VSC854xRT Radiation Tolerant Ethernet PHY
Single-Port Fast/Gigabit Ethernet Copper PHY With GMII/RGMII/MII/RMII Interfaces
Summary
The VSC8541RT is a radiation-tolerant single-port Gigabit Ethernet copper PHY with GMII/RGMII/MII/RMII interfaces. The VSC8541RT withstands the harsh aerospace environment with enhanced radiation performances, extreme temperature, vacuum and high reliability.
Targeting space-constrained 10/100/1000BASE-T applications in both ceramic and plastic packages, the VSC8541RT supports the widest range of LVCMOS levels for a parallel MAC interface as well as the MDIO/MDC interface.
