KSZ9131RNXI Gigabit Ethernet PHY, industrial Ethernet transceiver
The KSZ9131RNXI is a high-performance, single-port Gigabit Ethernet PHY from Microchip Technology, designed for industrial automation, enterprise networking, and embedded communication systems. This IEEE 802.3 compliant transceiver supports 10/100/1000BASE-T operation with RGMII and SGMII MAC interfaces, enabling seamless integration with FPGAs, processors, and switches. The device features advanced cable diagnostics, including open/short detection and length measurement, simplifying network troubleshooting in factory control systems and smart infrastructure. Its low-latency operation (<400ns) and energy-efficient Ethernet (EEE) support make it ideal for real-time industrial protocols (EtherCAT, PROFINET) and power-sensitive IoT gateways.
The KSZ9131RNXI incorporates robust ESD protection (±8kV contact discharge) and industrial temperature range (-40°C to +85°C), ensuring reliability in harsh electrical environments. Its programmable DSP-based equalization compensates for long cable runs (up to 150m), while auto-MDI/MDIX eliminates crossover cable requirements. Packaged in a compact 48-pin QFN (6x6mm), the PHY supports jumbo frames (9KB) and VLAN tagging for high-throughput data transmission. Microchip provides complete Linux drivers and hardware design guides, accelerating deployment in machine vision systems, medical devices, and 5G fronthaul equipment.
