Description

General part information

KSZ9131 Series

The KSZ9131 is a completely 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.

The KSZ9131RNX provides Reduced Gigabit Media Independent Interface RGMII and the KSZ9131MNX offers the industry-standard GMII/MII (Gigabit Media Independent Interface/Media Independent Interface) for connection to GMII/MII MACs in Gigabit Ethernet processors and switches for data transfer at 1000Mbps or 10/100Mbps.

The KSZ9131 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 1.2V core.
