2 ADS9817EVM Quick Start Guide
The following instructions are a step-by-step guide to connecting the ADS9817EVM to the computer and
evaluating the performance of the ADS9817:
1. Review the default jumper settings in
2. Physically connect J1 of the TSWDC155EVM to J27 of the ADS9817EVM. This component is the digital
communications and power signal connection in default configuration.
3. Set jumper J18 to the FMC_PWR position so the TSWDC155EVM provides power. Otherwise, set J18 to
EXT_PWR and connect an external 5.2-V to 5.5-V supply on screw terminal connection J17.
4. Bypass any external USB hub and connect the USB on the TSWDC155EVM directly to the computer.

1. Start the software GUI as described in
2. Press the Initialize USB, Power Up, Program FPGA, and Initialize ADS98xx buttons, in order from top to
bottom, on the Config tab to power up and configure the EVM, as shown in
details).
3. Connect a +/-5-V, single-ended sine wave signal from a function generator to any AINxP SMA input
connector.
4. Press the EN SYNC button on the Capture tab.
5. Select the number of samples to be at least 32k points, and choose the Hanning window type for best
frequency domain results.
6. Press the Start Capture button to collect and analyze the data displayed on the appropriate CHx tab; see
