Hello Luke,
thank you for your help. I would provide you more information now:
1.At the start ,we use the clock on board, and we test the input differential clock of the ADC using a RS spectrum analyzer. And afterwards, we conect a external clock , the 800M differential clock is also normal.
2.We are sure the power is supplied successfully!!
3.The led pattern is same as the board user guide and the patter in your reply except the DCKL_LOCKED LED.
4.We check the version of the FPGA image,it is shown in the following:
at earlier time, we also doubted if this board is not matched with the FPGA image, but we don't know how to get the right FPGA image even though it is not matched with the board at hand.
5 Here we would like to give you the picture of our bord :
6.the version of WV5 is 5.0.6.465, we don't know if it is the newest,but we only find this version on the websitehttp://www.ti.com/tool/WAVEVISION5 . The web site you provide can''t be opened.
7. we have also watch the demo vedio on the website http://www.ti.com/tool/adc12d800rfrb.we foud tha the board is a litte different of ours.The logo is NS, but not TI. It looks like as the following:
8 also on the website metioned in 7 ,there is a ADC12D800RFRB Design Package we downlowd it ,finding the schematic is not matched with our board. So,we are very puzzled by the version of board、 software、FPGA image、and design package.
9 For one more thing ,why the number on the on board clock PLL is VM AB24E3 4123203 but not LM2531 or LM2541.?We googled the number but found nothing.
Thank you very much! Looking forward to your reply!
