Table 1. Switches to set the 4-level input control pins
4 – level Input Settings
Setting for 3 pin switches (3-2-1)
ON – OFF – OFF
0 – Tie 1k ohm to GND
OFF – ON – OFF
R – Tie 20k ohm to GND
F – FLOAT (open)
OFF – OFF – OFF
OFF – OFF – ON
1 – Tie 1k ohm to VIH
The following switches are used to set the input condition for the 4-level inputs:
SW1, SW2, SW3, SW5, SW6, SW8, SW9.
There are 3 switches connected to an input signal pin. Each switch when set to the ON position sets the pin to one
of the 4-level setting. The 6 pin switches are assigned similar to the 3 pin switches. The only difference is 2 signal
pins are connected and thus 6-5-4 is for the one signal pin and 3-2-1 is for another signal pin. Please note only 1
switch at the ON position is allowed.

SW9 – RXDET = F (continuous receiver detection): set switches (3-2-1) = (OFF-OFF-OFF).
RXDET = 1 (50 ohm input termination): set switches (3-2-1) = (OFF-OFF-ON).
SW9 – RATE = 1 (GEN3 mode with DEM control): set switches (6-5-4) = (OFF-OFF-ON).
RATE = F (enable rate detection for GEN1,2,3 with DEM control): set switches (6-5-4) to (OFF-OFF-OFF).
RATE = R (GEN3 mode without DEM control): set switches (6-5-4) = (OFF-ON-OFF).
RATE = 0 (GEN1,2 mode with DEM control): set switches (6-5-4) = (ON-OFF-OFF).
SW6 – SD_TH = F (default signal detect threshold level): set switches (3-2-1) = (OFF-OFF-OFF).
SW6 – LPBK = F (normal operation): set switches (6-5-4) = (OFF-OFF-OFF).
2.5. Set the input equalization level
For external pin mode control of the equalization level:
Set ENSMB = 0 (1kohm to GND) by using the SW2 (3-2-1) = (ON-OFF-OFF).
SW4 pin1,2 must be set to the OFF positions, so the SMBUS signals are disconnected.

EVALUATION BOARD/KIT/MODULE (EVM)
WARNINGS, RESTRICTIONS AND DISCLAIMERS
For Feasibility Evaluation Only, in Laboratory/Development Environments. Unless otherwise indicated, this
EVM is not a finished electrical equipment and not intended for consumer use. It is intended solely for use for
preliminary feasibility evaluation in laboratory/development environments by technically qualified electronics experts
who are familiar with the dangers and application risks associated with handling electrical mechanical components,
systems and subsystems. It should not be used as all or part of a finished end product.
Your Sole Responsibility and Risk. You acknowledge, represent and agree that:
1. 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.
2. 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.
3. 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.
4. 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
