify analog and digital data paths.
