Original Ethernet IC, Supply Microchip KSZ9131RNXI Gigabit Ethernet Transceiver

Shenzhen Mingjiada Electronics Co., Ltd.——Long Term Supply Microchip (KSZ9131RNXI) Gigabit Ethernet Transceiver with RGMII Support. Below are product details for Ethernet Transceiver KSZ9131RNXI:

KSZ9131RNXI 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.

KSZ9131RNXI provides Reduced Gigabit Media Independent Interface RGMII for connection to GMII/MII MACs in Gigabit Ethernet processors and switches for data transfer at 1000Mbps or 10/100Mbps.

KSZ9131RNXI 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.

KSZ9131RNXI 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 KSZ9131RNXI 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.
