ADS54J20EVM Setup
Next, setup the ADS54J20EVM using the following:
1. Connect the included 5-V power supply cable to connector J9 of the EVM. Connect the red wire to +5
VDC ±0.1 VDC of a power supply rated for at least 3 A. Connect the black wire to GND of the power
supply.
2. Connect the included mini-USB cable to the USB connector J8.
3. Turn on the power supply. The power draw should be around 0.66 A. When the board is configured, it
will draw approximately 1.35 A.
4. Set the analog input signal generator for 170 MHz, and about +15 dBm of power.
5. Place a narrow pass-band band-pass filter at the output of the analog signal generator to remove noise
and harmonics from the signal generator.
6. Connect the analog input signal generator to the EVM though SMA connector AINP (J2).

Software Setup Procedure

The software can be opened and configured once the hardware is properly setup.
2.3.1
ADS54J20 GUI Configuration
1. Open the ADS54Jxx EVM GUI by going to Start Menu → All Programs → Texas Instruments ADCs →
ADS54Jxx EVM GUI.
2. Verify that the green USB Status indicator is lit in the top right corner of the GUI. If it is not lit, click the
Reconnect USB button and check the USB Status indicator again. If it is still not lit, then verify the EVM
is connected to the computer through the included mini-USB cable.
3. Click on the Low Level View tab then click the Load Config button.
4. Navigate to C:\Program Files(86)\Texas Instruments\ADS54Jxx EVM GUI\Configuration Files, select
the file called LMK_Config_Onboard_983p04_MSPS.cfg, then click OK. This programs the LMK04828
to provide a 983.04 MHz clock to the ADC.
5. Verify that the LMK04828 phase lock loop (PLL) is locked by checking that the PLL2 LOCKED LED
(D3) is lit.
6. Once the LMK04828 PLL is locked, press SW1 (ADC RESET) to provide a hardware reset to the ADC.
This switch is located in the middle of the EVM.
7. In the Low Level View tab, click Load Config. Select the file called ADS54J20_LMF_8224.cfg and click
OK. The ADS54J20EVM is now configured for no decimation and 8 JESD204B lanes.
