Microchip Technology Inc. has upgraded its commercial off-the-shelf (COTS) Gigabit Ethernet physical layer (PHY) transceiver technology for avionics and military applications. The new upgraded COTS device, the VSC8540/41ET Gigabit Ethernet PHY transceiver, is latch-up immune to atmospheric radiation effects while performing at a temperature range of -55°C to 125°C.
The VSC8541ET is a ruggedized version of the VSC8540 single-port Gigabit Ethernet copper PHY that is used in space-constrained 10/100BASE-T applications.
The new VSC8541ET features a military-grade, high-reliability (hi-rel) plastic package that meets requirements for applications ranging from fighting vehicles to cockpit avionics and in-flight communication systems. As COTS-based technology, the Ethernet PHY Reduced Gigabit Media Independent Interface (RGMII)/RGMII transceiver allows system designers to begin implementation with COTS devices before moving to military-grade components, reducing significant development time and cost, said Microchip.

The device includes Microchip’s EcoEthernet 2.0 technology with Energy Efficient Ethernet and power saving features to reduce power based on link state and cable reach. It also optimizes power consumption at all link operating speeds, and features Wake-on-LAN power management using magic packets, said Microchip.
Product specifications include wafer and assembly lot full traceability, description of testing, electrical parameters and fault coverage, qualification report, and certificate of compliance. The VSC8540/41ET PHY RMII/RGMII transceiver in a plastic or ceramic package is sampling now.
