Products Detail

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.

The KSZ9131 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 KSZ9131 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.

The standard KSZ9131RNX is available in the 48-pin, RoHS compliant QFN package, and the AEC-Q100 automotive qualified parts, KSZ9131RNXU and KSZ9131RNXV, are available in the 48-pin lead-RoHS compliant VQFN (wettable) package. The KSZ9131MNX is available in a 64-pin, RoHS Compliant QFN package.

Microchip's complimentary and confidential MicroCHECK design review service, which offers insight from the initial concept to the final PCB layout, is available to customers who are using our products in their projects. You can confidently submit your design materials in a secure and private setting, and our expert engineers will provide individualized feedback to enhance your design. MicroCHECK design review service is subject to Microchip's Program Terms and Conditions and requires a myMicrochip account.
