2.3.1 AFE79xx EVM and TSW14J58 EVM Connections

  1. Connect the FMC connector U31 of AFE79xx EVM to THE FMC connector J3 of TSW14J58 EVM.
  2. With the power supply in powered-down mode, connect a 5.5V, 5A maximum power supply to J2 +5V IN connector of the TSW14J58EVM.
  3. Connect a USB 3.0 cable from the PC to J1 connector of the TSW14J58 EVM.
  4. Connect a USB Mini-B cable from the PC to FTDI_USB connector of the TSW14J58 EVM.
  5. With the power supply in powered-down mode, connect the 5.5V, 5A maximum power supply to J18 connector of the AFE79xx EVM.
  6. Connect a USB Mini-B cable from the PC to J19 connector of the AFE79xx EVM.
  7. Optionally: Connect 10MHz of lab equipment reference to J14, LMK_CLK_IN connector.
  8. Optionally: Choose the FPGA bitfile version by changing J35 jumper position.
    1. Default: For bitfile version 204B, check that the physical position of jumper J35 is covering pins 2 and 3 (the two pins positioned furthest from the FPGA fan).
    2. For bitfile version 204C, check that the physical position of jumper J35 is covering pins 1 and 2 (the two pins positioned nearest to the FPGA fan).
    3. The configuration steps in this guide assume the user is using bitfile version 204B.

Refer to Figure 1-2 for the typical connection between the TSW14J58 EVM and the AFE79xx EVM. TI recommends connecting the USBs directly to the PC, rather than a USB hub, and disconnect unnecessary USB devices from the PC. Other USB devices can potentially interfere with the ability of the PC to recognize the EVM USB handles.

After completing these steps, turn on the power supplies.
