6 ADS8900EVM-PDK Operation

The following instructions are a step-by-step guide to connecting the ADS8900BEVM-PDK to the computer and evaluating the performance of the ADS8900B:

  1. Connect the ADS8900VEVM to the PHI. Install the two screws as indicated in Figure 6-1.
  2. Connect the USB on the PHI to the computer first:
    • LED D5 on the PHI lights up, indicating that the PHI is powered up.
    • LEDs D1 and D2 on the PHI start blinking to indicate that the PHI is booted up and communicating with the PC. Figure 6-1 shows the resulting LED indicators.
  3. Start the software GUI as shown in Figure 6-2. Notice that the LEDs blink slowly when the FPGA firmware is loaded on the PHI. This process takes a few seconds and then the AVDD and DVDD power supplies turn on.
  4. Connect the signal generators to the SMA inputs. The input range is either a differential 10-VPP or a single-ended 10-VPP range.
