Other Parts Discussed in Thread: LMK04828,
Tool/software:
Hello,
I have custom board with LMK04828 and ADS54J60 in it. I have configured the register required. I have measured the clocks generating from the LMK04828, 122.88Mhz sys_clock, 3.84Mhz sys_ref, and adc sampling frequency is 983.04Mhz.
The register data is given in "ADS54J60_ZC706.cfg" file.
The issue that I am facing is " I am giving an input frequency of 500KHz to the ADS54J60 (period - 2us). But when the samples that are plotted in HSDC Pro is giving 400KHz(period - 2.5us)".
I have attached a screenshot of the pulse plotted in HSDC Pro. I have measured the frequency at the input of the ADC which was 500KHz, but in the image you can see that it is in 390 - 400KHz.
What is causing this problem. Please let me know what are the changes to done and if you need any details related to this.
Thank You,
There is no decimation enabled. ADS54J60_ZC706.cfg
