KSZ9031RNXIA-TR Microchip

The KSZ9031RNXIA-TR is a 1-Port Gigabit Ethernet Media Access Controller and Physical Layer (PHY) device designed to work with the industry standard 10/100/1000Base-T Ethernet standard. This Ethernet IC is manufactured by Microchip and it features a 32-bit RISC-based processor, SPI and MDC/MDIO interfaces, dedicated I/O for 10/100/1000M autonegotiation, Automatic MDI/MDI-X crossover detection, dual-port switch control support, and a number of other features. The integrated digital servo loop enables the device to deliver an accuracy of better than 250ppm for reference clock output. Additionally, the KSZ9031RNXIA-TR supports low power sleep modes and dynamic power management.
