2 EVM Overview

2.1 Evaluating the SN65HVD10x

The SN65HVD10x IO-LINK PHYs implement the IO-LINK interface for industrial point-to-point

communication. When the device is connected to an IO-Link master through a 3-wire interface, the device

will respond to communication initiated by the master. These PHY devices will exchange data with the

Master node, acting as a complete physical layer for bi-directional communication. The SN65HVD101

device integrates a linear regulator that generates either 3.3 V or 5 V from the 24-V-nominal IO-Link L+

voltage for supplying power to the PHY as well as a local controller and additional circuits. The

SN65HVD102 operates from an external 3.3-V or 5-V local supply connected to VCC_IN and GND on TB2

(see Figure 1 and Figure 2 for location).
