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). Figure 1.

SN65HVD101 EVM Board Layout 3 EVM Setup and Precautions To evaluate the performance of the SN65HVD101 you need the following equipment: 1. Power supply capable of supplying 3.3 V. 5 V if using the SN65HVD102 device. 2. Power supply capable of supplying 24 V across Lp (supply) and Ln (GND), if using the SN65HVD101 device. 3. Oscilloscope note: The IO-Link uses industrial 24-V signaling; oscilloscope probes should be chosen which will not be damaged by voltage levels up to 30 V. 4. IO-Link Master Node with appropriate 3-wire cable with Lp, Ln and CQ signals. 5. Local microcontroller, or equivalent, to communicate with the SN65HVD10x IO-Link PHY via the controller interface pins. 3.1 SN65HVD101 EVM Setup With an appropriate IO-Link cable, connect the Lp, Ln, and CQ pins from TB1 on the EVM board to an IOLink Master node. 3.3-V or 5-V supply operation On JMP2 if a shunt is placed on VCC_SET to GND, the internal voltage regulator will supply 3.3 V. If no shunt is placed on JMP2, the VCC_SET input will float and the internal regulator will supply 5 V. On the SN65HVD101 device, VCC_IN is a voltage-sense feedback signal. When using the SN65HVD101 EVM, place a shunt over VCC_IN and VCC_OUT on JMP8.

Placing a shunt across 20K (pins 1-2) on JMP1 limits the current at the CQ pin to 100 mA. Placing a shunt across GND (pins 3-4) on JMP1 limits the current to 400 mA. When working with the SN65HVDHVD102 EVM, leave the shunt off and provide the 3.3-V or 5-V supply to the VCC_IN terminal. Microcontroller / IO-LINK Interface Signals From the microcontroller, connect the EN (enable) signal to the EN post on JMP5, the microcontroller TX signal to the EVM TX post on JMP4, the RX signal to the RX post on JMP3. Connect the master’s WAKE signal to the WAKE post on JMP9, and the master CUR_OK signal to the CURR_OK post on JMP9. An example is shown below in Figure 3.
