Device Overview

Summary

The VSC8540RT device is a radiation tolerant single port Fast Ethernet copper PHY targeting space-constrained 10/100BASE-T applications. The VSC8540RT withstands the harsh aerospace environment with enhanced radiation performances, extreme temperatures, vacuum and high reliability. It features integrated, line-side termination to conserve board space, lower EMI, and improve system performance.
Additionally, integrated RGMII timing compensation eliminates the need for on-board delay lines.
The device supports the industry’s widest range of LVCMOS levels for a parallel MAC interface including: 1.5 V, 1.8 V, 2.5 V, and 3.3 V, as well as 1.2 V, 1.5 V, 1.8 V, 2.5 V, and 3.3 V support on the MDIO/MDC interface.
This space-qualified version of the product adds:  Ceramic & Hermetic packages, extended temperature range -40C to +125C, extended qualification flow equivalent to QML-V or QML-Q space grade. 

Additional Features
  • EcoEthernet\u2122 2.0, with Energy Efficient Ethernet (EEE)
  • Fast Link Failure\u2122 2.0 (FLF2) with failure indication for commutator ring applications
  • Widest voltage range, fully-compliant parallel MAC interface device
  • Synchronous Ethernet support
  • Small 8 mm x 8 mm QFN package
  • Configurable drive strength on MAC interface enables better control of system-level EMI/EMC
  • Radiation Performances
    • No Single Event Latch-up Below an LET Threshold of 78 MeV.cm2 /mg @125°C
