CHANDLER, Ariz. Microchip Technology Inc. announced its new VSC8540/41ET Gigabit Ethernet PHY RMII / RGMII Transceiver – a Commercial Off-The-Shelf (COTS)-based device upgraded for avionics and military applications.

According to the company, Microchip’s Gigabit Ethernet Physical Layer (PHY) transceiver features a military-grade, high-reliability (HiRel) plastic package that meets requirements for applications ranging from fighting vehicles to cockpit avionics and in-flight communication systems. 

The VSC8541ET Ethernet transceiver is designed to be a solution with Reduced Gigabit Media Independent Interface (RGMII) and GMII, and also supports RMII and MII Megabit interface. 

The company also claims that the transceiver is latch-up immune to atmospheric radiation effects while performing at a temperature range of –55 to 125 degrees Celsius. As COTS-based technology, Microchip’s Ethernet PHY RMII / RGMII transceiver is intended to allow system designers to begin implementation with COTS devices before moving to military-grade components.
