2 Introduction
The DP83561-SP is a radiation hardened, high reliability gigabit Ethernet PHY designed for hostile environments
like those found in space, avionics, or downhill drilling. The DP83561-SP is a low power, fully featured Physical
Layer transceiver with integrated PMD sub-layers to support 10BASE-Te, 100BASE-TX and 1000BASE-T
Ethernet protocols.
The DP83561EVM is a tool used to highlight the features of the DP83561-SP Ethernet PHY. Breakout
connectors are included to allow MAC access and back-to-back configuration support. The EVM also provides
on-board tools to configure PHY registers using a USB-MDIO graphical user interface tool. The EVM can be
powered by a single Wide-Vin 5V-36V power supply or through a microUSB cable.
Note
The DP83561EVM uses DP83561-SP Engineering Module (EM) parts. EM parts do not ensure
radiation performance. They are suitable for prototyping but not suitable for production.
