2.1 ADS9327EVM Quick Start Guide

The following instructions are a step-by-step guide to connecting the ADS9327EVM to the computer and evaluating the performance of the ADS9327. Review the default jumper settings and power guidelines in Figure 2-1.

  1. Physically connect J1 of the TSWDC155EVM to the J4 of the ADS9327EVM. The TSWDC155EVM is the digital communications and power signal connection in the default configuration in Figure 2-1.
  2. Set jumper JP2 to the "INT" [1-2] position so that the TSWDC155EVM provides power to the on-board DC/DC and LDO circuits. If external power supplies are preferred, set JP2 to "EXT" [2-3] and connect an external 5.2V to 5.5V supply on screw terminal connection J5.
  3. Connect connect the USB on the TSWDC155EVM directly to the computer.

  4. Install the GUI as described in Section 3.2.1.
  5. Launch the GUI.
  6. Press the Initialize USB, Power Up, Program FPGA, and Initialize ADS9327 buttons, in order from top to bottom, on the Config tab to power up and configure the EVM. See Section 3.2.2 for details.
  7. Connect an 8VPP, differential sine wave signal from a function generator to at least one pair of differential inputs of the ADC channels through the SMA input connectors:
    1. Channel A: AINP_A (J9) and AINM_A (J10)
    2. Channel B: AINP_B (J7) and AINM_B (J8)
  8. Set the number of samples to a minimum of 128k points, and choose the Hanning window type for best frequency domain results.
  9. Press the Start Capture button to collect and analyze the data displayed on the appropriate CHx tab; see Section 3.2.3.
