KSZ9131RNXI
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.
