Honored ContributorHi uzmeed,
Your system definition is better, but still not complete. As far as hardware goes, you need 6 channels of 14-bit ADCs capable of sampling a 20MHz bandwidth video signal. However, how much FPGA logic do you require for processing that data? Do all the data streams need to be processed together, or are they independent? Why is this important? Well, if you can find a 2-channel ADC board, then you can use three of those. For example, Terasic have an AD/DA board with two 14-bit ADCs that can operate to 150MHz. If you can clearly state your project requirements, then I can review them, and you can start a new thread requesting advice on what hardware other people on the forum recommend. How much can you spend on buying hardware for this project? Why do these video streams need to be sampled? Can you not get them in a digital form, eg. HDMI, SDI, etc? If the project can change the format of the video source, perhaps there is a simpler (cheaper) FPGA solution. Cheers, Dave
