Add To BomKSZ9031RNXVB-VAO General Description
The KSZ9031 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 unshielded twisted pair (UTP) cable.
The KSZ9031MNX 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 KSZ9031RNX provides the reduced gigabit media independent interface (RGMII).
The KSZ9031 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 KSZ9031 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 KSZ9031 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 KSZ9031RNX is available in the 48-pin, lead-free QFN package, and the AEC-Q100 automotive qualified parts, KSZ9031RNXUB-VAO and KSZ9031RNXVB-VAO, are available in the 48-pin lead-free WQFN package. The KSZ9031MNX is available in a 64-pin, lead-free QFN package.
