Programming Interface

After the 3.3-V power supply has been connected and power has been applied to the EVM, connect the USB cable from the PC to the EVM. The USB interface will provide the necessary power to enable the onboard USB2ANY controller. A firmware update may be required; if prompted, see Appendix B for more details.

Run TICS Pro software and open the device profile:

  1. From the top-menu, click Select Device → Clock Distribution with Divider → LMX1204

  2. The device's Main Page will load. The default profile is configured for 800-MHz buffer mode.

  3. From the top-menu, click USB communications → Interface. Ensure that the selected interface is USB2ANY and that the correct controller is selected. To confirm controller selection, click the Identify button to blink the onboard green communications LED several times in rapid succession; the LED will return to solid green when complete. After confirming the USB2ANY connection, close the interface window.
