LMK and LMX Clocking for ZCU111 DAC

Hi

I have a design that generates sinewave and feeds to DAC. The design validates without errors. The settings of the DAC are as shown in below snapshots. How to configure the clocks? I heard that TICS Pro can be used. but I am not understanding how to generate clocks for the following values. Please help.

Hi @ksram1988 

Here you sampling rate is 800 MSPS and sampling clock is coming from LMX2594 chip on the board , so you need to program the LMX2594 to output the 800MHz, 

as LMX2594 is from TI , the TICS Pro is used to generate the clocking file , either .tcs/,txt , you can use these files and program the LMX2594 using SCUI for ZCU111.

The SCUI is available here to download and its tutorial.

There is another way to program the clock chips on the board via Linux (i2c-tool) or via a C application on the A53.
