High-reliability Ethernet PHY transceiver targets aerospace and military applications
A ruggedized Commercial-Off-The-Shelf (COTS) Gigabit Ethernet PHY transceiver from Microchip is aimed at aircraft, military vehicles and communication systems

Microchip Technology has launched a high reliability exteneded temperature Gigabit Ethernet PHY RMII / RGMII Transceiver for aircraft, military vehicle and ground-based systems.

The VSC8540/41 is a Commercial Off-The-Shelf (COTS)-based device upgraded for avionics and military applications. It 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.

It uses the Reduced Gigabit Media Independent Interface (RGMII) and G.M.I.I., and also supports R.M.I.I and M.I.I. Megabit interface. The transceiver is latch-up immune to atmospheric radiation effects while performing at a temperature range of –55 to 125 degrees Celsius. Product specifications include wafer and assembly lot full traceability; description of testing, electrical parameters and fault coverage; qualification report; and certificate of compliance.

As COTS-based technology, Microchip’s Ethernet PHY RMII / RGMII transceiver allows system designers to begin implementation with COTS devices before moving to military-grade components, reducing significant development time and cost.

The device can be used with Microchip's extended-temperature qualified devices such as the 8bit AVR microcontrollers with embedded ADC/DAC, Controller Area Network (CAN) and motor control interfaces, 16bit dsPIC digital signal controller for digital power management and 32bit ARM microcontroller with memory protection mechanisms and 100 Mbit Ethernet connectivity, as well as a standalone 16-bit ADC that supports 200 Megasamples Per Second (Msps).

Microchip also teams with system manufacturers and integrators on obsolescence management, supporting efforts to minimize redesign work and lengthen life cycles, thereby reducing overall system costs.

The VSC8540/41 Gigabit Ethernet PHY RMII / RGMII transceiver in a plastic or ceramic package is now sampling.
