The KSZ9131RNX Transceivers offer a Reduced Gigabit Media Independent Interface RGMII. 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 Gigabit Ethernet Transceivers reduce board cost and simplifies board layout, 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 has diagnostic features to facilitate system bring-up and debugging in production testing as well as 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.
