and that the configuration procedure was followed.
LEDs not flashing – reprogram the LMK device.
Try pressing the CPU_RESET button on the TSW14J56EVM.
Try capturing data in HSDC Pro to force an LED status update.
Device GUI is not working properly.
Verify that the USB cable is plugged into the EVM and the PC.
Check the Device Manager of the computer, and verify that a USB Serial
Device is recognized when the EVM is connected to the PC.
Verify that the green USB Status LED light in the top-right corner of the
GUI is lit. If the LED is not lit, press the Reconnect FTDI button.
Try restarting the configuration GUI.
Check default jumper connections as shown in Appendix A.
HSDC Pro Software is not capturing good data or
analysis results are incorrect.
Verify that the TSW14J56EVM is properly connected to the PC with a
mini-USB cable, and that the board serial number is properly identified by
the HSDC Pro software.
Check that the proper ADC device is selected. In default conditions,
ADS54J64_LMF_4841_mode01 must be selected.
Check that the analysis parameters are properly configured.
HSDC Pro Software gives a time-out error when
capturing data. Try to reprogram the LMK device and reset the JESD204 Link.
Verify that the ADC sampling rate is correct in the HSDC Pro software.
Sub-optimal measured performance
Try pressing the Calibrate ADC button on the INTRO tab, to repeat the

3 Optimizing Evaluation Results
This section is meant to assist users in optimizing performance during evaluation of the product.
3.1 ADS54J64 Operating Mode
The ADS54J64 device may operate in eight different modes: Mode 0 through Mode 8 (excluding Mode 5).
Each mode may require a different device selection in HSDC Pro, device configuration script in the
ADS54J64 EVM GUI, and different sampling rate setup in HSDC Pro to operate correctly.
Table 3 shows the HSDC Pro sampling rate setup. The desired mode is selected from the ADS54J64EVM
GUI →Mode tab in the configuration GUI.
(1) The ADC Sampling Rate used in HSDC Pro for Mode 7 depends on the .ini file used. The example shown here applies to
selecting ‘ADS54J64_LMF_4421_mode7’ which strips the buffered 0s from the data stream.

For operating in a mode other that Mode 0, follow the default start-up procedure, and then perform the
following:
1. From the ADS54J64 Mode tab in the configuration GUI, select the desired mode.
2. When selecting the device in HSDC Pro (), choose the device and enter the ADC Output Data Rate as
reported by the configuration GUI on the ADS54J64 Mode tab.
Based on the sampling rate and mode of operation, adjust ADC Output Rate Additional Device
Parameters to correctly label the harmonics. An example is shown in Figure 4 for Mode 0.
