High-reliability, extended-temperature Ethernet PHY transceiver

Microchip has announced the VSC8540/41 Gigabit Ethernet PHY RMII/RGMII transceiver, a Commercial Off-The-Shelf (COTS)-based device that's been upgraded for avionics and military applications.

Based on its COTS technology deployed in other industries, 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 transceiver is a solution with 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 125C. Product specifications include wafer and assembly lot full traceability; description of testing, electrical parameters and fault coverage; qualification report; and certificate of compliance.

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

Microchip’s RMII/RGMII transceiver is the latest high-reliability solution designed for extreme environments and complements the company’s extended-temperature product offering that includes following qualified devices:

  • 8-bit AVR microcontrollers with embedded ADC/DAC, Controller Area Network (CAN) and motor control interfaces
  • 16-bit dsPIC digital signal controller for digital power management
  • 32-bit ARM microcontroller with memory protection mechanisms and 100 Mbit Ethernet connectivity
  • 200 Megasamples Per Second (Msps) standalone 16-bit ADC
