Ruggedized Gigabit Ethernet PHY RMII/RGMII Transceiver with High Reliability and Extended Temperature for Aerospace and Military Ground-Based Applications
Microchip Technology has unveiled a new ruggedized Commercial-Off-The-Shelf (COTS) Gigabit Ethernet PHY RMII / RGMII transceiver for aerospace and military ground-based applications. Named VSC8540/41ET, the transceiver features a military-grade, high-reliability (HiRel) plastic package to meet requirements for applications of fighting vehicles to cockpit avionics and in-flight communication systems.
As COTS-based technology, the transceiver allows system designers to begin implementation with COTS devices before moving to military-grade components, reducing significant development time and cost. The VSC8540ET device is the extended temperature -55°C/+125°C version of the popular VSC8540 single-port Gigabit Ethernet copper PHY targeting space-constrained 10/100BASE-T applications.
The VSC8540ET is designed for space-constrained 10BASE-TX and EtherCAT applications. It comes endowed with integrated line-side termination to conserve board space, lower EMI, and improve system performance. Additionally, integrated RGMII version 2.0 standard timing compliant compensation eliminates the need for onboard delay lines. Wafer and assembly lot full traceability, description of testing, electrical parameters and fault coverage, qualification report, and certificate of compliance are the standout features of the transceiver.
The device complements the Micrchip’s extended-temperature product offering that includes the 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
