ADS54J/58J6XEVM Setup

Next, setup the ADS5XJ6XEVM with the following instructions:

1. Connect the included 5-V power supply cable to connector J14 of the EVM. Connect the red wire of

the power cable to +5 VDC ±0.1 VDC of a power supply rated for at least 3 A. Connect the black wire
to the GND terminal of the power supply.

2. Connect the included mini-USB cable to the USB connector J13

3. Set the analog input signal generator for 170 MHz, and about +15 dBm of power

4. Place a narrow passband band-pass filter at the output of the analog signal generator to remove noise

and harmonics from the signal generator

5. Connect the analog input signal generator to the EVM though SMA connector AIN (J1)

2.3

Software Setup Procedure

The software can be opened and configured once the hardware is properly setup.

2.3.1

ADS54J/58J6X GUI Configuration, Mode 0

1. Open the ADS54Jxx GUI by going to

Start Menu

All Programs

Texas Instruments ADCs

ADS54Jxx 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 GUI\Configuration Files”, select the

file called “LMK_Config_LMF_4841_491p52_MSPS.cfg”, then click “OK”. This will program the
LMK04828 to provide a 491.52-MHz clock to the ADC.

5. Verify that the LMK04828 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 “ADS5xJ6x_2x_Fs_4_mode_0.cfg”

and click "OK". The ADS5XJ6XEVM is now configured for a fixed frequency Fs/4 complex digital mixer
and decimate by 2 digital filter mode using 4 JESD204B lanes.
