4.1 Steps to Start Automatic Configuration

  1. Within the Microsoft®Windows® PC, start the HSDC PRO software by going to Start > Texas Instruments > High Speed Data Converter Pro. As shown in Figure 4-1, ensure that the High-Speed Data Converter Pro started properly. Take note of the Serial Numbers of the TSW14J56 EVM after the device is connected.

  3. Within the Microsoft Windows PC, start the Latte software by going to Start > Texas Instruments > Latte. Ensure that the Latte software had started properly.
  4. On the left hand side of the Latte, within the Scripts window, expand AFE79xx > Automation > AFE79xx_TSW14J56_Mode1.py. Figure 4-3 shows the python script.

  5. Three parameters within the AFE79xx_TSW14J56_Mode1.py must be changed per the directory being used by the High-Speed Data Converter Pro software and the Latte software.
  6. As shown in Figure 4-4, change item #1 and #2 to reflect the location of the Latte install directory for the setup.py and devInit.py. Usually the area where a0xxxxxx must be replaced with the Windows user ID login.

  7. As shown in Figure 4-4, change item #3 to reflect the location of the High-Speed Data Converter Pro directory for the TSW14J56 firmware.
  8. As shown in Figure 4-5, enter the serial number of the TSW14J56 EVM per the highlighted location in .

  9. With the AFE79xx_TSW14J56_Mode1.py highlighted, press the F5 button to execute the script. The script will automate both High-Speed Data Converter Pro software and Latte software to automatically bring up the JESD204B link.
  10. As shown in Figure 4-6 and Figure 4-7 expect the following two error messages after the script runs.

  11. The default TRF1208-AFE7950-EVM has the following RF frequency matching network:
    1. RXA (TRF1208): 2.3 GHz
    2. RXB (TRF1208): 5 GHz
    3. RXC (TRF1208): 8 GHz
    4. RXD: None
    5. FB1 (TRF1208): 6 GHz
    6. FB2 (Differential connectors): 6 GHz
    7. TXA (TRF1208): 6 GHz
    8. TXB (Balun): TBD GHz
    9. TXC (Balun): 6 GHz
    10. TXD (Balun): TBD GHz
  12. The example script to change the NCO to match the default RF frequency matching network is the following: 
    AFE.updateTxNco(0,6000,0,0)
AFE.updateTxNco(1,6000,0,0)
AFE.updateTxNco(2,6000,0,0)
AFE.updateTxNco(3,6000,0,0)
AFE.updateRxNco(0,2300,0,0)
AFE.updateRxNco(1,5000,0,0)
AFE.updateRxNco(2,8000,0,0)
AFE.updateRxNco(3,6000,0,0)
AFE.updateFbNco(0,6000,0)
AFE.updateFbNco(1,6000,0)
  13. As shown in Figure 4-8, enter the commands in the command line prompt or execute AFE79xx_DC101_NCO_Setup.py (under Automation Folder of AFE79xx) in the Latte through F5 key.
