KSZ9031MNXIA TR

MICREL SEMICONDUCTOR  KSZ9031MNXIA TR  芯片, 收发器, 千兆位以太网物理层, 1端口, 64QFN

The 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 cable. It 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. It 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. It 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 KSZ9031MNX I/Os and the board. The LinkMD® TDR-based cable diagnostic identifies faulty copper cabling.
