KSZ9031RNX1C-TR – MICROCHIP

The Microchip Technology KSZ9031RNX1C-TR is a single-port Gigabit Ethernet transceiver designed for high-performance networking applications. This RGMII (Reduced Gigabit Media Independent Interface) PHY offers robust signal integrity and low latency, making it suitable for real-time applications. It supports both copper and fiber media via external components. The device operates with a typical I/O voltage range of 3.3V. It features integrated termination resistors, minimizing external component count and board space. Packaged in a 48-pin QFN SMD format, it’s well-suited for automated assembly processes. The KSZ9031RNX1C-TR operates reliably over a temperature range of –40°C to 85°C. A key advantage is its energy-efficient Ethernet (EEE) support, reducing power consumption during periods of low network activity. The output is rated for 1.2V and is designed to deliver a current of 20mA. Its common use cases include industrial Ethernet, embedded systems, and high-speed data acquisition.
