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).

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.

JMP1 sets the current limit. 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.

You have unique knowledge concerning Federal, State and local regulatory requirements (including but not limited to Food and Drug
Administration regulations, if applicable) which relate to your products and which relate to your use (and/or that of your employees,
affiliates, contractors or designees) of the EVM for evaluation, testing and other purposes.
You have full and exclusive responsibility to assure the safety and compliance of your products with all such laws and other applicable
regulatory requirements, and also to assure the safety of any activities to be conducted by you and/or your employees, affiliates,
contractors or designees, using the EVM. Further, you are responsible to assure that any interfaces (electronic and/or mechanical)
between the EVM and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to
minimize the risk of electrical shock hazard.
You will employ reasonable safeguards to ensure that your use of the EVM will not result in any property damage, injury or death, even
if the EVM should fail to perform as described or expected.
You will take care of proper disposal and recycling of the EVM’s electronic components and packing materials.
Certain Instructions. It is important to operate this EVM within TI’s recommended specifications and environmental considerations per the
user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power, and
environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact
a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the
specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or
interface electronics. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the
load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures
greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include
but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the
EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please
be aware that these devices may be very warm to the touch. As with all electronic evaluation tools, only qualified personnel knowledgeable
in electronic measurement and diagnostics normally found in development environments should use these EVMs.
Agreement to Defend, Indemnify and Hold Harmless. You agree to defend, indemnify and hold TI, its licensors and their representatives
harmless from and against any and all claims, damages, losses, expenses, costs and liabilities (collectively, "Claims") arising out of or in
connection with any use of the EVM that is not in accordance with the terms of the agreement. This obligation shall apply whether Claims
arise under law of tort or contract or any other legal theory, and even if the EVM fails to perform as described or expected.
Safety-Critical or Life-Critical Applications. If you intend to evaluate the components for possible use in safety critical applications (such
as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, such as devices
which are classified as FDA Class III or similar classification, then you must specifically notify TI of such intent and enter into a separate
Assurance and Indemnity Agreement.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
