4.3 Setting up the ADC3643EVM

  1. Verify that the software is set up according to the Software Setup section.
  2. Verify that the hardware is set up according to the Hardware Setup section
  3. To provide the CLK signal:
    1. Using an SMA cable and an inline 65MHz band pass filter, connect the signal generator to the CLKp SMA connector (J5) on the ADC3643EVM.
    2. Set the output signal frequency of the signal generator to 65MHz and the signal amplitude to +10dBm.
  4. By default, the EVM is configured to take a single ended input, so analog inputs must be applied to connectors CHAp (J7) for Channel A or CHBp (J9) for Channel B. To provide an analog input:
    1. Using an SMA cable and an inline 5MHz band pass filter, connect the signal generator to analog input channel A.
    2. Set the output signal frequency of the signal generator to 5.135MHz (prime number) and 0dBm.
  5. To provide a DCLK signal:
    1. Using an SMA cable, connect the signal generator to the DCLKIN SMA connector (J6).
    2. Set the output frequency of the signal generator to 227.5MHz (14-bit, 2-wire, DDC bypass) and the signal amplitude to +2dBm.
  6. Verify that all signal generators for clock, analog input and DCLK are referenced locked using the 10MHz REF on the back of the signal generators. For an example of this, please see figure below.

  7. Your setup now looks like the following:

  8. Open HSDC Pro. Always verify that HSDC Pro is open before opening the ADC36xxEVM GUI.
  9. Select on cancel when prompted to connect to a board. The GUI handles all of the other HSDC Pro capture and configuration related operations.

  10. Open the ADC36xxEVM GUI. Allow a few seconds for the GUI to connect to the TSWDC155EVM FPGA Capture board. The TSWDC155EVM powers on, and several LEDs become illuminated, as shown below.

  11. Once the GUI is opened, verify that the correct ADC mode parameters are selected, then click on the “Calculate” button to calculate the necessary DCLK. For this mode, the DCLK must be 227.5MHz. Verify that this signal is provided to the DCLK input on the hardware setup.

  12. Select the “Program” button. Allow a few seconds to program the ADC, program the FPGA, and configure the FPGA firmware.

  13. Once programming is complete, select the "Capture" button to take an FFT data capture.

  14. After a few seconds, the captured data appears in the HSDC Pro window, where you can view the performance of the device. For more functions and features of HSDC Pro, see the HSDC Pro User Guide.

  15. If an error occurs when running the capture function, restart the GUI and follow steps 5-8 again.
