3.9 Open the DAC12DL3200EVM GUI and Program the DAC and Clocks for Single Channel, NRZ Mode 2 Operation

The device configuration GUI is installed separately from the HSDC Pro installation and is a stand-alone GUI.

Figure 3-2 shows the GUI open to the LMK04828 tab. Tabs at the top of the panel organize the configuration into device and EVM features, with user-friendly controls and a low-level tab for directly configuring the registers. The EVM has three configurable devices: the DAC12DL3200, LMK04828, and LMX2592. The register map for each device is provided in the device data sheets.

Figure 3-2 illustrates the DAC12DL3200EVM GUI showing the USB status is connected to a PC.

  1. Open the DACDL3200EVM GUI by clicking on the DAC12DL3200 GUI icon and run as administrator.
  2. Verify the USB has connected to the board. This is indicated by a green USB Status indicator in the top right corner of the GUI. If this is not lit, click on the Reconnect? button until it does illuminate.
  3. Click on the Low Level View tab.

    Figure 3-3 illustrates loading a register configuration file to the EVM.

  4. Click on the File icon and navigate to “EXT_CLK_Mode2_NRZ_Single_DAC.cfg” and click on the OK button to load the LMK and DAC registers, see Figure 3-4.

This configuration file sets up the DAC to operate in a single-channel mode with the output available only on CHA. The same output is available on CHB in this mode if desired, but the configuration file has CHB powered down by default.
