Getting Started Application GUI

The TIDA-01022 board requires three application software GUIs for validation: HSDC TID GUI, HSDC Pro GUI, and the LMK61xx Oscillator Programming Tool.

  1. Use the HSDC TID GUI to configure the data converter (ADC12DJ3200), clocking devices (LMK4828, LMX2594, and LMK61E2), and digital VGA (LMH6401). Use the low-level page to program the device with the respective configuration file. Download the latest HSDC TID GUI software at: http://www.ti.com/lit/zip/tidcdr5.
  2. Use the HSDC Pro GUI to capture the digitized data with the assistance of a TSW14J56 capture card and provide a spectrum and time domain plot. Download the latest HSDC Pro GUI software at: http://www.ti.com/tool/dataconverterpro-sw.
  3. Use the LMK61xx Oscillator Programming Tool to program the LMK61E2 device. Download the latest LMK61xx software at http://www.ti.com/lit/zip/snac074.

Figure 6-1 and Figure 6-2 show screenshots of starting the HSDC TID GUI configuration and the programming tab for the low-level view, respectively.
