KSZ9031MNXIC

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.

KSZ9031是一款完全集成的三速(10Base-T/100Base-TX/1000Base-T)以太网物理层收发器，用于在标准CAT-5非屏蔽双绞线(UTP)电缆上发送和接收数据。

KSZ9031MNX提供行业标准的GMII/MII(千兆位媒体独立接口/媒体独立接口)，用于连接到千兆位以太网处理器和交换机中的GMII/MII MAC，以1000Mbps或10/100Mbps的速度传输数据。KSZ9031RNX提供精简的千兆位媒体独立接口(RGMII)。

KSZ9031对四个差分对使用片内端接电阻，并集成一个LDO控制器来驱动低成本MOSFET为1.2V内核供电，从而降低电路板成本并简化电路板布局。KSZ9031提供诊断功能，有助于生产测试和产品部署中的系统启动和调试。参数NAND树支持实现ksz 9031 I/o和电路板之间的故障检测。基于LinkMD TDR的电缆诊断可识别有故障的铜缆。远程和本地回送功能验证模拟和数字数据路径。

标准KSZ9031RNX采用48引脚无铅QFN封装，AEC-Q100汽车认证器件KSZ9031RNXUB-VAO和KSZ9031RNXVB-VAO采用48引脚无铅WQFN封装。KSZ9031MNX采用64引脚无铅QFN封装。
