Microchip Technology, Inc. Drivers, Receivers, Transceivers KSZ9031RNXVA

The KSZ9031RNXVA is a single-chip Gigabit Ethernet transceiver designed for IEEE 802.3 applications, supporting data rates of 10/100/1000 Mbps. It features RGMII timing with on-chip delay adjustments, making it suitable for various applications that require precise timing control. The device operates with I/O voltage tolerances of 3.3V, 2.5V, or 1.8V and includes auto-negotiation capabilities to select the highest link speed and duplex mode automatically. This transceiver incorporates on-chip termination resistors and an LDO controller for efficient power management, requiring only one external FET to generate a 1.2V core supply. It supports jumbo frames up to 16 KB and includes energy detect power-down modes to minimize power consumption when not in use. Additional features include Wake-On-LAN support, programmable LED outputs for link status, and advanced diagnostics such as LinkMD TDR-based cable diagnostics and loopback modes. The KSZ9031RNXVA is AEC-Q100 qualified for automotive applications and comes in a compact 48-pin QFN package, making it suitable for a wide range of applications including network printers, NAS devices, routers, and automotive in-vehicle networking.
