DEARS.

I installed the ADC32J45EVM GUI(ADC3000).
I can not find the "ADC3xJxx_160MSPS_Operation_LMK_Setting.cfg" file in the guide document.
The installed CFG folder contains Config1, Config2.
The contents are as follows.
How does it work?

Hi Henry

When you downloaded the ADC32J45EVM GUI installer it should have been a file named slac667c.zip.

Inside that .zip file is a sub-folder named ADC3xxxx with the installer. In the root of the zip folder are 3 .cfg files:

ADC3xJxx_80MSPS_Operation_LMK_Setting.cfg
ADC3xJxx_128MSPS_Operation_LMK_Setting.cfg
ADC3xJxx_160MSPS_Operation_LMK_Setting.cfg

You will need to locate these files and copy them into this folder location:

C:\Program Files (x86)\Texas Instruments\ADC3xxxx\Configuration Files

Please let us know if you can't locate the files and are still having issues.

Best regards,

Jim B

Hi Henry

Here are the 3 files contained in the installer .zip.

/cfs-file/__key/communityserver-discussions-components-files/73/1682.ADC3xJxx_5F00_80MSPS_5F00_Operation_5F00_LMK_5F00_Setting.cfg

/cfs-file/__key/communityserver-discussions-components-files/73/1401.ADC3xJxx_5F00_128MSPS_5F00_Operation_5F00_LMK_5F00_Setting.cfg

/cfs-file/__key/communityserver-discussions-components-files/73/2210.ADC3xJxx_5F00_160MSPS_5F00_Operation_5F00_LMK_5F00_Setting.cfg

Best regards,

Hi Jim B

The setting values of the following files are the same.
The Register values of 80Msps, 128Msps and 160Msps are the same.
All values are zero.
ADC3xJxx_80MSPS_Operation_LMK_Setting.cfg
ADC3xJxx_128MSPS_Operation_LMK_Setting.cfg
ADC3xJxx_160MSPS_Operation_LMK_Setting.cfg

The customer setting values are as follows.
We need the setting of ADC32J45.
You need a setting value that can be guided.

Device Clock : 153.6Mhz
SYSREF : 9.6M, Duty 50%
Line Rate : 3.072Gbps
Subclass 1
LMFS : 2221,
K=16

Thank you.

150M_K16_2221_ADC32J45.cfg ADC32J2x_LMF_222_K16.iniHenry,

The EVM cannot be configured for this clock rate. You must either swap the VCXO to a 122.88MHz VCXO or provide an external clock source. I was able to generate a configuration file that will sample the ADC at 150MHz. This is attached along with a new ini file for HSDC Pro to set the K value = 16.

Regards,

Jim
