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.
