4.1.3 Steps to Start Automatic Configuration

  1. Start the HSDC PRO software by going to Start > Texas Instruments > High Speed Data Converter Pro. Figure 4-1 illustrates that the HSDC PRO application started properly. Take note of the Serial Numbers of the TSW14J56EVM after the device is connected.

  3. Start the Latte software by going to Start > Texas Instruments > Latte. Ensure that the Latte software starts properly.
  4. On the left side of the Latte application, within the Scripts window, expand AFE79xx > Automation > AFE79xx_TSW14J56_Mode1.py. Figure 4-3 shows the python script.

  5. Change three parameters within the AFE79xx_TSW14J56_Mode1.py per the directory used by the HSDC PRO and Latte software.
  6. Figure 4-4 shows where to change items 1 and 2 to reflect the location of the Latte install directory for the setup.py and devInit.py. Typically, the area where a0xxxxxx is replaced with the Windows user ID login.

  7. Figure 4-4 shows where to change item 3 to reflect the location of the High-Speed Data Converter Pro directory for the TSW14J56 firmware.
  8. Figure 4-5 shows where to enter the serial number of the TSW14J56 EVM per the highlighted line.

  9. With the AFE79xx_TSW14J56_Mode1.py highlighted, press the F5 button to execute the script. The script automates both the HSDC PRO and Latte software to automatically bring up the JESD204B link.
  10. Figure 4-6 and Figure 4-7 show the expected following two error messages after the script runs.

  11. The default TRF-LSC-AFE7950EVM has the following RF frequency matching network:
    1. RXA (TRF1208): 1.8GHz–2.3GHz
    2. RXB (TRF1208): 4.8GHz–5.5GHz
    3. RXC (TRF1208): 7.3GHz–7.8GHz
    4. RXD (Balun): None
    5. FB1 (TRF1208): 5.8GHz–6.2GHz
    6. FB2 (Differential connectors): 6GHz
    7. TXA (TRF1108): 1GHz–5GHz
    8. TXB (Balun): 3.9GHz–4.3GHz
    9. TXC (TRF1108): 700MHz–8GHz
    10. TXD (TRF1108):2.5GHz–4.5GHz
  12. The example script to change the NCO to match the default RF frequency matching network is the following: 
    AFE.updateTxNco(0,200,0,0)
AFE.updateTxNco(1,5000,0,0)
AFE.updateTxNco(2,7500,0,0)
AFE.updateTxNco(3,3000,0,0)
AFE.updateRxNco(0,2100,0,0)
AFE.updateRxNco(1,5200,0,0)
AFE.updateRxNco(2,7800,0,0)
AFE.updateRxNco(3,6000,0,0)
AFE.updateFbNco(0,6000,0)
AFE.updateFbNco(1,6000,0)
  13. Figure 4-8 shows where to enter the commands in the command line prompt or execute AFE79xx_DC101_NCO_Setup.py (under the AFE79xx > Automation folder) in the Latte using the F5 key.
