Megumini

Thanks for your experience sharing~ I appreciate that a lot~ I might share it later after I get my system running. (but they gonna arrive after 5 months....)

I am so glad that you replied. (I was planning to send you a dm after reading your replies on other posts) Thanks for your suggestions, I gonna check integrated solutions. (they are very expensive). Also had a sad experience based on that. Because the previous all-in-one board stopped supporting, and had very limited flexibility. It's just sad that add-on card is not good... Thanks!

Thank you for your reply! I will continue searching.

I am a newbie with exp 2/1000 to next level (which only took courses and work with System Generator with Xilinx blocks in Simulink once long time ago). But at some point I have to make a decision to purchase new equipment and develop a data acquisition+signal processing system on top of it (hell challenging). I tried to read posts in this forum, tried to contact with vendors. But because it is really big budget (20k including IP license, debugging etc...) plus I am such a beginner, I decided to do as much homework as I can before I make the decision. The requirements are: Quad Channel ADCs with sampling frequency within range: 400-600MSPS, resolution 14bits or more. Prefer no decimation before signal processing. Phase information between those channels are really important, which means they should be synced very well. (theoretically Amplitude imbalance between channels less than 1dB, phase imbalance less than 10 degrees..) The sampling frequency band of interest is 100-150MHz, not very wide. Other requirements like CDR more than 70dB, SFDR more than 60dB (most ADCs I checked meet those requirements) And FPGA...Just need pair with the ADC, virtex 7 or Kintex UltraScale+ or Virtex UltraScale+ I guess? Estimate DSP slices more than 4000. (if do parallel fir), but I saw some ADC has NCO then it can even go down. Questions: 1. If I found a nice ADC, should I choose Evaluation board from Analog Devices or third party vendor platform solution? 2. Anything else I have not considered yet..Like Vpp and adc solution etc. 3. Should I try to build the system in vivado to get more precise resources report.. 4. What usually should I expect to come with products, like IP core? VHDL code? Configuration binaries? Examples? 5. JESD204B can guarantee the synchronization between separate FMC, is that a good option? like 2 * 2channelADCs instead of 1*4channelADCs 6. Oh yeah...suggestions of products. (did you see how panic I am ? (╯°□°)╯︵ ┻━┻)(no need for answering everything, if I mess up, I gonna just run away from my work, its ok...) (Thank you so much for even finish reading till here)
